4 ] Purge Mechanism - Brother MFC620CN Service Manual

[ 4 ] 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.
