M28 Lower Transport Motor Drives the rollers that transport paper in the shift and stapling
paper path.
M29 Punch Motor Drives the punch shaft and roller.
M30
Shift Tray Jogger Motor Drives the shift tray jogger fences against the sides of the sheets
to align the stack, then reverses to return them to the home
position

reverses and lowers them to them to the home position.
PCBs
No. Name Description
PCB Main Board (Output Jogger) Controls operation of the shift and output jogger mechanisms.
PCB Main Board Controls the finisher and communicates with the copier.
Sensors
No. Name Description
S01 Entrance Sensor Detects the copy paper entering the finisher and checks for
misfeeds.
S02 Upper Tray Exit Sensor Checks for misfeeds at the upper tray.
S03 Upper Tray Full Sensor Detects when the upper tray is full.
S04 Shift Tray Exit Sensor 1 Controls the output timing of stapled stacks and detects jams.
S05 Shift Tray Exit Sensor 2 Controls the timing of paper in the shift path and detects paper
jams.
S06 Exit Guide HP Sensor Detects whether the guide plate is opened or not.
S07 Paper Height Sensor –
Standby Mode
Detects the height of the tray when the machine is turned on to
position the tray at the standby position.
S08 Paper Height Sensor –
Staple Mode
Detects the height of the paper output on the shift tray and adjusts
the height of the tray in the staple mode.
S09 Paper Height Sensor – Z-
Fold Full
Detects the height of the paper output on the shift tray and signals
when the tray is full when Z-folded paper is output to the shift tray.
S10 Paper Height Sensor –
Shift/Z-Fold
Detects the amount of paper on the shift tray 1) in shift
mode to control operation of the tray lift motor, and 2) when
Z-folded paper is output to the shift tray.
S11 Drag Drive HP Sensor Controls the push and pull movement of the drag roller when it
extends and drags paper back against the back of the shift tray to
keep the edge of the stack aligned on the shift tray.
S12 Shift Tray Half-Turn Sensor
1
Detects whether the shift tray is at either the front or back position.
Controls the side-to-side movement of the shift tray. (This pair of
sensors is used to detect the positions of the leading and trailing
edges of the sheets controls operation of the shift mechanism.)
S13 Shift Tray Half-Turn Sensor
2
Detects whether the shift tray is at either the front or back position.
Controls the side-to-side movement of the shift tray.
S14 Upper Tray Junction Gate
HP Sensor
Detects the upper tray junction gate at its home position.
S15 Stapler Junction Gate HP
Sensor
Detects the staple junction gate at its home position.
S16 Pre-Stack Junction Gate
HP Sensor
Detects the pre-stack junction gate mechanism at its home
position.
S17 Pre-Stack Tray Paper
Sensor (Right)
Detects paper feed in the right side of the pre-stack unit and
detects jams.
S18 Shift Tray Full Sensor Detects when the shift tray is full for paper smaller than B4. The
tray is at its lower limit.
S19 Shift Tray Full Sensor
(Large Paper)
Detects when the shift tray is full for large size paper (B4 or
larger).
S20 Shift Tray Near-Full Sensor Detects when the shift tray is nearly full.
S21 Stapler Tray Exit Sensor Detects jams at the staple tray exit.
S22 Staple Trimmings Hopper Detects when the staple trimmings hopper is full.
