13.1 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 registration roller for the printing of the other side.
The ADU mainly consists of the transport rollers and their drive section, the paper guides and the ADU
driving PC board (ADU).
