M16
Fold Unit Bottom
Fence Lift Motor
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.
M17
Stack Junction Gate
Motor
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.
M18 Shift Roller Motor
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).
M19 Exit Guide Plate Motor
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).
M21 Upper Tray Lift Motor
Raises and lowers the upper tray during feed out to
keep the tray at the optimum height until it is full.
