10-900 Fuser Cycle Down RAP
The Fuser temperature fell below the normal value during the job. The machine cycled down
and temporarily stopped the copying job; and when it reached the operating temperature, can-
celed the above condition and started again automatically (the job resumes).
NOTE: This condition should be expected to happen oc
casionally,
especially when running a
long job. (No recovery steps are necessary.) If this condition occurs frequently, continue with
this RAP.
Initial Actions
• Refer to BSD 10.2, 10.3 and 10.12 for the following procedure.
• Ensure that the External Heat Roll Retract Sensor (PL 8.4) is f
ully seated.
Procedure
Close the Drawer. Cheat the Front Door Interlock. Switch on the power. The Heat Roll Heater
Rod illuminates after self-test completes.
YN
Go to the OF
10-3 Heat Roll A
C Power RAP.
Enter dC330 010-031 Pressure Roll Heater Rod On. Pre
ss Start. The Pressure Roll Heater
Rod illuminates momentarily.
YN
Go to the OF
10-4 Pr
essure Roll AC Power RAP.
Enter dC330 010-029 External Heat Roll Lamp. Pre
ss Start. ACH is measured momen-
tarily between P/J100-
1 on the SSR and P/J15-1 on the AC Driver PWB (ACN into AC
Driver PWB).
YN
Go to the OF
10-5 Ex
ternal Heat Roll AC Power RAP.
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:
• Disconnect the connectors to the Heat Roll, Pressure Roll, and External Heat Roll Ther-
mostats; AC Driver PWB; SSR; and the IOT Drive PWB. Check for broken, bent, or dirty
pins. Disconnect
/reconnect the connectors several times to remove oxidation.
• Check the Heat Roll Control Thermistor (PL 8.4),
Pressure Roll Control Thermistor (PL
8.6), or External Heat Roll Control Thermistor (PL 8.8). Replace if worn, or dirty.
• If no problem is found with the connectors, replace the SSR (PL 9.3).
•
If the problem continues, replace the IOT Drive PWB (PL 9.
2).
OF10-1 OCT Detection Failure RAP
The system does not detect an OCT when one is installed.
Initial Actions
Refer to BSD 10.11 for the following procedure.
Procedure
Enter dC330 010-296 OCT Detect. The display indicates L.
YN
Go to Fl
ag 7 and Fl
ag 8 on BSD 10.11. Check the harness for an open circuit. If the har-
ness is good, replace the IOT Drive PWB (PL 9.
2).
Replace the IOT Drive PWB (PL 9.2).
