The paper feed clutch [A] is energized at the same time as the main motor
starts rotating. The main motor drive is transmitted to the paper feed clutch
gear [B] which controls the paper feed timing of the by-pass tray. When a
paper feed jam occurs, the paper feed clutch is de-energized and the misfed
paper can be removed by turning the manual paper feed knob.
The drive of the paper feed clutch for the by-pass table is also transmitted to
the LCT drive gears [C] through a timing belt [D].
The paper feed roller, separation roller, and the pick-up roller of the by-pass
feed tray are not interchangeable with those of the other trays of the copier
main body, because the paper feed direction (one-way clutch direction) is the
opposite.
