Overview
Overview
The HP LaserJet 5P and 5MP pfinters (HP Product Numbers
C3150A and C3155A) have many service and repair processes in
common with their predecessors, the HP LaserJet 4L/4ML and
4P/4MP printers. These processes are documented in the
Combined Service Manual for the HP LaserJet 4L14ML
(C2003A /C2015A) HP LaserJet 4P14MP (C2006A /C2040A). The
purpose of this appendix is to provide supplemental service

The HP LaserJet 5P/5MP Status Panel
This HP LaserJet printer has been designed to be controlled
mainly by software. However, some simple functions are also
available from the status panel. You also receive status
information about the operation of the IrDA-compatible infrared
(IR) port from the status light just above the port (for more
information, see “To Print Using the Infrared Port,” later in this
appendix).

displaying an amber or a green hue and flashing individually or
sequentially as a group (cascading).
The status light above the IR port indicates tlhe current status of
the IR port by displaying a green hue. This status light comes on
only when the IR port is being used—the Status Panel lights
operate the same for the IR port as they do for any other port on
the printer.
ERROR (amber)

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.

Infkared 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
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 Mana~ement Protocol (LMP) laver routes data to and
from the host o~erating system (DOSfii~dows).
The data flow is shown in Figure 7.
The LAY 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 prirmwy 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 de~ermined 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
The IR port is compatible with a wide variety of IrDA-cornpliant
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 j ob 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

(1 m) of the IR port on the printer and at an angle of *1 5
degrees to ensure printing (Figure 9).
Send the print job. The status light above the IR port turns on
3.
(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.
If you have to move the device, for example, to add paper, make
4.
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 (interruptec[ for
more than 3 to 40 seconds) if the “sendin< IR port is moved out
of the range of operation or if anything passes between the two
ports to b~ock the transmission, such &-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 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 verifj compatibility with
the IrDA standard, and follow the
troubleshooting procedure immediately
following.
Troubleshooting IR Printing Problems
IR printing problems maybe caused by any of the several system
components or by lack of proper conf@u-ation. The following
checklist will help determine the source of the problem.
Verify the user is operating the printer and PC as described in
6.
the User’s Manual: less than one meter between devices, and
not more than *15 degrees from direct center.
Verify the host PC or laptop and the printer are IrDA-compliant
7.
and have the necessary hardware components for IR
communication.
Verify the IR software has been loaded on the primary device.
8.
(This is system software and should be available from the PC
manufacturer. )
Verify the host PC or laptop is properly configured. Check the
9.
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.
