No.
Component
Function
sponge roller drags each ejected sheet back against the end fence
of the upper tray to keep the bottom of the stack aligned.
S14
Stapling Tray Paper Sen-
sor
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.
S15
Jogger Fence HP Sensor
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.
S16
Stack Feed-Out Belt HP
Sensor
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.
S17
Corner Stapler HP Sensor
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.
S18
Stapler Rotation HP Sen-
sor
Controls the angle of the position of the corner stapler during ob-
lique stapling.
S19
Upper Tray Full Sensor
(B804/B805)
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.
S20
Upper Tray Full Sensor
(B805 only)
B804: This sensor is not used on the booklet finisher. There is only
one upper tray full sensor (S18).
B805: One of two upper tray full sensors. This is the lower tray full
sensor for A4 and smaller paper. The other upper tray full sensor
(19) is for larger paper.
S21
Punch Unit HP Sensor
Switches off the punch movement motor when the punch unit re-
turns to its home position. Pulse counts determine where the punch
unit pauses for punching and reversing.
