MX-FN19 OPERATIONAL DESCRIPTION 6 – 19
Second and Subsequent Sheets
The finisher controller PCB drives the swing motor (FSWM) when
the trailing edge of the second sheet has moved past the No.1 feed
roller to lower the swing guide. Then, it reverses the delivery motor
to turn the delivery roller (upper) and the return roller and deliver
paper to the stapling tray. At this time, the delivery roller (lower) is
not turned because the delivery lower roller clutch (FAORC) is off.
Presence of paper in the stapling tray is detected by the stapling
tray paper sensor (FSTPD).
When paper is fed to the stapling tray, the swing motor (FSWM)
runs to raise and lower the swing guide. If the swing guide home
position sensor (FSWHPD) detects the raise of the swing guide,
the swing motor is stopped, and the swing guide is held at the
raised position.
After the stapling tray paper sensor detects the presence of paper,
the alignment motors (FFJM/FRJM) are run to align paper.

Stapling Last Sheet
When the last sheet has been put in order, the finisher controller
PCB turns on the alignment motors (FFJM/FRJM) to move the
alignment plates to the alignment positions (to butt the plates
against the stack). Then, the finisher controller PCB staples at the
predetermined position.
After stapling, the finisher controller PCB runs the swing motor
(FSWM) to lower the swing guide. Then, paper stack is delivered to
the tray by the delivery roller, return the roller, and the trailing edge
assist guide.

E. Stitcher unit
The stitcher base unit consists of two stitchers and stitcher bases.
The stitchers are fixed in position, and are not designed to slide or
swing.
Stitching is executed by driving the rotary cam by the stitcher
motors (FSFSTM, FSRSTM). The front and rear stitcher units are
operated with a time delay so as to prevent wrinkling of paper
between staples and to limit the load applied to the power supply.
(A time delay for initiating the stitcher motor startup current helps
decrease the load on the power supply.)
The stitcher home position sensors (FSSHP2, FSSHP1) are used
to monitor the movement of the rotary cam, enabling identification
of individual stitcher operations. The presence/absence of staples
inside the staple cartridge fitted to the stitcher is detected by the
staple sensors (FSSD2, FSSD1).
The alignment plates keep both edges of the stack in place while
stitching takes place.
