Description
Printing begins when the paper is in the wrong position.
Check and Cause
A defective feed sensor actuator can
cause incorrect timing.
4.4.2 JAM 0
Description
1. Paper has not exited from the cassette.
2. Jam-0 occurs if the paper feeds into the
printer.
Check and Cause
Check the solenoid by using Engine
Test Mode: Diagnostic Mode 0.
Check if the pad is loose due to bad
sealing of the side-pad.
Check the surface of the roller-pick-up

If continuous clusters occur, check

If the paper feeds into the printer and
