Adf Scan And Exit - Lexmark CX725 Service Manual

ADF scan and exit

After a predetermined count, the scan document reaches the scan area and the image acquisition process is
initiated. While scanning the document, the sensor (1st scan) is polled to determine if the trailing edge of the
document has reached the sensor.
When the trailing edge of the scan document has reached the sensor (1st scan), then the sensor goes to the
off position. Scanning continues for a predetermined length of time.
When scanning is completed, the trailing edge of the scan document continues to the reverse point. If the scan
job is a simplex job, then the document continues to the exit roller (13) and exits the ADF.
