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 occasionally, especially when running a
long job. (No recovery steps are necessary.) If this condition occurs frequently, continue with
this RAP.
Initial Actions

• Ensure that the External Heat Roll Retract Sensor
Procedure
Close the Drawer. Cheat the Front Door Interlock. Switch on the power. The Heat Roll Heater
Rod illuminates after self-test completes.
Y N
Go to the OF10-3 Heat Roll AC Power
Enter dC330 010-031 Pressure Roll Heater Rod On. Press Start. The Pressure Roll Heater
Rod illuminates momentarily.
Y N
Go to the OF10-4 Pressure Roll AC Power
Enter dC330 010-029 External Heat Roll Lamp. Press 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).
Y N
Go to the OF10-5 External Heat Roll AC Power
Open the drawer. Remove the cheater on the Front Door Interlock. Measure the resistance
across the External Heat Roll Heater Rod ( P/J193-1 to P/J196-1). The resistance is less
than 10 Ohms.
Y N
Replace the External Heat Roll Heater Rod
Measure the resistance across the External Heat Roll Thermostat. The resistance is less
than 10 Ohms.
Y N
Replace the External Heat Roll Thermostat
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
8.6), or External Heat Roll Control Thermistor
• If no problem is found with the connectors, replace the SSR
• If the problem continues, replace the IOT Drive PWB
