9.4.1 Overview
0019-8980
The paper fed from the fixing assembly to the reverse unit is sent to the reverse assembly.
When delivery is performed, the paper is transported to the delivery tray. When duplexing printing is performed, the paper is sent to the duplexing feed assembly
where transfer and fixing are performed for the second side.
The duplexing feed assembly corrects paper skew and the position to start writing an image in the main scanning direction for the second side.

The reverse driver PCB controls the operational sequence of the reverse assembly and duplexing feed assembly using an 8-bit CPU (IC801).
The reverse driver PCB performs serial communication with the DC controller. It drives each load according to the signal sent from the DC controller.
