Theory of Operation 2-7
Trays 2 through 5
When the control logic calls for paper feed, the Nudger Roller moves a sheet of paper
to the Feed Roller. The Feed Roller moves a single sheet of paper out of the tray and
toward the tray’s Take Away Roller. The Retard Roller ensures only one sheet of
paper is fed. The paper then moves past the Pre-Feed Sensor and up the vertical path
driven by a sequence of Take Away Rollers. Feed Out Sensors at each feed point
notify the Engine Logic Board that the paper has arrived at the next Take Away Roller
in the path. The paper continues along the path until the sheet of paper arrives at the
Registration Roller.
