Detects the HP of the front fence at the front of
the finisher.
Located at the bottom left corner of the finisher.
When the actuator on the tray rail switches this
sensor ON, this signals tray full.
Used to monitor the positions of the edge
depressors that press down on the trailing edge
of the stack at the end fence. When the top of
the stack pushes the depressors up, this
switches the sensor OFF and signals the tray lift
motor to lower the tray.
Detects the HP of the positioning roller when it is
up.
Detects the HP of the rear fence at the back of
the finisher.
Detects HP of the stapler at the front of the
finisher.
Detects paper on the stapling tray,
When a stack is output, the tray lift motor lowers
the tray slightly. At this time, the stack depressor
solenoid switches ON and retracts the edge
depressors briefly so that the trailing edge of the
stack can fall onto the tray. The solenoid then
switches OFF and lowers the arms against the
trailing edge of the stack to keep it down against
the end fence.
