Initial Actions
Refer to BSD 10.5 and 10.12 for the following procedure.
Procedure
Enter dC330 010-033 Oil Pump. Press Start and Stop several times. Approximately
VAC is measured between P/J199-1 and P/J199-2 on the Fuser Oil Pump.
Y N
Approximately 100 VAC is measured between P/J18-3 and P/J18-1 on the AC
Driver PWB.
Y N
Press Stop. +5.8 VDC is measured between P/J11A-14 on the AC Driver PWB
and GND.
Y N
+5 VDC is measured between P/J19-1 and P/J19-7 on the AC Driver PWB.
Y N
Go to Flag 5 on BSD 10.5 and check the harness for an open circuit. If the
harness is OK, replace the Distribution PWB
Go to Flag 4 on BSD 10.5 and check the harness for an open circuit. If the har-
ness is OK, replace the AC Driver PWB
Press Start. The voltage at P/J11A-14 goes to less than +1.0 VDC.
Y N
Replace the IOT Drive PWB
Replace the AC Driver PWB (PL
Go to Flag 3 on BSD 10.5 and check the harness for an open circuit. If the harness is OK,

OF10-3 Heat Roll AC Power RAP

Initial Actions
Refer to BSD 10.2 and 10.12 for the following procedure.
• Open the Drawer and extend it to the service position. Perform the following:
– Remove the Oil Cartridge
– Remove the Front Cover
100 – Remove the Top Cover
• Ensure that connectors P/J422B, P/J419B, P/J194, P/J191, P/J105, P/J100, P/J11A,
and P/J18 are seated correctly on the IOT Drive PWB, AC Driver PWB, SSR, Heat Roll
Thermostat, and the Heat Roll Heater Rod and there are no obvious crimped or broken
wires.
Procedure
Close the Drawer. Cheat the Front Door Interlock. Switch on the power. ACH
between P/J100-4 on the SSR and P/J18-2 on the AC Driver PWB.
Y N
ACH is measured between P/J100-4 on the SSR and P/J15-1 on the AC Driver PWB
(ACN into the AC Driver PWB).
Y N
ACH is measured between P/J100-3 on the SSR and P/J15-1 on the AC Driver
PWB.
Y N
ACH is measured between P/J18-4 on the AC Driver PWB and P/J15-1 on
the AC Driver PWB.
Y N
Open the drawer. There is +24 VDC between
Driver PWB and GND.
Y N
Replace the AC Driver PWB
There is +24 VDC between P/J419B-17 on the IOT Drive and GND.
Y N
Go to
open circuit.
Close the drawer. The voltage at P/J419B-17 decreases to less than
+1.0 VDC.
Y N
Replace the IOT Drive PWB
Replace the AC Driver PWB
Go to Flag 15 (Flag 26
If TAG P31 is present, replace the Varistor PWB if the problem persists.
There is +5 VDC between P/J105-1 on the SSR and GND.
