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.

○ Configuration without the paper ejection option

1] Paper ejection roller

[2] Paper ejection sensor (PS14)

[3] Reversing flapper

[4] Duplex transport roller 1

[5] Duplex transport sensor (PS17)

[6] Duplex transport roller 2

Configuration with the paper ejection option

1] Reversing roller

[2] Reversing sensor (PS4A)

[3] Duplex entrance sensor (PS3A)

[4] Duplex entrance roller

[5] Duplex transport roller 1

[6] Duplex transport sensor (PS17)

[7] Duplex transport roller 2

The controls and mechanisms of this block are as follows:

No.	Name	Description	Details
a	Reversing	Reverses printing paper.
b	Imaging order control	Controls the order of imaging to improve productivity in duplex continuous printing.	-

a. 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:
