The registration ON/OFF check is the same as for one-sided originals. The
inverter motor and the inverter solenoid turn on 100 milliseconds after the
registration sensor turns off. If the feed-out sensor is not actuated within
1,250 milliseconds after the feed-out motor starts turning, the Original
Misfeed indicator lights (ON check). The Original Misfeed indicator also lights
if the feed-out sensor does not turn off within 1,250 milliseconds after the belt
drive motor reverses (OFF check).
If a previous original remains on the exposure glass after manual copying
and DF feed is attempted, the original misfeed indicator lights. When the DF
is lifted and the previous original is removed, DF copying is permitted.
