Canon STAPLER STACKER SS-72, Service Manual

Page: 44 / 130

2. First page
The stapler stacker driver stops the delivery motor (M2) when the trailing edge of the first page
passes the delivery roller 1 by 20mm. 0.2 seconds later, M2 is rotated counterclockwise, which
shifts the M2 gear to the swing guide gear side. As a result, M2 rotates the swing guide gear
and the swing guide is lifted (open). The swing guide stops when it is detected by the swing guide
close sensor (PI18).
When the swing guide is open, the paper is pulled back by the rubber rollers of the delivery
roller 1 to the staple tray and is detected by the staple tray paper sensor (PI4).
The stapler stacker driver lifts the tray by 20 mm and drives the adjustment plate motor (M3)
after P14 detected the paper, and aligns the paper.
