Cause
Feed pressure is weak.
Feed pressure is strong.
Amount of buckle for
registration is not
correct.
The position of
registration is not
correct.
The retry mode for paper
feed is ON.
(Even though registration
sensor does not turn on,
it will not jam. The drum
will rotate one more time,
and paper will be fed.)

Solution
Feed pressure is set for thick paper.
( O/I Operation - Printing on thick
or thin)
Separation pressure is set for weak.
( S/M 6.7.3)
Separation pressure is set for weak.
( S/M 6.7.3)
Replace the friction pad.
＊Use the side fence friction pads if
multiple sheet feeding occurs after
the friction pad has been changed.
Adjust SP6-20 (the amount of
buckle for registration). (
5.7.6)
Increase the value: The occurrence
of paper skew will be reduced, but
the paper is more likely to slip and
the registration position may be
incorrect.
Decrease the value: The paper
registration position will be correct.
Caution: Once this has been
changed, the registration position
will be out of order.
Adjust SP6-21 (the paper
registration position).
( S/M 5.7.3)
C249/C264: Adjust SP6-100 to 107
(paper registration - each speed)
C238: Adjust SP6-23 (paper
registration - each speed)
( RTB# RC238008a)
C238: SP6-33 (paper registration -
each speed, when image shifts
forward)
SP6-34 (paper registration - each
speed, when image shifts
backward)
( RTB# RC238011d)
Turn off SP2-33 (Re feeding
setting). ( RTB #RC238008)
( S/M 5.3.6)
Caution: A jam might occur after
you turn the machine off.
