Stitching System - Sharp AR-FN8 Service Manual

IV. STITCHING SYSTEM
1. Outline
The stitching system "stitches" the center of an output stack with staples.
To enable stitching at two locations on a stack, two stitcher units (front, rear) are used. Each
stitcher unit is equipped with a stitcher motor (M7S, M6S) for drive, a stitcher home position
sensor (MS7S, MS5S) for detection of position and a staple sensor (MS6S, MS4S) for detection of
the presence/absence of staples.
The stitcher base is designed so that it may be drawn out to the front from the saddle stitcher for
replacement of the staple cartridge or removal of a staple jam. The stitcher unit in sensor (PI16S) is
used to make sure that the stitcher base is properly fitted to the saddle stitcher.
Safety switches are not mounted for the stitcher unit (front, rear), as the location does not allow
access by the user.
