Procedure

Close the Feeder Top Cover. The problem continues.

Y N

Adjust or repair the Feeder Top Cover latch. (REP 13.4.1)

Replave the Feeder Top Cover Switch. (PL 13.9)

At power on, the control logic detected either the Platen Interlock is close when the Feeder

Cover is open or the Feeder Cover Interlock is close when the Platen Interlock is open.

Procedure

If this occurs frequently, confirm if there is any interferance with the Feed Sensor ( PL 13.9),

the Document Registration Sensor (PL 13.7) or the Exit/Invert Sensor (PL 13.7). Check the

sensor connectors for prober connection. Replace one sensor at a time until the problem is

solved.
