10. Actions of Main Functional Components
The Option Duplex is available as an optional unit for JIGEN laser printer. Duplex
printing is enabled by mounting this optional unit to the rear side of the base engine.
SWITCH DUPLEX
This switch detects that the HSG LOWER DUP and COVER HSG DUP are closed.
SENSOR DUP
This sensor detects the presence or absence of paper in the Duplex.
FAN DUPLEX
This fan vents air within the Duplex and takes in outside air, to prevent abnormal
temperature rise in the Duplex
ROLL DUP
This roll feeds the paper having the printed first surface back into the printer through
the Duplex, to print on the second surface.
PWBA DUPLEX
A CPU is installed in the PWBA DUPLEX. This CPU receives instructions from
HVPS/MCU and from sensors and switches, and controls feeding operation in the
PWBA DUPLEX. A flash ROM is used with the CPU installed in the PWBA
DUPLEX, so that the firmware can be rewritten through communications.
MOTOR DUPLEX
This motor gives the driving force the three ROLL DUPs, which transport the paper
into the printer.
