they cannot initiate its own communication, and can only respond to a host command when properly addressed. the irda protocol uses a transceiver chip in both devices to send and receive data packets. the packets are checked for validity, and a response is sent by the secondary device indicating whether the packets were complete or in error. the irda protocol is contained in three layers: the physical electronics are the hardware elements in each device for sending and receiving the data. the link access protocol (lap) layer controls the physical layer, packetizes/unpacketizes data, and sets transmission rates. the link management protocol (lmp) layer routes data to and from the host operating system (dos/windows). the data flow is shown in figure 7. the lap and lmp layers can reside in either firmware, software, or a combination of both. there are different lap and lmp protocols for primary and secondary devices. the hp laserjet 5p printer has the complete secondary protocol, and any host trying to communicate via the infrared (ir) port must have the complete primary protocol installed. the primary protocol software is the responsibility of the host supplier. it is not provided by hewlett-packard company with the printer. irda communications can be obtained either via an internal ir port or an external ir accessory. several manufacturers offer complete accessory upgrades for both host and peripheral devices. hp laserjet 5p printer service supplement new product features 18 system requirements hardware both the primary and secondary devices must be equipped with an irda-compliant ir component. older, non-irda- compliant devices may not be compatible with the hp laserjet 5p/mp printers. software the primary device must be loaded during boot-up with software provided by the manufacturer for infrared operation. the primary device must be properly configured with an infrared com port, irq level, and base address value. the infrared port must be installed and selected in the printers section of the windows control panel. protocol serializer ir chip application gdi ddi ptr dvr irlmp irlap ir physical transmitter receiver receiver transmitter ir physical irlap irlmp i/o buffer formatter data packets & queries responses secondary device primary device ascii data windows system standard windows lj printer driver (sw) ir redirector (software) ir driver packetizes data (sw or fw) ascii to raster data ascii data buffer unpacks data checks packets protocol deserializer ir chip figure 7. ir data flow. hp laserjet 5p printer service supplement new product features 19 to print using the infrared port the infrared (ir) port on your hp laserjet 5p or 5mp printer is located on the lower front left corner of the printer (figure 8). this port is compliant with the specifications determined by the infrared data association (irda). just above the port is a status light that indicates when the port is activated. to use the ir port, you need to use a portable device that also includes an irda-compliant ir port and be within the range of operation (see figure 9). the ir port is compatible with a wide variety of irda-compliant portable devices; however, the method for printing will vary depending on the type of device and the operating system in use. refer to the instruction manual for your portable equipment for specific instructions on printing from that device. the ir port works by receiving data similarly to a serial port, however, without a cable and operates at speeds of up to 115 k bits per second. when the ir connection is established, the status light comes on. if the connection is broken or when the print job is complete, the status light goes off. 1. make sure the printer is in ready mode (the ready light is on). 2. align your laptop computer (or other portable equipment) that is equipped with an irda-compliant ir port within 3 feet figure 8 irda port location hp laserjet 5p printer service supplement new product features 20 (1 m) of the ir port on the printer and at an angle of 15 degrees to ensure printing (figure 9). 3. send the print job. the status light above the ir port turns on (printing a complex document or using a software print spooler on your pc may delay the time it takes for the ir status light to turn on). if the status light does not turn on, realign the port on your portable equipment with the port on the printer, resend the print job and stay within the range of operation during printing. 