Step Check
Check of ROLLER ASSY DUP, ROLLER
9
ASSY DUP OUT and ROLL PINCH DUP
Open Duplex.
Are ROLLER ASSY DUP, ROLLER ASSY
DUP OUT, and ROLL PINCH DUP attached
correctly?
Also, do these parts rotate smoothly without
any dirt or damage?
Turn by hand to check.
Does the error recur when a test print is
10
made in the duplex mode?
Check of transmission of drive force to
11
ROLLER ASSY DUP
Open Duplex.
Remove COVER-L DUP. (p.414)
Are all gears that transmit rotation of MOTOR
ASSY DUP (Lower Roll Motor) to ROLLER
ASSY DUP turning smoothly?
Turn gears by hand to check.
Check after replacement of MOTOR ASSY
12
DUP (Lower Roll Motor)
Replace MOTOR ASSY DUP.
