electronic
adjustment” on
page 3-8.
Turn the printer off.
Disconnect the printhead cables from J8 and J15 on the controller card.
Turn the printer on with the front door closed.
On the controller card, verify +5 V dc on pin 10 at J8 and +5 V dc on pins 1 and 2 at J15.
Verify grounds on pins 2, 4, and 7 at J8 and on pin 4 at J15.
• If voltages or grounds are incorrect, check the controller card. See “Controller card
service check” on page 2-17 for more information.
• If voltages are correct, 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.