4. if you have to move the device, for example, to add paper, make sure you stay within the range of operation to maintain the connection. if the connection is interrupted before your print job is complete, the ir port status light will turn off. you have from 3 to 40 seconds (depending on the host implementation) to correct the interruption and continue the job. in this case, the ir port status light turns back on. 5. the connection can be permanently broken (interrupted for more than 3 to 40 seconds) if the ?sending? ir port is moved out of the range of operation or if anything passes between the two ports to block the transmission, such as a hand or piece of paper, or even direct sunlight. in this case, the job needs to be reprinted. 30 1 meter 3 feet figure 9 irda port ranges hp laserjet 5p printer service supplement new product features 21 if you still have problems printing, make sure you are using an irda-compliant device and proper software and have selected the proper port for printing. see "infrared port not responding" on page 65. note the irda standard for infrared communications represents an emerging technology. older non-irda-compliant portable devices may not be compatible with your hp laserjet 5p/5mp printer. if you continue to have problems printing using the ir port, contact the manufacturer or dealer where you purchased your portable device to verify compatibility with the irda standard, and follow the troubleshooting procedure immediately following. troubleshooting ir printing problems ir printing problems may be caused by any of the several system components or by lack of proper configuration. the following checklist will help determine the source of the problem. 6. verify the user is operating the printer and pc as described in the user?s manual: less than one meter between devices, and not more than 15 degrees from direct center. 7. verify the host pc or laptop and the printer are irda-compliant and have the necessary hardware components for ir communication. 8. verify the ir software has been loaded on the primary device. (this is system software and should be available from the pc manufacturer.) 9. verify the host pc or laptop is properly configured. check the port assignment, the irq level, and the base address value. check both the dos autoexec.bat and config.sys files, and the windows system configuration. hp laserjet 5p printer service supplement new product features 22 if all these elements are properly installed and configured, use the ir test tool to test the irda protocol transmission and device operation. this tool for troubleshooting ir communication problems, shown in figure 10, has been developed by genoa technology, inc., in cooperation with hewlett-packard. the part number is 5062-4661 and can be ordered through hp parts direct ordering. the ir test tool can be used with any irda-compliant primary or secondary device, regardless of manufacturer. to test the peripheral device: 1. put the hp laserjet 5p in ready mode. 2. press the "peripheral test" button on the test tool. the leds on the test tool will sequence. lb test connect pass peripheral test computer test test modes pcl printer postscript printer energy detect test frame switches ir diodes figure 10 infrared test tool hp laserjet 5p printer service supplement new product features 23 if the "pass" led lights, the test was successful, indicating that communication with the printer?s ir port is functioning normally. on hp laserjet printers, a self-test page will be initiated by the test. if the "test" led goes out and the "pass" led fails to light, the printer?s ir port is not functioning correctly; check the operator?s instructions included with the ir test tool. to test the host computer: 1. place the test tool on a table in front of the pc?s ir port 2. press the "computer test" button. the test tool will sequence the leds. if the "pass" led light, the test was successful, indicating that communication with the printer?s ir port is functioning normally. if the "test" led goes out and the "pass" led fails to light, the host?s ir port is not functioning correctly. hp laserjet 5p printer service supplement new product features 24 interface connections your hp laserjet 5p or 5mp printer supports the following interfaces (see figure 11): two ieee-1284?compliant parallel ports at the back of the printer?one large b-type and one small c-type. one localtalk port at the back of the printer. one irda-compliant infrared port at the front of the printer. 1. localtalk cable and connectors. 2. ieee-1284 parallel cable and large (b-type) printer connector. 3. i eee-1284 parallel cable and small (c-type) printer connector. (the cable will be stamped as ieee-1284 compatible. 