4.8 TWO-SIDED ORIGINAL FEED MECHANISM

Unlike 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 DF 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, 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 DF CPU sends the copy start

signal.

When the scanner reaches the return position, the copier’s CPU sends the

invert original signal to the DF CPU in order to make a copy of the front side.

The original is inverted in the same way as for copying the back side, as

explained earlier on this page.
