Duplex Unit Transport Motor Control
Rotation of the Duplex Unit Transport Motor is controlled by the signals output from the
Duplex Control Board.
Duplex Unit Loop Correction Control
■ A loop correction mechanism is provided to prevent skew from occurring in the second
page.
■ The Duplex Registration Solenoid (SL6 DU) is energized after the lapse of a given period
of time after the Duplex Paper Loop Sensor (PC10 DU) has been activated. This drives the
Duplex Registration Roller. When the Duplex Registration Roller is driven, the paper is
conveyed into the machine.
2-Sided Printing Method
The following two types of 2-sided printing methods are available.
Note: Automatic 2-sided printing is not effective when the FD length is less than
276 mm.
2-sided printing
method
2-sided printing with a single sheet of paper resident in the
system
2-sided printing with two sheets of paper resident in the
system (When the FD length is no less than 276 mm, no more
than 297 mm).
