When the paper feed clutch [A] activates and the feed roller drive shaft [B]
rotates, the lever [C] rotates together with the shaft. However, the lever is
immediately stopped by the stopper [D].
After all paper is fed and the paper feed clutch turns off, the paper feed motor
still rotates to turn the separation roller [E] in the reverse direction. The
separation roller, still contacting the feed roller, turns the feed roller in the
reverse direction until the lever hits the rubber cushion [F].
By this feed roller reverse mechanism, the paper remaining in the gap
between the feed and the separation rollers returns 3 mm to the paper feed
tray.
After that, the separation roller solenoid turns off to move the separation roller
away from the feed roller. This releases the leading edge of the paper and
drops the paper to the paper feed tray.
This prevents remaining paper from being torn when the feed tray is drawn
out.
