Service Manual
Check for dirt or damage to the sensing contacts on
the right side of the cartridge assembly. Clean or
replace the PC drum unit if necessary. The toner
and PC drum unit must be installed as a unit.
Check the sensing contacts on the right side sub-
frame assembly. Clean or replace the affected right
side sub-frame.
If you still have the problem, replace the high
voltage unit 1(11G0326).
If you still have the problem, replace the high
voltage unit 2 (11G0313).
If you still have the problem, replace the printer
controller board (11G0324).
If the motor does not attempt to turn and you
receive a 910 error code, replace the driver 1 dc
motor (11G0256).
Be sure the toner and dc drum units are not
causing an overload on the dc motor.
If the motor turns but the paper carrying section of
the machine does not rotate, check the drive 1 unit
gear train for damage. Be sure the clutch on the
gear train engages for color printing. Replace the
drive 1 unit if necessary (11G0257).
If this does not correct the problem, replace the
printer controller board (11G0324).