4. host pc connector (a-type) (in the future c-type connectors may also be available on host pcs). caution make sure that all power and interface cables on your printer and host computer are properly grounded and in compliance with local electrical codes. figure 11 hp laserjet 5p/5mp printer interface connections hp laserjet 5p printer service supplement new product features 25 the parallel printer interfaces these interfaces are compliant with ieee-1284 specifications for "compatibility mode? and ?nibble mode? or ?hp bi-tronics?. to use advanced interface functions, such as bi-directional communication, the parallel port on your host pc must also be ieee-1284 "nibble mode" compatible. the small ?c? connector offers ieee-1284 ii (level 2) electrical interfacing, i.e. support for cables up to 10 meter length. the large "b" connector supports standard cable lengths up to 3 meters. the parallel interfaces can operate at speeds of up to 2 mbytes per second. use a high-quality, shielded ieee-1284 compliant parallel interface cable to insure best performance and support of advanced interface functions such as bi-directional communication. compliant cables are marked with ?ieee-1284" on the cable. applications such as the remote control panel, status monitor, or the status window use the printer?s parallel interface to send status information back to the computer (bi-directional communication). this requires a direct connection from the computer to the printer via a local parallel port (for example, lpt1:, lpt2:). these applications may not work through a network or a switching device. connecting to networks and switchboxes most devices connected between the printer and the host computer prevent the printer from sending data back to the computer. therefore, the remote control panel, status monitor, and status window may not work with networks, most hardware print spoolers, some software print spoolers, and some switchboxes. newer sharing devices are available that fully support status feedback. check with your supplier on support for bi-directional communication. automatic i/o switching the printer automatically switches between all interfaces (parallel, infrared, and localtalk) when multiple users share the printer. hp laserjet 5p printer service supplement new product features 26 resource saving resource saving gives the printer the ability to save certain entities such as permanent soft fonts, macros, symbol sets and user-defined graphics patterns when the printer changes personalities, resolutions or page protect modes. for example, if a user switches the printer from pcl mode to postscript mode, all pcl soft fonts and macros are lost. with resource saving, the hp laserjet 5p/5mp printer can retain these in memory. when the user switches back to pcl from postscript all of the pcl entities would still be resident in the hp laserjet 5p/5mp printer. resource saving can be changed via software, but can only be accessed when the printer has the postscript language installed and a minimum memory configuration of 7 mb. resource saving can be set via software for one of three modes, auto (default), on, and off. auto configuration sets the resource saving for pcl and postscript to a minimum value (400 kbytes) for each personality. setting resource saving to on allows the user to determine how much printer memory will be used for resource saving for the pcl personality and the postscript personality. the memory can be allocated in 100 kbytes increments. for example, if the user sets the resource saving memory size to 200 kbytes, a total of 400 kbytes of memory will be assigned to resource saving. 200 kbytes of memory will be used for postscript resource saving and 200 kbytes of memory will be used for pcl resource saving. turning resource saving off disables the resource saving function and no memory is allocated to resource saving. hp laserjet 5p printer service supplement new product features 27 i/o buffering i/o buffering allows the user to allocate printer memory to hold the job while it prints, freeing up the host system sooner, like a print spooler. the standard printer has approximately 10 kbytes of memory allocated to i/o buffering and an additional 100 kbytes of memory is assigned to i/o buffering for each mbytes of memory added to the printer. if the printer has a minimum of 6 mbytes of memory installed, the i/o buffer size can also be adjusted via software. three settings exist for the i/o buffer; auto (default), on, and off. auto sets the printer?s i/o buffer to a minimum value that is determined by the total amount of memory that is resident in the printer. setting i/o buffering to on allows the user to set the i/o buffer size setting the i/o buffering to off disables i/o buffering . note when you change the i/o buffer setting all downloaded resources are deleted. hp laserjet 5p printer service supplement new product features 28 this page intentionally left blank hp laserjet 5p printer service supplement new product features 29 service mode, pjl defaults the service mode should be used only by authorized service personnel. while in service mode, you can: print a service mode self test. verify and set the page count (the page count also is displayed on the standard self test). set the cold reset default.

