Sensors
No. Name Description
S1 Booklet Output Tray
Full Sensor – Front
This front sensor is the higher sensor of the booklet 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 booklet tray is stationary. At tray full, the
job halts until booklets are removed from the booklet tray.)
S2 Booklet Output Tray
Full Sensor – Rear
This rear sensor is the lower sensor of the booklet 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 booklet tray is stationary. At tray full, the
job halts until booklets are removed from the booklet tray.)
S3 Clamp Roller HP
Sensor
Controls the movement of the clamp retraction roller (the idle roller
of the clamp roller pair).
S4 Finisher Entrance
Sensor
Provides two functions: (1) Detects paper entering the finisher from
the copier, and (2) Signals a jam if it detects paper at the entrance
when the copier is switched on.
S5 Fold Bottom Fence
HP Sensor
Controls the movement of the bottom fence in the folding unit using
pulse counts based on the size of the paper selected for the job to
position the stack correctly for feeding.
S6 Fold Plate Cam HP
Sensor
Along with the fold plate HP sensor (S29), this sensor controls the
movement of the fold plate. The actuator mounted on the end of the
roller that drives the folder plate forward and back makes three full
rotations, i.e. the actuator passes the sensor gap twice and stops on
the 3rd rotation and reverses. This accounts for the left and right
movement of fold plate.
S7 Fold Plate HP Sensor Along with the fold plate cam HP sensor (S30) this sensor controls
the movement of the fold plate. The fold plate has arrived at the
home position when the edge of the plate enters the gap of this
sensor.
S8 Fold Unit Entrance
Sensor
Detects 1) the leading edge of the stack during booklet stapling, and
2) also used to signal an alarm if a paper is detected at the entrance
of the fold unit when the copier is turned on.
S9 Fold Unit Exit Sensor 1) Detects the folded edge of the stack as it feeds out from the nip of
the fold rollers, stops the rollers, and reverses them 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.
S10 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.
S11 Stack Tray Exit
Sensor
Detects 1) paper fed from the stack tray to the stapling tray, and
detects 2) paper in the stack when the copier is switched on. (This
sensor performs no timing function. The entire flow of paper through
the stacking mechanism is controlled by motor pulse counts.)
S12 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.
S13 Stack Junction Gate
HP Sensor
Controls the opening and closing of the stack junction gate.
Switches on when the stack junction gate is open and at the home
position.
S14 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.)
