CHK>MTR in service mode. Does the
cartridge inside toner feeder motor rotate?
2 Execute COPIER>FUNCTION>PART-
CHK>MTR in service mode to operate
the hopper motor. Is the voltage between
J512-B4 (+) and J512-B5 (-) on the DC

1 Execute COPIER>FUNCTION>PART-
CHK>MTR in service mode. Does the
hopper inside toner feeder motor rotate?
2 Execute COPIER>FUNCTION>PART-
CHK>MTR in service mode to operate
the hopper inside toner feeder motor. Is
the voltage between J504-B18 (+) and
J504-B19 (-) on the DC controller PCB
about 24 V?
1 Open the front door, and release the
fixing/feeding assembly. Are the ends of
the drum warm? (Do not touch the surface
of the drum.)
2 Set the meter range to 12 VDC, and
connect the probes to J505-A8 (+) and
J505-A7 (-) on the DC controller PCB. Is
the voltage between the terminals 5 V
during standby?
3 Replace the heater driver PCB. Is the
problem corrected?
4 Remove the drum, and set the meter range
to 'W × 1'. Does the index of the meter
swing when ht probes are connected to
both terminals?