(for software developers use only). since the hp laserjet 5p/5mp printer does not have a front control panel, service mode and many configuration tasks are accessible only through software (pjl commands). the following example shows how to use pjl commands to enter service mode and perform various service mode configuration tasks. note text is case-sensitive in pjl; enter exactly as shown. the e c symbol stands for the ascii escape character (esc or /027). when the pjl code is entered, print the data file (or use the dos copy command to copy it to the printer). detailed explanations of

includes an ir driver and your application uses a hp laserjet 5p/5mp compatible printer driver. make sure you have positioned the device within the range of operation and that no objects, such as a finger, paper, books, or bright light, are interfering with the connection. also make sure the two ir ports are clean (free from dirt and grease). bright light of any kind (sunlight, incandescent light, fluorescent light, or light from an infrared remote control, such as those used for tvs and vcrs) shining directly into one of the ir ports may cause interference. position the device closer to the ir port on the printer. the printer prints only part of a page or document. the connection has been broken during transmission. if you move the portable device during transmission, the connection can be broken. irda-compliant devices are designed to recover from temporary connection interruptions. re-establish the connection (depending on the device you are using, you can have anywhere from 3

laserjet 5p/5mp printer has two buttons: go and reset. the hp laserjet 6p/6mp printer has two buttons: go and job cancel. pressing the go button: tells the printer to resume printing. prints a demo page. the printer must be in ready mode (the green ready light on steady). prints a self-test page when pressed simultaneously with the reset button (job cancel button on the 6p/6mp. the printer must be in ready mode (the green ready light on steady). prints unprinted data in the printers memory (the ready and data lights are both on steady). pressing the reset button: (available on 5p/5mp) clears incomplete print jobs from the printers memory. clears errors. removes all temporary fonts and macros. returns all printer settings to the default values that you selected. pressing the job cancel button: (available on the 6p/6mp) press to cancel a job that the printer is currently printing. the top status panel lights will cycle while the printer memory is being cleared, and then return to a ready state (front light on). the printer will continue receiving data until the job is complete. this data will be discarded. this may take a while, depending on the size of the print job. if job cancel is accidentally pushed, the job must be reprinted. there is no undo function. if job cancel is pushed when the printer is idle, the top panel status lights will cycle, but nothing else will happen. hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 12 status panel lights there are six status panel lights on the printer: error tray 1 data tray 2 ready ir status these lights indicate the current status of the printer by displaying an amber or a green hue and flashing individually or sequentially as a group (cascading). error (amber) indicates an error condition, such as a paper jam, missing toner cartridge, or the printers top cover is open. data (green) when the data light is on, the printer is printing. when the ready light and the data light are both on, the printer still has unprinted data in its memory. either press go to print the remaining data, or press reset/job cancel to clear the data from the printers memory. ready (green) the printer is in ready mode when the ready light is on. if the light is flashing, the printer is currently receiving data or in the process of printing. tray 1 (amber) tray 1 (the mp tray) is empty. add paper to tray 1. when the tray 1 light is flashing, the printer is waiting for paper to be manually fed into tray 1. once you have inserted the paper, you must press the go button to feed the paper. tray 2 (amber) tray 2 (the paper cassette) is empty. add paper to tray 2. hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 13 ir port status light (green) the status light above the ir port indicates the current status of the ir port by displaying a green hue. this status light comes on when a connection has been established with the ir port. the other status panel lights operate the same for the ir port as they do for any other port on the printer. common led patterns the following chart shows the light patterns for normal hp laserjet 5p/5mp and 6p/6mp printer states. if the error light is on, the printer is experinecing an error. error messages are listed later in this appendix. light pattern description 5p/5mp 6p/6mp the printer is in ready mode and is

