Basic Operation
B802 30 SM
(while the original is still being scanned), to increase the copy speed. The original set
sensor monitors the stack of originals in the feeder, and detects when the trailing edge of

The skew correction sensor does not turn off even if the original was fed
by the maximum length of the or 150 mm after the skew
correction sensor turned on.
The registration sensor does not turn off even if the original was fed by
its length x 1.5 after the registration sensor turned on.
Sensor stays
on too long
The exit sensor does not turn off even if the original was fed by its
length x 1.5 after the exit sensor turned on.
The separation sensor does not turn on even if the original was fed by
transport path length x 1.5.
The skew correction sensor does not turn on even if the original was fed
by transport path length x 1.5.
The registration sensor does not turn on even if the original was fed by
transport path length x 1.5 after the skew correction sensor turned on.
Sensor does
not come on
