multiple sheet feeding occurs even
if the friction pad has been
changed.
Adjust SP6-20 (the amount of
buckle for registration). (! 5.7.5,
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). (! 5.7.3)
Turn off SP2-33 (Re feeding