light and the ready light are both on for an extended period of time (the ready light does not begin to flash), press the go button to print the data in the printer. a page may take a long time to print if, for example, the page contains complex text or graphics. if each light briefly turns on and off, in sequence, the printer is warming up, processing a self test, or canceling a print job.the lights will continue to ?cascade? until the printer is ready to print. tray 1 (the mp tray) is empty. add paper to the tray. hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 15 light pattern description 5p/5mp 6p/6mp if the tray 1 light is flashing, the printer is waiting for paper to be manually fed into tray 1. once you have inserted the paper, you must press the go button to feed the paper. tray 2 (the paper cassette) is empty. add paper to the tray. when the ir port status light is on, a connection has been established. if you are printing to the ir port and the status light does not come on, make sure the printer is in ready mode and that the ir port you are printing from is within range of operation and is irda- compliant. if you continue to have trouble printing, refer to the ?infrared port not responding? table, later in this section. hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 16 paper movement overview the paper feed system picks print media automatically from tray 1 or tray 2 and delivers it to the image formation system at precisely the right time. the system then feeds the media to the fusing station, and delivers the finished product to the output position, either the face-down output tray on top of the printer, or through the face-up delivery slot at the rear of the printer. the output path is user-selectable by opening the rear output tray. figure 7 shows the possible paper paths and locations of the various solenoids, photosensors and rollers. hp laserjet 5p/5mp, 6p/6mp printer

hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 18 infrared communication the hp laserjet 5p/5mp and 6p/6mp printers are equipped with an infrared datalink association (irda) compliant port. the irda specification allows wireless transmission of print data between a wide variety of hosts (primary) and peripheral (secondary) devices. a primary device -- such as a pc or laptop computer -- is capable of reading and writing data to another primary device or writing to a secondary device, such as a printer. secondary devices are read-only; they cannot initiate their own communication, and can only respond to a host command when properly addressed. the ir port works by receiving data similarly to a serial port, but without a cable. the ports speed depends on the printer model: hp laserjet 5p/5mp printer 115 k bits per second hp laserjet 6p/6mp printer up to 4 megabits per second when the ir connection is established, the status light comes on. if the connection is broken or when the print job is complete, the status light goes off. the irda protocol uses a transceiver chip in both devices to send and receive data packets. the packets are checked for validity, and a response is sent by the secondary device indicating whether the packets were complete or in error. the irda protocol is contained in three layers: the physical electronics are the hardware elements in each device for sending and receiving the data. the link access protocol (lap) layer controls the physical layer, packetizes/unpacketizes data, and sets transmission rates. the link management protocol (lmp) layer routes data to and from the host operating system (dos/windows). the data flow is shown in figure 8. hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 19 the lap and lmp layers can reside in either firmware, software, or a combination of both. there are different lap and lmp protocols for primary and secondary devices. the hp laserjet 5p/5mp and 6p/6mp printers have the complete secondary protocol, and any host trying to communicate via the infrared (ir) port must have the complete primary protocol installed. the primary protocol software is the responsibility of the host supplier. it is not provided by hewlett-packard company with the printer. irda communications can be obtained either via an internal ir port or an external ir accessory. several manufacturers offer complete accessory upgrades for both host and peripheral devices. protocol serializer ir chip application gdi ddi ptr dvr irlmp irlap ir physical

component. older, non-irda- compliant devices may not be compatible with the hp laserjet 5p/5mp and 6p/6mp printers. software the primary device must be loaded during boot-up with software provided by the manufacturer for infrared operation. the primary device must be properly configured with an infrared com port, irq level, and base address value. the infrared port must be installed and selected in the printers section of the windows control panel. software drivers the ir driver for windows 3.1 is available through hardcopy fulfillment. the driver shipped is proprietary to extended systems, inc. (esi) and is supported by hewlett-packard to the level of identifying the cause as the esi driver. beyond that, the call must be escalated to esi. the esi driver is not available through hps electronic fulfillment. the ir driver for windows 95 is the microsoft irda supported driver. it is available on the microsoft electronic bbs. after november 1995, machines manufactured with windows 95 will already have this driver installed. users must enable the ir port on the pc. the microsoft irda driver has a tray icon that provides status and run options. it is plug and play and polls the area for other ir devices within range. hewlett-packard recommends that users turn off plug and play and polling when not in use or not needed to prevent draining the battery. there is currently no ir support for macintosh products (october 96). hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 21 to print using the infrared port the infrared (ir) port on your hp laserjet 5p/5mp or 6p/6mp printer is located on the lower front left corner of the printer (figure 9). this port is compliant with the specifications determined by the infrared data association (irda). just above the port is a status light that indicates when the port is activated. to use the ir port, you need to use a portable device that also includes an irda-compliant ir port and be within the range of operation (see figure 10). the ir port is compatible with a wide variety of irda-compliant portable devices; however, the method for printing will vary depending on the type of device and the operating system in use. refer to the instruction manual for your portable equipment for specific instructions on printing from that device. 