Infrared Communication
The HP LaserJet 5P and 5MP pri n ters ar e equ ipp e d with a n Infrared Datalink Association (IrDA) compliant port. The IrDA specification allows "wire less " tran smis sio n of pr int data be tw een a wide variety of hosts (primary) and peripheral (secondary) devices. A primary device -- suc h as a PC or laptop computer -- is capable of reading and writing data to anoth er primar y devic e or writing to a secondary device, such as a printe r. Secondar y dev ice s are read-only; they can n ot initiat e its own c ommun ic atio n, and ca n only respond to a host command when properly add ressed.
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 whe th er 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, softwar e,
or a combination of both. There are different LAP and LMP protocols for primary and secondary devices.
The HP LaserJet 5P printe r has th e comple t e second ar y pro toco l, 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 inte rn al IR port or an external IR accessory. Several manufacturers offer complete accessory upgrades for both host and peripheral devices.

To Print Us ing the Infrare d Port
The infrared (IR) port on your HP LaserJe t 5P or 5MP print er is located on the lower front left corner of the printer (Figure 8 ). This port is compliant with the specifications determine d 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 in clud es an IrDA-compliant IR port and be within the range of operatio n (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 establis he d, the status light comes on. If the conn e ctio n is br o ken or whe n the pr int jo b is complete, the status light goes off.
1. Make sure the printer is in Ready Mod e (the Ready light is on).
2. Align your lap top com pu ter (or o ther p or table 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 a n gle of ±15 degrees to ensure printing (Figure 9).
3. Send the print jo b. The st atus light above the IR port turns o n (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 wit h 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 operatio n to maintain t he 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 tu rns 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 piec e 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 a n 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-c om pliant p or table 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 Probl em s
IR printing problems may be caused by any of the several system components o r by lack of proper config ur at ion . The f ollo w in g checklist will help deter mine the sour ce of th e 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 communic ation.
8. Verify the IR software has been loaded on the primary device. (This is system software and sho uld be available f rom the PC manufacturer.)
9. Verify the host PC or laptop is properly conf igur ed. Chec k th e port assignment, the IRQ level, and the base address valu e. Check both the DOS AU TOEX EC. BAT and CONFI G. SYS files , and the Windows system configur atio n.

Interface Connections
Your HP LaserJet 5P or 5MP print er support s the follow ing interfaces (see Figure 11):
Two IEEE-1284–compliant parallel ports at the back of the
printer—one large B-type and on e small C-type.
One LocalTalk port at the back of the printer.
One IrDA-compliant infrared p or t at the fr on t of the printer.

The Parallel Printer Interfaces
These interfaces are compliant with IE EE- 1284 sp ecific atio ns f or "Compatibility Mode” and “Nibble Mod e” or “HP Bi-tronics ”. To use advanced interf ac e fu nc tio ns, such as bi-direc t ion a l communication, the paralle l port on your ho st PC mu st 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 interfac es can operate at speed s 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 mark ed with “IEEE-1284" on the cable.
Applications such as th e Remo t e Cont ro l Pan el, St atus Monito r, or the Status Window use the p r inte r ’s par alle l inte r f ac e to se nd status information back to the com pu ter (bi- dir e ctio n al 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 devic e.
Connecting to Networks and Switchb oxe s
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, so me software pr int sp o o le r s, and so me switchboxes. Newer sharing devices are available that fully support status feedback. Check with your supplier on support for bi-directiona l communication.
Automatic I/O Switching
The printer automatic ally switc he s be tween all interfac es (par alle l, infrared, and LocalTalk) when mult iple use rs share the pr inter.

Resource Saving
Resource Saving gives the printer the ability to save certain entities such as per m ane nt soft fonts , macros, symbol sets and user-defined grap hic s patt erns wh en the printer ch anges personalities, res olutio ns or p age prot ec t modes. Fo r examp le , 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 ent itie s wo uld st ill be r esident 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 conf igur at io n 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 print er memory will be used for Resource Saving for the PCL personality and the Postscript personality . The memory can be allo cat ed in 100 KByt es 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 soone r, 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 pr inte r .
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 buff er size Setting the I/O buffering to OFF disables I/O buffering .
Note
When you change the I/ O buf fer setting all downloaded resources are deleted.

2. Thermistor wire open. Remove the Fuser and measure the resistance between connectors J204-1
3. Thermal Fuse. Measure the continuity between connectors J103-1 and J103-2 on the Fuser
securely into the DC Controller PCA connectors (see Figure 6-29 in the Combined Service Manual for locations). Reseat the Fusing Assembly.
and J204-2 (see Figure 6-29 in the Combined Service Manual for location). Resistance should read approximately 440 K Ohms at 20 Deg C (room temperature). If the thermistor wire is open, replace the Fusing Assembly.
(see Figure 6-29, the Combined Service Manual for location). It should be approximately 30±5 Ohms for 100-120 VAC or 127±5 Ohms for 220-245 VAC. If the thermal fuse is open, replace the Fusing Assembly.

Infrared Port Not Responding
Situation Solution
The connection cannot be estab­lished or the transmission seems to be taking longer than usual.
The printer prints only part of a page or document.
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).

Troubleshooting
Situation Solution
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 lig ht is on, press the RESET button to clear the printer’s memory. Then, position the device within t he 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 button to clear the printer’s memory. Then, position the device within the range of operation, and print the job again.
Using the Infrared Test Tool
A special infrared troubleshooting test tool manufactured by Genoa Technolo gy , Inc . in cooper at ion with H ewle tt-Pac k ar d is available through HP Direct Ordering (part number 5062-4461). Refer to the discuss ion begin ning on pag e 22 for mor e inf o rmatio n.
