12.2 TWO-SIDED ORIGINAL FEED (AUTO REVERSE) MODE
Unlike for one-sided original feed, the back side of the original must be
copied first to keep the originals and copies in the correct order.
During original feed-in, the sequence is the same as for one-sided feed;
however, the belt drive motor continues rotating until the original reaches the
inverter section. The DJF CPU also energizes the feed-out motor and the
inverter solenoid [A] for a short time to lift the inverter pawls [B].
After the inverter mechanism inverts the original (10 pulses after the feed-out
sensor [C] activates), the belt drive motor reverses and the original is fed
towards the original scale. It is stopped at the correct position on the
exposure glass, and the DJF CPU sends the copy start signal.
When the scanner reaches the return position, the copier’s CPU sends the
invert original signal to the DJF CPU in order to make a copy of the front
side. The original is inverted in the same way as for the back side, as
explained above.
