Clamp Roller
Retraction Motor
Retraction Motor
Drives a large cam that alternately
clamps and unclamps the clamp
retraction roller, the idle roller of the
clamp roller pair. When these rollers
are clamped, they are part of the
paper feed path and feed the stack
toward the bottom fence of the fold
unit. When the idle roller is retracted,
the stacks falls a very short distance
(3 mm) onto the fold unit bottom
fence below. These rollers remain
unclamped while the bottom fence
positions the stack for folding and
while the stack is folded by the fold
rollers.

Fence Lift Motor
Fence Lift Motor
Raises the bottom fence and stops
when the center of the vertical stack
is opposite the edge of the horizontal
fold blade. The distance for raising
the blade is prescribed as one-half
the size of the paper selected for the
job. For large paper, (A3, B4) the
bottom fence first lowers the stack
10 mm below the fold position, and
then raises it to the fold position.

Full Sensor - Front
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.)

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.

FLDCMHP
Fold Plate Cam HP
Sensor
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.
