Duplex Transport Block Transports reversed printing paper for duplex printing.

Duplex Transport Block

The duplex transport reverses Single-side printed paper in the paper ejection section and transports it to the resist roller.

The reversing roller differs when the paper ejection option (3-Way Unit-A1) is attached and when it is not.

　

Without 3-Way Unit-A1 Paper ejection roller (Main unit) With 3-Way Unit-A1 Reversing roller (3-Way Unit-A1)

　

The configuration of this block is explained with controls and functions below.

Imaging order control This machine controls the order of imaging on printing paper in continuous duplex printing to improve the productivity of duplex prints. The imaging order differs depending on whether the paper ejection option (3-Way Unit-A1) is attached and where the paper ejection tray is located. By the presence or absence of the paper ejection option (3-Way Unit-A1) and the place of the paper ejection tray, the transport order will be as follows: 　 ○ Duplex printing without the paper ejection option Duplex printing with the paper ejection option (Copy tray 1 or 2) Duplex printing without the paper ejection option (Copy tray 3)
