Step Actions and Questions
Check the Regi. Clutch (CLUTCH ASSY
13
DRV) for operation, and Regi Roll Assy
and Metal Regi Roll for rotation
First, start the Main Motor FULL2 test:
Service Mode > Engine Diag > Motor
Test > Main Motor FULL2,
the Regi Clutch test:
Engine Diag > Motor Test > Regi
Clutch.
Does the Regi. Clutch operate
properly, and do the Regi Roll Assy
and Metal Regi Roll rotate?
During this check, defeat the Front
Cover interlock switch (HARN ASSY
INTERLOCK).
Check the Regi Roll Actuator for shape
14
and operation
Are the shape and operation of the
Regi Roll Actuator normal?
15 Perform the Regi. Sensor test:
Mode > Engine Diag > Sensor Test >
Regi Sensor.
Does the number on the screen
increase by one, when the Regi Roll
Actuator is operated?
Check the connectors of the Manual
16
Feed No Paper Sensor (Photo Sensor)
for connection
Check the connections between the
MCU Board and Manual Feed No Paper
Sensor (Photo Sensor).
Are P/J23 and P/J233 connected
correctly?
Does the error still occur when
17
printing?
Check the Left Side Harness Assy for
18
continuity
Disconnect J23 from the MCU Board.
Disconnect J233 from the Manual
Feed No Paper Sensor (Photo Sensor).
Is each cable of J23 <=> J233
continuous?
19 Check the power to the Manual Feed
No Paper Sensor (Photo Sensor)
Disconnect J23 from the MCU Board.
Is the voltage across P23-6pin <=>
ground on the MCU Board, about +3.3
VDC?
