4. Check if the dog-eared
paper, under-curled
paper, or the paper fed
in a wrong timing is
disturbed at the cursor
and causing a sluck
jam.
Replace the cursor with a new type.
5. Check if a slack jam
and stapling problem
has occurred while the
paper entered the DF
process tray due to the
down-curl of the paper
at duplex printing since
the paper approaches
the process tray.
If correcting dog-ears or curlings is not possible,
apply two seats of film onto the plastic guides to
support the paper ends during feeding.
6. With stapling at one
point with about 65
sheets, check for the
failure on the bundle
when it is delivered in
the shape of an arc.
1. If a wire from the ejection motor is pinched by
other component or a connector is loosely
connected, correct.
If a loss of synchronism is observed with the
ejection motor due to lack of torque, replace the
motor.
2. If paper slippage occurs due to the lack of
pressure by the ejection rollers, check if the
pressure sufficient (3 springs, at the center).
If a malfunction to encumber the ejection rollers
to generate pressure is observed, correct.
7. With stapling set at 2
points and about 50
sheets, run a test print
and check the print
bundle delivered for the
failure on the direction
of ejection and the front
and back side, abrupt
alignment, and overall
alignment.
If the paper is curled, change the direction of loading
paper or replace the paper.
