Paper Movement Overview
The paper feed system picks print media automatically from the paper cassette or accepts it from the manual feed slot 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 6 shows the possible paper paths and locations of the various solenoids, photosensors and rollers.

Infrared Communication
The HP LaserJet 5P and 5MP 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 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 · The Link Access Protocol (LAP) layer controls the physical
device for sending and receiving the data. 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.

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).
Figure 8
IrDA Port Location
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
20
HP LaserJet 5P Printer Service Supplement New Product Features
(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.

HP LaserJet 5P Printer Service Supplement New Product Features
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.
22
HP LaserJet 5P Printer Service Supplement New Product Features
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.

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.

Interface Connections
Your HP LaserJet 5P or 5MP printer supports the following interfaces (see Figure 11):
· Two IEEE-1284compliant 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. IEEE-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.
25
HP LaserJet 5P Printer Service Supplement New Product Features
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
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.

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.

Error 53 -- Memory/SIMM Errors
Error 53 is indicated by a combination of the Error LED and either Tray LED, on and steady. More detail about the error is found by pressing the GO and RESET buttons simultaneously, which causes a secondary sequence of light patterns. These secondary patterns form a binary representation of the exact hardware type, device and error number in the form 53-XY-ZZ as shown in Table 4. Table 4. Memory Error Codes
X-Hardware Type 0: ROM 1: RAM 0: 1: 2: 3:

Figure 27 explains how to read the light sequences. The initial sequence (Part 1) shows that ERROR 53 can be indicated by two different light sequences, depending on the X value: ROM (x =0) or in RAM (x =1) . Pressing GO and RESET together produces a secondary light pattern, which reveals the Y- and ZZ- values, which complete the error code (Part II) . The binary Y value is read from the top two LEDS; the binary Z value is read from the lower three LEDS. Part III of Figure 27 shows the binary values of the different light combinations.

Infrared Port Not Responding
Situation The connection cannot be established or the transmission seems to be taking longer than usual. Solution Make sure the device you are using is IrDAcompliant; 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 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 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 reestablish the connection).
The printer prints only part of a page or document.
65
HP LaserJet 5P Printer Service Supplement Troubleshooting
Situation The print job has been properly sent to the printer, but the printer will not print.
Solution
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 button to clear the printer's memory. Then, position the device within the range of operation, and print the job again. The IR status light turns off during The connection may have been broken. If the transmission. Data light is on, press the RESET button to clear the printer's memory.

The figures in this section illustrate the major subassemblies in the printer and their component parts. A table (material list) follows each exploded assembly diagram. Each table lists the reference designator (item number) for each part, the associated part number for the item, the quantity, and a description of the part. While looking for a part number, pay careful attention to the voltage listed in the description column to ensure that the part number selected is for the correct model of printer.
