The next set of copies is then delivered. The motor turns on,
repeating the same process and moving the tray back to the previ-
ous position.
The disk is rotated alternately clockwise and counter-clockwise
through an arc of 180 degrees.
The notches cut into the shift gear disk control the operation of the
shift motor, using shift tray half-turn sensors [F] and [G].
If the job ends with the disk at (1) with only one sensor deactivated,
the motor rotates the disk to the (2) position where both sensors
are deactivated. This is the home position.

11. PUNCH UNIT
A. PUNCH UNIT DRIVE
The punch unit makes 2 or 3 holes at the trailing edge of the paper.
The number of holes depends on a selection made on the opera-
tion panel.
The cam [A] has 2 punches on one side and 3 punches on the
other, and is turned by the punch motor [B]. The punch motor turns
on immediately after the trailing edge of the paper passes the
entrance sensor. The punches on the cam rotate downward and
punch holes in the paper.
After punching a sheet of paper, the cam returns to home position
and stops. Home position depends on whether 2 holes or 3 holes
are being made, so there are two punch HP sensors. Punch HP
sensor 1 [C] is used when 2-hole punching is selected, and punch
HP sensor 2 [D] is used when 3-hole punching is selected. When
the cut-out [E] enters the slot of the punch HP in use (sensor 1 or 2-
hole punching) the motor stops.
The knob (not shown) on the front end of the punch unit can be
turned in either direction to clear paper jammed in the punch unit.

sensor 1 [C] is used when 2-hole punching is selected, and punch
HP sensor 2 [D] is used when 3-hole punching is selected. When
the cut-out [E] enters the slot of the punch HP in use (sensor 1 or 2-
hole punching) the motor stops.
The knob (not shown) on the front end of the punch unit can be
turned in either direction to clear paper jammed in the punch unit.
B. PUNCH WASTE COLLECTION
Punch waste is collected in the punch waste hopper [A] positioned
under the punch unit.
When the level of the punch waste in the hopper rises as far as the
hole [B] in the hopper, the punch hopper full sensor [C] turns on,
stops the job, and triggers a message on the operation to indicate
that the hopper is full and must be removed and emptied.
The job resumes automatically after the hopper is emptied and
returned to the finisher.
The punch hopper full sensor also functions as the hopper set sen-
sor. When the hopper is not in the finisher, or if it is not inserted
completely, the spring loaded sensor arm rotates up and to the right
with the punch waste sensor away from the hole in the hopper
holder and a message is displayed. The message in this case is
the same as the hopper full message.
