The stapler motor [A] drives the staple sheet drive belt [B].
The staple sheets are fed under the hammer [C].
The stapler motor drives the staple hammer via gears [D], two eccentric cams
[E], and two links [F].
When the aligned copies are brought to the staple position by the grippers,
the stapler motor starts rotating. When the cams complete one rotation, the
staple home position sensor [G] is deactuated. The stapler motor then stops.
When the paper sensor in the grip assembly does not detect that the copies
are under the hammer, the stapler motor does not rotate.
A paper sheet [H] with a notch cut-in is positioned at the bottom of the staple
cartridge. This paper sheet is fed out after the last staple sheet. When the
leading edge of the notch in the sheet is detected by the staple end sensor
[I], the sorter stapler unit recognizes the staple near end condition. After the
job is completed, the Add Staple indicator lights on the copier operation panel
and the Start key turns to red whenever the staple mode is selected.
