There is a misfeed at the 2nd transfer section. The paper does not unblock the Registration Sensor
(PC1) even after the lapse of a predetermined period of
time after the Registration Roller Solenoid (SL2) has
been de-energized.
The Fusing Paper Loop Sensor (PC8) is not blocked by
the paper that has moved past the position, at which the
sensor is blocked.
Detection of paper left in 2nd transfer

The Registration Sensor (PC1) is blocked when the
Power Switch is turned ON, a cover is opened and
closed, or a misfeed or malfunction is reset.
The Fusing Paper Loop Sensor (PC8) is blocked when
