FRU

Action

Printhead

Note:

New printhead

must be aligned. See

“Printhead assembly
electronic
adjustment” on
page 3-38

Turn the printer off.

Disconnect the printhead cables from J9 and J6 on the controller board.

Turn the printer on with the front door closed.

On the controller board, 5 V dc on pins 2 and 3 at J6 and +5 V dc on pins 1,and 10
at J9.

Verify grounds on pins 4, 5, 6, and 7 at J6 and on pin 4 at J9.

• If voltages or grounds are incorrect, then check the controller board. See

“Controller

board service check” on page 2-35

for more information.

• If voltages are correct, then replace the printhead (comes with cables).

FRU

Action

Transfer roll

Note:

Do not touch the transfer roll except at its ends. Place a sheet of paper over the roll to

prevent damage from finger oils or hand lotion.

Check the springs in the left and right transfer roll bearings. Do not try to move the left
spring. The bearing assemblies should support the transfer roll, applying evenly distributed
forces to the PC drum.

Replace the transfer roll assembly if the springs or bearings show signs of damage, or
fatigue.

Inspect the transfer roll for signs of wear, damage or contamination.

Replace as necessary.
