2-1-1 Paper feed section
The paper feed section consists of the primary feed and secondary feed subsections. Primary feed conveys paper from
the upper drawer, lower drawer or bypass tray to the left and right registration rollers, at which point secondary feed
takes place and the paper travels to the transfer section in sync with the printing timing.
Each drawer consists of a lift driven by the lift motor and other components. Each drawer can hold up to 500 sheets of
paper. Paper is fed from the drawer by the rotation of the forwarding pulley and paper feed pulley. The separation pulley
prevents multiple sheets from being fed at one time, via the torque limiter.
