OF10-2 Fuser Oil Pump RAP
The Fuser Oil Pump is not dispensing Fuser Oil.
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 100
VAC is measured between P/J199-1 and P/J199-2 on the Fuser Oil Pump.
YN
Approximately 100 VAC is measured between P/
J1
8-3 and P/J18-1 on the AC
Driver PWB.
YN
Press St
op. +5.8 V
DC is measured between P/J11A-14 on the AC Driver PWB
and GND.
YN
+5 VDC is measured between P/
J1
9-1 and P/J19-7 on the AC Driver PWB.
YN
Go to Fl
ag 5 on
BSD 10.5 and check the harness for an open circuit. If the
harness is OK, replace the Distribution PWB (PL 9.3).
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 (PL 9.3).
Press Start. Th
e voltage at P/J11A-14 goes to less than +1.0 VDC.
YN
Replace the IOT Drive PWB (PL 9.
2)
Replace t
he AC Driver PWB (PL 9.3).
Go to Flag 3 on B
SD 10.5 and check the harness for an open circuit. If the harness is OK,
replace the Fuser Oil Pump (PL 8.7).
Replace the Fuser Oil Pump (PL 8.
7).
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 (PL 8.
1).
– Remove the Front Cover (PL 8.
1).
– Remove the Top Cover (PL 8.2).
•
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 is measured
between P/J100-4 on the SSR and P/J18-2 on the AC Driver PWB.
YN
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).
YN
ACH is measured between P/
J100-3 o
n the SSR and P/J15-1 on the AC Driver
PWB.
YN
ACH is measured between P/
J18-4 on
the AC Driver PWB and P/J15-1 on
the AC Driver PWB.
YN
Open the drawer. There is +24 VDC between P/
J11A-4
on the AC
Driver PWB and GND.
YN
Replace the AC Driver PWB (PL 9.3).
There is +24 VDC between P
/J419B-17 o
n the IOT Drive and GND.
YN
Go to F
lag 6 (Fl
ag 16 w/ Tag P31) on BSD 10.2 and check for an
open circuit.
Close the drawer. The voltage at P/J419B-
17 decreases to less than
+1.0 VDC.
YN
Replace the IOT Drive PWB (PL
9.
2).
Replace the AC Driver PWB (PL 9.3).
Go to Flag 15 (Fl
ag 26 w/ TAG P31) on BSD 10.2 and check for an open circuit.
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.
