Bin unit

2.4 Tamper drive

The tampers in the bin unit are driven by the tamper drive motor located on the
lower frame of the sorter. The tampers jog each time a copy is fed into a bin and
keeps the copies in each bin evenly stacked.
(1) The copier begins feeding paper when the "Print" key is pressed. Copies
discharged into each bin are stacked evenly by the movement of the tampers
in the bin unit.
(2) The tampers are driven by the tamper motor (M3). The amount of motion of
tamper (front) is constant, regardless of paper size, while that of the tamper
(rear) are determined by the paper size signal supplied from the copier.
(3) The tamper home position is detected by tamper home position sensor.