1. make sure the printer is in ready mode (the ready light is on). 2. align your laptop computer (or other portable equipment) that is equipped with an irda-compliant ir port within 3 feet (1 m) of the ir port on the printer and at an angle of 15 degrees to ensure printing (figure 10). 3. send the print job. the status light above the ir port turns on (printing a complex document or using a software print spooler on your pc may delay the time it takes for the ir status light to turn figure 9 irda port location (5p/5mp shown) hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 22 on). if the status light does not turn on, realign the port on your portable equipment with the port on the printer, resend the print job and stay within the range of operation during printing. 4. if you have to move the device, make sure you stay within the range of operation to maintain the connection. if the connection is interrupted before your print job is complete, the ir port status light will turn off. you have from 3 to 40 seconds (depending on the host implementation) to correct the interruption and continue the job. in this case, the ir port status light turns back on. 5. the connection can be permanently broken (interrupted for more than 3 to 40 seconds) if the sending ir port is moved out of the range of operation or if anything passes between the two ports to block the transmission, such as a hand or piece of paper, or even direct sunlight. in this case, the job needs to be reprinted. if you still have problems printing, make sure you are using an irda-compliant device and proper software and have selected the proper port for printing. see "infrared port not responding" on page 71. 30 1 meter 3 feet figure 10 irda port ranges (5p/5mp shown) hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 23 note the irda standard for infrared communications represents an emerging technology. older non-irda-compliant portable devices may not be compatible with your hp laserjet 5p/5mp, 6p/6mp printer. if you continue to have problems printing using the ir port, contact the manufacturer or dealer where you purchased your portable device to verify compatibility with the irda standard, and follow the troubleshooting procedure immediately following. troubleshooting ir printing problems ir printing problems may be caused by any of the several system components or by lack of proper configuration. the following checklist will help determine the source of the problem. 1. verify the user is operating the printer and pc as described in the users manual: less than one meter between devices, and not more than 15 degrees from direct center. 2. verify the host pc or laptop and the printer are irda-compliant and have the necessary hardware components for ir communication. 3. verify the ir software has been loaded on the primary device. (this is system software and should be available from the pc manufacturer.) 4. verify the host pc or laptop is properly configured. check the port assignment, the irq level, and the base address value. check both the dos autoexec.bat and config.sys files, and the windows system configuration. if all these elements are properly installed and configured, use the ir test tool to test the irda protocol transmission and device operation. this tool for troubleshooting ir communication problems, shown in figure 10, has been developed by genoa technology, inc., in cooperation with hewlett-packard. the part number is 5062-4661 and can be ordered through hp parts direct ordering. hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 24 the ir test tool can be used with any irda-compliant primary or secondary device, regardless of manufacturer. to test the peripheral device: 1. put the printer in ready mode. 2. press the "peripheral test" button on the test tool. the leds on the test tool will sequence. if the "pass" led lights, the test was successful, indicating that communication with the printers ir port is functioning normally. on hp laserjet printers, a self-test page will be initiated by the test. if the "test" led goes out and the "pass" led fails to light, the printers ir port is not functioning correctly; check the operators instructions included with the ir test tool. lb test connect pass peripheral test computer test test modes pcl printer postscript printer energy detect test frame switches ir diodes figure 11 infrared test tool hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 25 to test the host computer: 1. place the test tool on a table in front of the pcs ir port 2. press the "computer test" button. the test tool will sequence the leds. if the "pass" led light, the test was successful, indicating that communication with the printers ir port is functioning normally. if the "test" led goes out and the "pass" led fails to light, the hosts ir port is not functioning correctly. hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 26 interface connections your hp laserjet 5p/5mp, 6p/6mp printer supports the following interfaces (see figure 12): two ieee-1284Ccompliant parallel ports at the back of the printerone large b-type and one small c-type. one localtalk port at the back of the printer. one irda-compliant infrared port at the front of the printer. 