Theory of Operation
ADF Media Path
The media set in the document tray is conveyed through the Feed Roller and
Takeaway 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 an original is set in the Document Tray and pushed into the tray until its
lead edge stops against the Document Stopper, 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.
