MECHANISM DESCRIPTION

2.1

General Mechanicsm

When the Duplex Unit receives an instruction for both-sided printing from the unit, the separator
will be opened by the action of a solenoid within Duplex and the route will be shifted to the one
into the Duplex after one-sided printing of papers, which are fed from the tray, are completed.
At this time, as the roller (1) rotates in the direction of arrow A, a sheet is retracted in the rear of
the cassette. And then, a given time later after the edge of the sheet passes through the IN SNS
(DUP), the roller will reverse and the roller (1) rotates in the direction of arrow B and sending out
the paper into the Duplex. After that, it passes though the roller (2) and (3), and is fed again into
the unit, given another-sided printing and ejected.
