Purge mechanism

This mechanism draws its power from the paper feed motor on the left side of the main chassis.

Gears between paper feed motor and maintenance unit

As described in

Section 3.2.2.1

, the motor drives the PF roller gear L that rotates the paper feed

roller. At the right end of the roller (left in the illustration because the view is from the rear) is the PF
roller gear R, which always meshes with the clutch gear.
