1. General Information

The Lexmark Z51 Color JetprinterTMis an electro-mechanical printer
that creates characters and graphics by composing programmed
patterns of ink dots using a printhead and liquid ink. The printhead
uses small heater plates and nozzles to control ink flow and the
formation of characters on the print media. The printhead assembly
and ink supply are combined into a single-unit, print cartridge,
available as a customer replaceable supply item. Dual printheads
provide color and true black printing without changing printheads.
The number and size of inkjets or n ozzles, in the printhead,
determines the overall quality and capability of the printer.The black
cartridge has a total of 208 nozzles and installs on the right. The
color cartridge has a total of 192 nozzles and installs on the left. The
printer is capable of printing in two directions from either cartridge.

Maintenance Approach

The diagnostic information in this manual leads you to the correct
field replaceable unit (FRU) or part. Use the symptom index, service
checks, and diagnostic aids to determine the symptom and repair
the failure. Begin with “Indicator Light Table” on page 2-1.

After you complete the repair, perform tests as needed to verify the
repair.

2. Diagnostic Information

Start

Service error indications are a series of Power light flashes. There is
a pause between each series of flashes. If your printer has an error
indicator, locate the series of flashes in the “Error Indicator Table”

on page 2-2. and take the indicated action. Unplug the printer to

clear the error indicator.
The printer also logs the last occurring error. If you think it may have

an intermittent error, or the error indicator lights have been cleared,
you can retrieve the error:

1. Run the“Print NVRAM Contents” on page 3-6 The last error
appears at the bottom of the page.

2. To capture the next error in the error log, run “Clear NVRAM”

on page 3-5 to clear the error.

3. Run the “Print Test Page” on page 3-2.” If no error appears,
go to “Power-On Self Test (POST) Sequence” on page 2-4.”

Maintenance Station Service Check

The maintenance station has three functions:

1. Wipes the printhead nozzles to clear them of dirt.

2. Provides a place for the printheads to spit all nozzles keeping
them clear prior to printing.

3. Seals the printheads when not in use to prevent the nozzles
from dr ying.

As the carrier moves to the right over the
maintenance station, a tab on the bottom of the
carrier engages a tab on the sled of the
maintenance station causing the caps to rise and
seal the printhead. Carrier movement to the left
uncaps the printheads. The wipers clean the
printhead nozzles as the carrier leaves the
maintenance station. The wipers clean the
printheads only when the carrier is moving to the
left. There should be no wiping action of the
printhead nozzles when the carrier is moving to
the right. After the printheads are wiped, a tab on
the carrier engages a tab on the maintenance
station and wipers are lowered. The carrier will
then move to the right over the felt pad where they
will spit all nozzles.

Paper Feed Service Check

If your printer does not have paper jam problems, continue with the
service check. If your pr inter does have a paper jam problems,
examine it for the following before you begin the service check:

• Check the entire paper path for obstructions.

• Be sure there is not too much paper in the sheet feeder.

• Be sure the correct type of paper is being used.

• Check for static in the paper.

FRU Action

1 SystemBoard With (J12) disconnected and power on, check for

+30 V dc between (J12-2) and ground at the

for motor pins shorted to the motor housing. If you
find a shorted pin, replace the motor. If you still
have a failure, replace the system board.

Diagnostic Information 2-11

2 Paper Feed Motor A noisy or chattering motor or a motor that fails to

turn, can be caused by:

• An open or short in the motor

• An open or short in the motor driver on the
system board

• A bind in the paper feed mechanism

With the paper feed motor cable disconnected
from the system board, check for 3 to 5 ohms
between pin 1 and 4 on the motor cable.

If the reading is incorrect, replace the motor.
Checkfor motor pins shorted to the motor housing.
If you find a shorted pin, replace the motor. If the
failure remains, replace the system board.

Although the paper feeds in a forward direction
only, the paper feed motor turns in two directions.
If the paper feed motor turns in one direction only,
replace the system board.

Binds in the paper feed motor or gear train can
cause intermittent false paper jams. Remove the

The auto compensator assembly is a paper pick device that
generates its own normal force which is inherent in the fundamental
design of the pick arm. If light media is used, the auto compensator
assembly picks very gently; if a heavy media is used, it picks very
aggressively.

The spring pressure of the device is designed so the input torque
from the motor causes downward force at the pick roll. The friction
between the pick roll and the paper produces a frictional locking
condition. The arm must pivot freely through its full range of motion.
If the pick assembly is noisy, replace the auto compensator
assembly.

4. Repair Information

This chapter explains how to make adjustments to the printer and
how to remove defective parts.

Note: Read the following before handling electronic parts.

Handling ESD-Sensitive Parts

Many electronic products use parts that are known to be sensitive to
electrostatic discharge (ESD). To prevent damage to ESD-sensitive
parts, follow the instructions below in addition to all the usual
precautions, such as turning off power before removing logic boards:

• Keep the ESD-sensitive part in its original shipping container (a

special “ESD bag”) until you are ready to install the part into the
machine.

• Make the least-possible movements with your body to prevent

an increase of static electricity from clothing fibers, carpets, and
furniture.

• Put the ESD wrist strap on your wrist. Connect the wrist band to

the system ground point. This discharges any static electricity in
your body to the machine.

• Hold the ESD-sensitive part by its edge; do not touch its pins. If

you are removing a pluggable module, use the correct tool.

• Do not place the ESD-sensitive part on the machine cover or on

a metal table; if you need to put down the ESD-sensitive part for
any reason, first put it into its special bag.

• Machine covers and metal tables are electrical grounds. They

increase the risk of damage because they make a discharge
path from your body through the ESD-sensitive part. (Large
metal objects can be discharge paths without being grounded.)

• Prevent ESD-sensitive parts from being accidentally touched by

other personnel. Install machine covers when you are not
working on the machine, and do not put unprotected ESD­sensitive parts on a table.

• If possible, keep all ESD-sensitive parts in a grounded metal

cabinet (case).

• BeextracarefulinworkingwithESD-sensitivepartswhencold

weather heating is used because low humidity increases static
electricity.

Adjustments

The user is directed, in the Printer Control program, to perform the
bidirectional alignment adjustments after replacing a print cartridge.

Removal Procedures

The following procedures are arranged according to the name of the
printer part discussed.

CAUTION: Unplug the power cord before removing any parts.

Releasing Plastic Latches

Many of the parts are held in place with plastic latches. The latches
break easily; release them carefully. Toremovesuch parts, press the
hook end of the latch away from the part to which it is latched.
