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.

	FRU	Action
1	Transfer roll assembly	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.
2	Left transfer arm assembly	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.
3	Right transfer arm	Check the right transfer arm assembly to make sure it is fastened and
	assembly	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 “Print
		quality—background” on page 2-118.
4	HVPS—917 Error code	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.
