Paper is fed by friction between the separation rollers [A] and the friction tab
[B].
Friction tab permit only the bottom sheet of the set of originals to be fed by
the separation rollers and the pick-up rollers [C] to the relay rollers [D].
The separation rollers have a built-in one-way gear. After the drive motor
stops, it continues to turn in the feed direction.
The friction tab is pressed against the separation rollers by springs [E]. To
prevent multi-feed, spring tension can be adjusted by two adjustment screws
[F] at the front and rear side of the tab holder.
The stopper [G] controls the gap between the friction tab and the separation
rollers to prevent a sheet of paper from being inserted deeper.
