Swivels the corner stapler and positions it so the staple fires
at an oblique angle at the rear corner of the paper stack.
Drives the positioning roller in the stapling tray.
Drives the jogger fences in the stapling tray to jog both sides
of the stack before stapling.
Raises the bottom fence and stops when the center of the
vertical stack is opposite the edge of the horizontal fold
blade. The distance for raising the blade is prescribed as
one-half the size of the paper selected for the job. For large
paper, (A3, B4) the bottom fence first lowers the stack 10 mm
below the fold position, and then raises it to the fold position.
Drives the large cam that operates the stack junction gate at
the top of the stapling tray. When this gate is open, it directs
the ascending stack to the upper tray if it has been corner
stapled, or if it is closed the gate turns the booklet stapled
stack down so it falls onto the bottom fence of the folding
unit.
Drives the shift roller that operates in shift mode to stagger
document sets as they feed out to the upper tray (making
them easier to separate).
Drives the mechanism that raises and lowers the exit guide
plate.
This is the roving corner stapler, mounted on a steel rail that
staples 1) at the front, 2) at the rear (straight staple), 3) at the
rear (diagonal staple), and 4) font and rear (two staples).
Raises and lowers the upper tray during feed out to keep the
tray at the optimum height until it is full.
Booklet stapler. Staples paper stacks in the center before
they are folded.
Booklet stapler. Staples paper stacks in the center before

Fires the punches that punch the holes in the paper.
Provides two functions: (1) Detects paper entering the
finisher from the copier, and (2) Signals a jam if it detects
paper at the entrance when the copier is switched on.
Detects 1) paper fed from the pre-stack tray to the stapling
tray, and detects 2) paper in the pre-stack when the copier is
switched on. (This sensor performs no timing function. The
entire flow of paper through the pre-stacking mechanism is
controlled by motor pulse counts.)
The photosensor that detects the edge of the paper and
sends this information to the punch unit board where it is
used to position the punch for punching the holes in the
paper.
1) A photosensor that detects and signals that the punch
hopper is filled with punch waste and needs emptying, and 2)
confirms the presence of the punch hopper and signals an
error if it is missing or not installed completely.
Located near the shift roller motor, controls the front-to-back
movement of the shift roller as shifts paper during straight-
through feed.
A flat, photo sensor located inside the guide plate, detects
the leading edge and trailing edge of the paper as it feeds out
to the upper tray during straight-through jobs (with and
