∗1. Paper route change

The route of a paper from the fuser section is changed by

the paper exit change cover gate: one path is to cause the

paper to come out of the exit, and the other is to cause the

paper to go to the ADU reversal section.

In case of one-sided copying mode, paper goes to the exit,

and in case of two-sided copying mode, it goes to the ADU

reversal section.

Theexit paperchangeover gateis controlledby turningon/

off the ADU gate solenoid (SD13).
