C. Fixing and Delivery Unit
The upper and lower rollers of the fixing unit, and the face-up and face-down delivery rollers are
driven by the main motor (MT1).
The paper separated from the photosensitive drum is fed into the fixing unit, and sent from
the fixing unit by the fixing roller and fixing unit delivery roller.
The paper sent from the fixing unit is detected by the fixing unit delivery sensor (PS1403).
