3. Re-Pickup (cassette pickup)
If the vertical path roller paper sensor (PS4) does not detect copy paper within a specific period
of time after the cassette pickup roller has started to rotate, the pickup roller is rotated once again to
execute pickup operation, thereby ensuring correct pickup (as for recycled paper).
If the vertical path roller paper sensor does not detect copy paper after re-pickup, the machine
will assume the absence of copy paper and will indicate “ ” in the count/ratio indicator in the
control panel. (This mechanism substitutes a paper detecting mechanism.)
I: Re-pickup operation is executed if the vertical path roller paper sensor (PS4) does not detect
copy paper within 0.5 sec after the pickup clutch solenoid (SL1) has turned don.
II: The cassette pickup solenoid (SL5) turns on once again about 1.3 sec after the pickup clutch
solenoid (SL1) turns on.
