Transfer roll service check
Tray 2 service check
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.
FRU Action
Tray 2 Turn the printer off.
Separate the printer from Tray 2.
Turn the printer on and check the voltages on connector J28 on the controller board. See
the wiring diagram at the end of the service manual, or “Controller board connector pin
values” on page 3-2 for the J28 connector.
Pins 1, 4: 3.3 V
Pin 2: 24 V
Pin 6: Ground
If the voltages are incorrent, then replace the controller board. If the voltages are correct,
then try using Tray 2 again. If the printer error persists, then replace Tray 2.
