15. AUTOMATIC DUPLEXING UNIT (ADU) (OPTION: MD-0102)

15.1 General Description

The Automatic Duplexing Unit (ADU) is a unit to reverse a sheet of paper at duplex copying.
A switchback method using the exit roller is adopted for the ADU of this equipment. Immediately after
the printing of one side (fusing process) is completed, the paper is switchbacked by the exit roller. The
paper being reversed is then transported to the 1st transport roller for the printing of the other side.
In this ADU, the transport of the switchbacked paper again accelerates and this speed is maintained to
enhance the productivity of duplex printing.
The ADU mainly consists of the transport rollers and their drive system, paper guide and ADU entrance/
exit sensor.
