MAIN FUNCTIONS
SWITCH-DUP DOOR
The SWITCH-DUP DOOR detects whether the Duplex door is opened or closed.
SOLENOID ASSY DUP
The SELENOID ASSY DUP switches the gate inside the Fuser. When the
SELENOID ASSY DUP turns ON, the actuator pushes the gate up, and the paper
is fed to the Invert section.
MOTOR ASSY DUP INV
The MOTOR ASSY DUP INV drives the ROLLER ASSY INVERTER, and feeds
paper to the Transport section. When the paper ejected from the Fuser comes to the
catch tray side, the Motor starts to rotate in reverse, and the paper is fed to the
Transport section.
SENSOR UPPER PASS
The SENSOR UPPER PASS detects that paper has been fed to the reversing
section of the Duplex. (No paper state : Shielding the sensor)
MOTOR ASSY DUP
MOTOR ASSY DUP drives ROLLER ASSY DUP and ROLLER ASSY DUP
OUT to feed paper inside the Transport section.
SENSOR LOW PASS
The SENSOR LOW PASS detects that paper has been fed inside the Transport
section. (No paper state : Shielding the sensor)
