Step Checks
1 Does the drum motor rotate during
initial rotation?
2 Does the drum motor start to but
fail to rotate during initial rotation?
3 Set the meter range to 5 VDC, and
measure the voltage between
J1026-A12 (+; DRMON) and
J1026-A13 (-; GND) on the DC
driver PCB.
Does it change from about 0 to
about 5 V when the power switch
is turned off and then on and the
drum motor starts to rotate?
4 Is there 24 V between J372-1
and -2 of the drum motor?
5 Set the meter range to 5 VDC, and
measure the voltage between
J1026-A3 (+; DRMRDY) and
J1026-A13 (-; GND) on the DC
drum PCB.
Does it change from about 0 to
about 5 V when the power switch
is turned off and then on and the
drum motor starts to rotate?

YES Check the
photosensitive drum and
the transfer drum for
overload.
YES Check the wiring from
J1026 to the drum
motor; if normal, replace
the drum motor.
NO Check the voltage
between J935-1 and -2
on the DC fuse PCB; if
not 24 V, replace the DC
fuse PCB.
YES Replace the DC driver
PCB or the CPU PCB.
(After replacement,
execute the work under
II. H. 10. or II. H. 1.)
NO Check the wiring from
J1026 to the drum
