Adf Paper Path - Lexmark MB2236 Service Manual

ADF paper path

After the sensor (ADF paper present) detects paper in the ADF tray, the pick roller moves the paper into the
ADF.
The paper passes through the feed roller and separator pad. The separator pad minimizes the possibility of
feeding multiple sheets.
The paper passes through the transport rollers, and then actuates the sensor (ADF scan). The scan roller moves
the paper to the scan area, and then the document is scanned.
The scan rollers continue to move the paper to the scan area until the trailing edge of the paper reaches the
sensor (ADF scan). When the trailing edge of the paper reaches the sensor (ADF scan), the sensor goes to the
off position. Scanning continues for a predetermined length of time.
The exit rollers move the paper into the ADF bin.
