Name
Detects if the hopper that holds stapling trimmings is set correctly
or incorrectly.
Detects the pre-stack stopper mechanism at its home position.
Detects paper feed in the right side of the pre-stack unit. Controls
the release timing of the pre-stack stopper, and starts the pre-
stack transport motor. Also detects paper jams.
Detects a paper jam if there is paper at the entrance of the stapler
unit junction gate when the machine is turned on or after the door
is closed.
Detects the home position of the stack feed-out belt.
Detects paper in the stapler tray.
Detects the home position of the jogger fence in the stapler tray.
Detects the bottom fence at its home position.
Detects the top fence at its home position.
Detects the home position of the positioning roller.
Detects the home position of the center stack plate.
Detects the home position of the front stack plate.
Detects the home position of the rear stack plate.
Detects the home position of the staple unit for side-to-side
movement.
Paired with Stapler Rotation Sensor 2. .This sensor pair controls
the positioning of the corner stapler for the horizontal, 45
and 75
Paired with Stapler Rotation Sensor 1 .This sensor pair controls
the positioning of the corner stapler for the horizontal and 45
angle stapling positions.
Detects when the punch-out hopper is full and detects when the
punch tray is set.
Detects the cam home position for the 2-hole punch. 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 is used when 2-hole punching is selected, and punch HP
sensor 2 is used when 3-hole punching is selected. When the cut-
out enters the slot of the punch HP in use (sensor 1 or 2-hole
punching) the motor stops.
Detects the cam home position for 3-hole punch. 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 is used
when 2-hole punching is selected, and punch HP sensor 2 is used
when 3-hole punching is selected. When the cut-out enters the
slot of the punch HP in use (sensor 1 or 2-hole punching) the
motor stops.
Detects the actuator on the rear shift tray jogger fence and
switches off the shift tray jogger motor, and signals the machine to
turn on the shift tray jogger retraction motor to raise the fences at
the end of a job.
Detects the jogger fences of the shift tray jogger unit at their home
positions.
