2.5.11 OCT

This printer has the OCT as an option. Installing it at the top of the 500 Paper Exit
enables offset exit.
MOTOR ASSY OCT
This motor gives driving force to the ROLL OCT LOWER and ROLL OCT UPPER
that transport printed paper to the tray of the OCT.
MOTOR ASSY OFFSET
This motor gives driving force to the CHUTE OFFSET ASSY via the GEAR CAM.
SOLENOID ASSY GATE
This solenoid is provided to switch between the paper paths to the normal paper exit
tray and to the paper exit tray of the OCT. When the SOLENOID ASSY GATE is
activated, the GATE OCT EXIT is operated by the LINK GATE OCT pushed down by
the spindle of the SOLENOID ASSY GATE to switch the paper exit direction of paper
to the OCT paper exit tray.
PWBA OCT
The PWBA OCT, incorporating a CPU, the PWBA OCT receives instructions from the
HVPS/MCU and information from the sensors and switches to control paper transport
operation in the OCT.
S/W REAR COVER
This switch detects that the COVER REAR is closed.
SENSOR OCT
This sensor detects presence/absence of paper in the OCT.
SENSOR FULL STACK OCT
Located above the PWBA OCT, this sensor detects that the paper exit tray is full by
means of the ACTUATOR FULL STACK.
Operating Principles

ROLL OCT LOWER
This roll transports the printed paper, which is fed from the Fuser, to the ROLL
UPPER OCT.
ROLL OCT UPPER
This roll ejects the printed paper, which is transported from the ROLL OCT LOWER,
to the tray of the OCT.
