The leading edge of the paper is not turned ON (blocked) the registration sensor (PS9) even after
the lapse of a given period of time after a duplex paper feed sequence has been started.
92-02
After the start of the second-side feed of paper in the duplex mode, loop forming has not been
complete before the second side of a sheet enters the registration roller because the rise timing of
load to perform registration is earlier than the rise timing of load to form a loop.
92-03
For the second-side feed of paper in the duplex mode, the image write start signal permit continues
to be disabled for a predetermined period of time after the timing of the image write start signal
output.
92-04
The leading edge of the paper is not turned OFF (blocked) the ADU transport sensor (PS11) even
after the lapse of a given period of time after a duplex paper feed sequence has been started.

Paper jam of a sheet of paper left at the duplex pre-registration section results, if a sheet of paper is
determined to exist at a position detected when the main power switch is turned ON, a door is
opened and closed, or a misfeed or malfunction is reset.

The leading edge of the paper is not turned ON (unblocked) the ADU transport sensor (PS11) even
after the lapse of a given period of time after the paper has turned OFF (blocked) the paper exit
sensor (PS13).
