10-379 Power On External Heat Roll Not Ready RAP
The External Heat Roll did not reach the Ready temperature within 5 minutes after Power On.
Initial Actions
Refer to BSD 10.2, 10.3, 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/J
422B, P/J193, P/J196, P/J105, and P/J100 are seated
correctly on the IOT Drive PWB, AC Driver PWB, SSR, Heat Roll Thermostat, and
the External 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. Enter dC330 010-029
External Heat Roll Lamp. Press Start. ACH is measured momentarily between P/J
100-1
on the SSR and P/J15-1 on the AC Driver PWB (ACN into AC Driver PWB).
YN
There is +5 VDC between P
/J105
-1 on the SSR and GND.
YN
There is +5 VDC between P
/J422B-
3 on the IOT Drive PWB and GND.
YN
Replace the IOT Drive PWB (PL 9.
2).
Go
to Flag 1 on BSD
10.3 and check the harness for an open circuit. If the harness is
good, replace the IOT Drive PWB (PL 9.2).
There is +4.5 VDC between P/J105-2 on
the IOT Drive PWB and GND
YN
Replace the SSR (PL 9.3).
Press Start. Th
e voltage at P/J105-2 decreases momentarily to less than +1.0 VDC.
YN
Replace the IOT Drive PWB (PL 9.
2).
Go
to Flag 1 on BS
D 10.3 and check the harness for an open circuit. If the harness is
good, replace the SSR (PL 9.3).
Open the drawer. Remove the cheater on the Front Door Interlock. Measure the resistance
across t
he External Heat Roll Heater Rod ( P/J193-1 to P/J196-1). The resistance is less
than 10 O
hms.
YN
Replace the External Heat Roll Heater Rod (PL 8.8).
Measure the resistance across the External Heat Roll Thermostat. The resistance is less
th
an 10 O
hms.
YN
Replace the External Heat Roll Thermostat (PL 8.
8).
Check the following:
•Go to Flag 2 on
BSD 10.3 and check the harness for an open circuit.
•Go to Flag 3 on
BSD 10.3 and check the harness for an open circuit.
• If the harness is good, go to Flag 14 on B
SD 10.2 and check the harness for an open cir-
cuit.
• Disconnect the connectors to the components (External Heat Rol
l Thermostat, AC Driver
PWB, SSR, and the IOT Drive PWB). Check the connectors for broken, bent, or dirty pins.
Disconnect, then reconnect, the connectors several times to remove contaminants due to
oxidation.
• Check the External Heat Roll Control Thermistor (PL
8.
8). Replace the Thermistor if worn,
or dirty.
• Check the Drawer connector P700B at
the rear of the Fuser for damaged pins.
• Ensure that NVM location 777-003 External Heat Roll Temperature Control = 178
(NASG
), 193 (ESG) and NVM location 777-012 External Heat Roll Ready Temperature =
165 (NASG), 188 (ESG).
• Replace the SSR (PL 9.3)
if
no problems is found with the connectors.
• If the problem continues, replace the I
OT Drive PWB (PL 9.2).
