No.
Component
Function
from the nip of the fold rollers, detects the leading and trailing
edge of the booklet to make sure that it feeds out correctly.
S32
Stack Present Sensor
This sensor determines whether a there is paper at the turn junction
gate when the machine is turned on. If a stack is present, this trig-
gers a jam alert. (This sensor performs no dynamic function such
as pulse counting, etc. It only detects whether paper is at the top
of the folding unit when power its turned on.)
S33
Lower Tray Full Sensor -
Rear
This rear sensor is the lower sensor of the lower tray full sensor
pair. Two actuators are attached to the actuator arm that touches
the top of stapled and folded booklets as they feed out. The on/
off combinations of the two sensors are used to detect when the
tray is full and stop the job. (The lower tray is stationary. At tray
full, the job halts until booklets are removed from the lower tray.)
S34
Lower Tray Full Sensor -
Front
This front sensor is the higher sensor of the lower tray full sensor
pair. Two actuators are attached to the actuator arm that touches
the top of stapled and folded booklets as they feed out. The on/
off combinations of the two sensors are used to detect when the
tray is full and stop the job. (The lower tray is stationary. At tray
full, the job halts until booklets are removed from the lower tray.)
Solenoids
SOL1
Proof Junction Gate Sole-
noid
Opens and closes the proof tray junction gate. When the solenoid
switches on, it opens the gate and paper is diverted to the proof
tray. When this gate is closed, the paper goes straight to the upper
tray. I
SOL2
Stapling Tray Junction
Gate Solenoid
Directs paper to the stapling tray. When this solenoid is on, paper
feeds straight through. When this solenoid is off, paper feeds to
the stapler tray below.
SOL3
Positioning Roller Sole-
noid
Engages the stapler transport motor and the positioning roller of
the stapling tray. The positioning roller pushes each sheet down
against the bottom fence to align the bottom the stack for stapling.
(The jogger fences align the sides.)
SOL4
Stapling Edge Pressure
Plate Solenoid
Operates the pressure plate of the stapling unit. The pressure plate
presses down the edge of stack in the stapling tray so it is tight for
stapling.
