Sensor (B804/B805)
B804/B805
back against the end fence of the upper tray to keep the
bottom of the stack aligned.
A photo sensor that detects whether paper is in the
stapling tray. When this sensor detects paper, the
bottom fence motor raises or lowers the bottom fence to
position the selected paper size for booklet stapling.
Detects the home position of the jogger fences. When
the actuator on the jogger fence interrupts this sensor,
the jogger fence is in its home position and the jogger
fence motor (M15) stops.
Controls the position of the stack feed-out pawl on the
stack feed-out belt. Once the actuator on the feed belt
nudges the feeler of this sensor near the top of the
stapling unit, the feed out belt motor (M5) remains on for
the time prescribed to position the pawl at the home
position to catch the next stack.
Located at the front the stapling tray and mounted
above the steel rod where the corner stapler travels, this
sensor detects the home position of the corner stapler.
The corner stapler is in its home position when the
actuator on the corner stapler unit interrupts this sensor.
Controls the angle of the position of the corner stapler
during oblique stapling.
B804: When the actuator on the side of the upper fence
enters the gap of this sensor, the sensor signals that the
upper tray is at its lowest position (full) and stops the
job.
B805: One of two upper tray full sensors. This is the
higher tray full sensor for A3 and other heavy paper.
The other upper tray full sensor (20) is for lighter paper.