1. localtalk cable and connectors. 2. ieee-1284 parallel cable and large (b-type) printer connector. 3. i eee-1284 parallel cable and small (c-type) printer connector. (the cable will be stamped as ieee- 1284 compatible. 4. host pc connector (a-type) (in the future c-type connectors may also be available on host pcs). caution make sure that all power and interface cables on your printer and host computer are properly grounded and in compliance with local electrical codes. figure 12 hp laserjet 5p/5mp, 6p/6mp printer interface connections hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 27 the parallel printer interfaces these interfaces are compliant with ieee-1284 specifications for "compatibility mode and nibble mode or hp bi-tronics. to use advanced interface functions, such as bi-directional communication, the parallel port on your host pc must also be ieee-1284 "nibble mode" compatible. the small c connector offers ieee-1284 ii (level 2) electrical interfacing, i.e. support for cables up to 10 meter length. the large "b" connector supports standard cable lengths up to 3 meters. the parallel interfaces can operate at speeds of up to 2 mbytes per second. use a high-quality, shielded ieee-1284 compliant parallel interface cable to insure best performance and support of advanced interface functions such as bi-directional communication. compliant cables are marked with ieee-1284" on the cable. applications such as the remote control panel, status monitor, or the status window use the printers parallel interface to send status information back to the computer (bi-directional communication). this requires a direct connection from the computer to the printer via a local parallel port (for example, lpt1:, lpt2:). these applications may not work through a network or a switching device. connecting to networks and switchboxes most devices connected between the printer and the host computer prevent the printer from sending data back to the computer. therefore, the remote control panel, status monitor, and status window may not work with networks, most hardware print spoolers, some software print spoolers, and some switchboxes. newer sharing devices are available that fully support status feedback. check with your supplier on support for bi-directional communication. automatic i/o switching the printer automatically switches between all interfaces (parallel, infrared, and localtalk) when multiple users share the printer. hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 28 resource saving resource saving gives the printer the ability to save certain entities such as permanent soft fonts, macros, symbol sets and user-defined graphics patterns when the printer changes personalities, resolutions or page protect modes. for example, if a user switches the printer from pcl mode to postscript mode, all pcl soft fonts and macros are lost. with resource saving, the hp laserjet 5p/5mp, 6p/6mp printer can retain these in memory. when the user switches back to pcl from postscript all of the pcl entities would still be resident in the hp laserjet 5p/5mp, 6p/6mp printer. resource saving can be changed via software, but can only be accessed when the printer has the postscript language installed and a minimum memory configuration of 7 mb. resource saving can be set via software for one of three modes, auto (default), on, and off. auto configuration sets the resource saving for pcl and postscript to a minimum value (400 kbytes) for each personality. setting resource saving to on allows the user to determine how much printer memory will be used for resource saving for the pcl personality and the postscript personality. the memory can be allocated in 100 kbytes increments. for example, if the user sets the resource saving memory size to 200 kbytes, a total of 400 kbytes of memory will be assigned to resource saving. 200 kbytes of memory will be used for postscript resource saving and 200 kbytes of memory will be used for pcl resource saving. turning resource saving off disables the resource saving function and no memory is allocated to resource saving. hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 29 i/o buffering i/o buffering allows the user to allocate printer memory to hold the job while it prints, freeing up the host system sooner, like a print spooler. the standard printer has approximately 10 kbytes of memory allocated to i/o buffering and an additional 100 kbytes of memory is assigned to i/o buffering for each mbytes of memory added to the printer. if the printer has a minimum of 6 mbytes of memory installed, the i/o buffer size can also be adjusted via software. three settings exist for the i/o buffer; auto (default), on, and off. auto sets the printers i/o buffer to a minimum value that is determined by the total amount of memory that is resident in the printer. setting i/o buffering to on allows the user to set the i/o buffer size setting the i/o buffering to off disables i/o buffering. note when you change the i/o buffer setting all downloaded resources are deleted. hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 30 reprinting jammed pages when a paper jam is cleared in the hp laserjet 5p printer and other previous hp laserjet printers, the printer will automatically reprint the page(s) that were jammed. the hp laserjet 6p printer will not do this by default with standard memory installed. the user must send the affected page(s) again from the host system to reprint them. if the user wishes the printer to reprint jammed pages automatically, the