No. Component Function
so the fold feeds back into the nip, 2) when the folded booklet
finally emerges 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 triggers 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
Solenoid
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
Solenoid
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.
SOL5
Booklet Pressure Roller
Solenoid
When the paper stack in the stapling tray feeds to the folding
unit, this solenoid turns on and operates the roller that
pushes on the surface of the stack to flatten it.
Switches
SW1 Front Door Safety
Switch
The safety switch that cuts the dc power when the front door
is opened.
SW2 Upper Tray Limit SW A micro-switch that cuts the power to the upper tray lift motor
when the upper tray reaches its upper limit. This switch
duplicates the function of the upper tray limit sensor (S12)
and stops the upper tray if S12 fails.
