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

–
Remove the Front Cover

–
Remove the Top Cover
(PL
8.2).
–
Ensure that connectors P/J422B, P/J193, P/J196, P/J105, and
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/J100-1
on the SSR and P/J15-1 on the AC Driver PWB (ACN into AC Driver PWB).

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.
