10-355 External Heat Roll Contact Failure RAP
The External Heat Roll Retract Sensor did not go L within 5 seconds after the External Heat
Roll Retract Motor started rotating.
Initial Actions
Refer to BSD 10.6 and 10.12 for the following procedure.
Perform the following:
1.
Open the Drawer
2.
Remove the Oil Cartridge
(PL
8.1)
3.
Remove the Front Cover
(PL
8.1)
4.
Remove the Top Cover
(PL
8.2)
5.
Close the Drawer.
6.
Switch the power off, then on.
Procedure
NOTE: When using component control to energize the External Heat Roll Retract Motor, the
following conditions occur:
•
When the code[10-027] (contact) is first entered, the motor will drive until the External
Heat Roll Retract Sensor senses that the External Heat Roll is in the contact position.
Then the code switches to off.
•
Subsequent attempts to enter [10-027] have no effect. In order to test code [10-027]
again, code [10-028] (retract) must be entered first in order to drive the External Heat Roll
to the retracted position.
Enter dC330
010-027 External Heat Roll Retract Motor

good, replace the External Heat Roll Retract Motor
NOTE: In the next step, the drop in voltage may be momentary or may be for a longer
duration, but a drop in voltage should occur.
Press Start. The voltage at P/J413A-1 drops to less than +20.0 VDC.

Check the following:
•
The actuator for the External Heat Roll Retract Sensor
•
Go to

on BSD 10.6 and check the harness for an open circuit.
•
Go to
Flag 2
on BSD 10.6 and check the harness for an open or short circuit.
•
If the harness is good, replace the External Heat Roll Retract Sensor
Check the following:
•
Missing and/or broken External Heat Roll Retract Motor gear
•
Binding in the linkage of the contact/retract mechanism for the External Heat Roll
•
Loose connectors and pins for the External Heat Roll Retract Motor and Sensor
