In the sort/stack mode, the shift roller [A] moves from side to side to separate the
sets of copies.
The horizontal position of the shift roller is controlled by the shift motor [B] and the
shift gear disk [C]. After the trailing edge of the copy passes the upper transport
roller, the shift motor turns on, driving the shift gear disk and the link [D].
After the paper is delivered to the lower tray [E], the shift roller moves to its home
position, which is detected by the shift HP sensor [F]. Then, when the trailing edge
of the next copy passes the upper transport roller, the shift roller shifts again. This
operation is done every sheet.
When the trailing edge of each page in the next set of copies passes the upper
transport roller, the shift roller shifts in the opposite direction.
