Theory of Operation
Scanning at Automatic Document Feeder
The media set in the document tray is conveyed through the Feed Roller,
Takeaway Roller, and Registration Roller. The media image is scanned at the
Constant Velocity Transport (CVT) position, and the media is ejected through
the Exit Roller.
Media Setting
When media is set in the paper tray and pushed into the tray until its lead
edge stops, an Actuator moves to place the ADF Document Sensor in the
unshielded (unblocked) state, indicating media detection.
Preparation for Feed
The media in the paper tray starts feeding when the Start button is pressed.
The Nudger Roller moves down and presses onto the media in the paper tray
to enable media feed. The Nudger Roller moves down with normal rotation of
the ADF Motor. Upon completion of media feed, the ADF Motor reverses
rotation to return the Nudger Roller to its normal position.
