Chapter 6 Principles of Operation
13. Actions of Main Functional Components
The Option OCT is available as an optional unit for JIGEN laser printer. Offset output
is enabled by mounting this optional unit to the top of the 500 Paper Exit.
MOTOR ASSY OCT
This motor gives the driving force to the ROLL OCT LOWER and ROLL OCT
UPPER, which transport the printed paper to the tray of the OCT.
MOTOR ASSY OFFSET
This motor gives the driving force to the CHUTE OFFSET ASSY via the GEAR
CAM.
SOLENOID ASSY GATE
This solenoid switches between the paper paths to the standard and OCT paper
output trays. When the SOLENOID ASSY GATE operates, the GATE OCT EXIT is
operated by the LINK GATE OCT pushed downward against the spindle of the
SOLENOID ASSY GATE. Thus, the paper output direction is switched to the OCT
paper output tray.
PWBA OCT
A CPU is installed in the PWBA OCT. This CPU receives instructions from HVPS/
MCU and information from sensors and switches, and controls the operation for
transporting the paper through the OCT.
S/W REAR COVER
This switch detects that the COVER REAR is closed.
SENSOR OCT
This sensor detects the presence or absence of paper in the OCT.
Sensor Full Stack OCT This sensor is located on the PWBA OCT, and detects that
the paper output tray is full, using the ACTUATOR FULL STACK.
Sensor Offset
This sensor is located on the PWBA OCT, and detects an offset operation, using
the Actuator in the CHUTE OFFSET.
ROLL OCT LOWER
This roll transports the printed paper sent out from the Fuser, to the ROLL UPPER
OCT.
ROLL OCT UPPER
This roll discharges the printed paper sent out from the ROLL OCT LOWER, to the
tray of the OCT.
CHUTE OFFSET ASSY
This is driven by the MOTOR ASSY OCT and GEAR CAM. During paper output, it
moves right and left to perform offset operation. The standard distance between
offset paper and non-offset paper is 25mm. The Offset Deal (the closest distance
between a batch of offset sheets and a batch of non-offset sheets) should be more
than 10mm.
