then return to this check.

6 Paper Feed Ink smudging and smearing can be caused by

paper problems or problems in the paper feed
area.

Check the following:

• Correct type of paper is being used. Also check
the paper for curl or wrinkles.

• Feed rollers for wear, dirt, or looseness.

• Gears for wear or binds.

• Paper path for obstructions.

7 Carrier Transport Blurred print and voids can be caused by problems

in the carrier transport area. Check the following:

• Carrier transport belt for wear.

• Carrier guide rod for wear or dirt. If dirty, clean
and lubricate.

• Carrier to carrier frame engagement should be
lubricated with grease P/N 1329301.

• Idler pulley parts for wear, damage, or

Test Page

This test prints the test page.
To run a complete test page of black and color patterns, be sure the

print cartridges are in good condition.
To enter the test:
Move the carr ier to the far left, before turning the printer on
The test page prints the following lines:
Line 1 - Code level and date.

Line 2 - Manufacturer name.
Line 3 - Model name.
Line 4 - Motor type.
The next line is the black print cartridge nozzle pattern. The next

three lines are the purge pattern where all nozzles are printing. This
action cleans (purges) the nozzles. Another nozzle test pattern
follows.

These test patterns are used to verify all print cartridge nozzles are
working. There should be no breaks in the diagonal line. A break in
the diagonal line indicates one or more nozzles are not working.

Diagnostic Aids 3-1

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 sensitiveto
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:

• Keepthe 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 connector shroud (cover); 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 coversand 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 ESD-sensitive parts on a table.

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

(case).

• Be extra careful in working with ESD-sensitiveparts when cold weather

heating is used because low humidity increases static electricity.

Repair Information 4-1

4091-001

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. Toremove such parts, press the
hook end of the latch away from the part to which it is latched.
