Paper feed section

(1) Paper feed section
The paper feeder conveys paper from the paper cassette to the printer. Paper cassette can hold up to 250 sheets of paper.
Paper is fed from the paper feeder by the rotation of the pickup roller and paper feed roller. The retard roller prevents mul-
tiple sheets from being fed at one time, via the torque limiter.