best solution is to add memory to the printer. if the user does not want to add memory but still wants jammed pages to reprint automatically, the reprint pjl variable should be changed from its default setting of auto to on. note if the reprint variable is turned on with only default memory installed in the hp laserjet 6p printer, the user may experience delays when printing multi-page jobs. these delays may substantially reduce the number of pages printed per minute. hp laserjet 5p/5mp, 6p/6mp printer service supplement new product features 31 service mode, pjl defaults the service mode should be used only by authorized service personnel. while in service mode, you can: print a service mode self test. verify and set the page count (the page count also is displayed on the standard self test). set the cold reset default. (this sets the factory default paper size to either letter or a4). set the demo page=true/false. used to remove the demo page option from the self test menu. set the diagnostic functions on or off (for software developers use only). since the hp laserjet 5p/5mp, 6p/6mp printer does not have a front control panel, service mode and many configuration tasks are accessible only through software (pjl commands). the following example shows how to use pjl commands to enter service mode and perform various service mode configuration tasks. note text is case-sensitive in pjl; enter exactly as shown. the e c symbol stands for the ascii escape character (esc or /027). when the pjl code is entered, print the data file (or use the dos copy command to copy it to the printer). detailed explanations of pjl commands and their functions can be found in the printer job language technical reference manual (hp part number 5961-0704). hp laserjet 5p/5mp, 6p/6mp printer service supplement service mode, pjl defaults 32 common pjl commands pjl command explanation e c %-12345x@pjl start pjl job. @pjl set servicemode=hpboiseid enter service mode @pjl set pages=0 set page count [= xxxxx] @pjl set crpaper=letter sets cold reset page size [= letter/a4] @pjl set skipdemo=false skips demo/pcl type page [= true/false] @pjl set diagnostics=off sets diagnostics [= off/on] (for isv use) @pjl set servicemode=exit exits service mode @pjl default paper=letter selects user paper size default @pjl reset performs pjl reset e c %-12345x exits pjl mode e c z prints self-test page e c e resets the printer. other pjl command examples: @pjl initialize sets user environment to factory defaults. @pjl set economode=on sets economode @pjl set pageprotect=legal sets the memory size for page protection to legal paper size. @pjl set manualfeed=on sets manual feed mode. @pjl set lang = french, german... sets the default display language 1 1 do not confuse this command with @pjl enter language, which sets the printer language to pcl or postscript. hp laserjet 5p/5mp, 6p/6mp printer service supplement service mode, pjl defaults 33 test pages and resets test pages, resets, and nvram initialization can all be performed by using the go and reset/job cancel buttons on the hp laserjet 5p/5mp, 6p/6mp printer status panel. table 2 shows how to perform these tests and diagnostic functions. function action result demo page press go button when printer is idle. prints page that highlights printer features and demonstrates print quality. self test press go and reset/job cancel buttons simultaneously. prints a self test page. continuous self test hold go button more than 20 seconds after powering on printer prints continuous self test pages. press the button to stop printing. reset (all i/o ) press reset button.

established or the transmission seems to be taking longer than usual. make sure the device you are using is irda-compliant; look for an irda symbol on the device or refer to the manual for the device for irda specifications. make sure that the operating system on your computer includes an ir driver and your application uses a hp laserjet 5p/5mp, 6p/6mp compatible printer driver. make sure you have positioned the device within the range of operation and that no objects, such as a finger, paper, books, or bright light, are interfering with the connection. also make sure the two ir ports are clean (free from dirt and grease). bright light of any kind (sunlight, incandescent light, fluorescent light, or light from an infrared remote control, such as those used for tvs and vcrs) shining directly into one of the ir ports may cause interference. position the device closer to the ir port on the printer. the printer prints only part of a page or document. the connection has been broken during transmission. if you move the portable device during transmission, the connection can be broken. irda-compliant devices are designed to recover from temporary connection interruptions. re-establish the connection (depending on the device you are using, you can have anywhere from 3 to 40 seconds to re-establish the connection). the print job has been properly sent to the printer, but the printer will not print. if the connection is broken before the entire print job has been transmitted to the printer (printing has not yet started), the printer may not print any of the job. if the data light is on, press the reset/job cancel button to clear the printers memory. then, position the device within the range of operation, and print the job again. the ir status light turns off during transmission. the connection may have been broken. if the data light is on, press the reset/job cancel button to clear the printers memory. then, position the device within the range of operation, and
