Transfer roll service check

Service tip: The transfer roll is 51.02 mm (2.009 inch) circumference. Any print quality problems such as lines
that are spaced 51.02 mm apart indicate you should check the transfer roll for damage and check for toner or
foreign material buildup.
Service tip: The transfer roll assembly is part of the maintenance kit and is replaced when an 80 Scheduled
Maintenance displays. Ask the customer if they have replaced the transfer roll recently.
CAUTION: Make sure the printer is unplugged before making any checks on the transfer roll or
associated parts for personal safety and to prevent damage to the printer.

Action
Check the transfer roll for toner buildup, surface damage to the roll,
oil, or other contaminants on the surface of the roll. Replace the
transfer roll as necessary.
Check the left transfer roll arm assembly to make sure it is fastened
and locked in the down position. If the arm is not locked down, make
sure the arm is not broken and locks into the EP frame correctly.
Check the left transfer arm assembly spring for proper operation.
Check the right transfer arm assembly to make sure it is fastened
and locked in the down position. If the arm is not locked down, make
sure the arm is not broken and locks into the EP frame correctly.
Check the right transfer arm assembly spring for proper operation.
For any background problems, ensure the contact to the HVPS board
is correct and that there is approximately 0 ohms resistance between
the transfer roll shaft and the HVPS contact. If correct, go to
quality—background" on page
Check the voltage at J15-3. The voltage changes from +24 V dc with
the printer idle to 0 V dc when the printer runs the print test. If the
voltage is incorrect, check the continuity of line J15-3 in the front
cable harness to the HVPS. If there is no continuity, replace the cable
harness. If there is continuity, replace the HVPS. If the problem
continues, replace the system board.
