time to lift the pickup roller.)
MX-M316N OPERATIONAL DESCRIPTIONS 11 – 4
c. Duplex scanning
Images on the document surface are scanned, and detection of the
rear edge of the document by sensor SPPD3 triggers the following.
That is, when the rear edge of the document passes the reverse gate,
the transport motor is reversed.
Due to the above operation, the paper exit roller is reversed to switch-
back the document, returning it to the registration roller section and
aligning (registration) the document.
Then the transport motor is rotated normally to transport the document
to the scanning section, scanning images on the back surface.
To reset the page order of the documents, the following operations are
made which are triggered by the detection of the rear edge of the doc-
ument. That is, when the rear edge of the document passes the
reverse gate, the transport motor is reversed.
Due to the above operation, the paper exit roller is reversed to switch-
back the document, returning it to the registration roller section and
aligning (registration) the document.
Then the transport motor is rotated normally to transport the document
to the paper exit section and discharge it.
When a duplex document is scanned, the document lead edge section
and the rear edge section intersect. At that timing, the paper exit roller
pressure release solenoid is turned OFF to make a gap between the
paper exit roller (drive) and the paper exit roller (idle).
During the time from when the document rear edge passes the scan-
ning section to when it is switch backed and send to the registration
roller section, the paper exit roller pressure release solenoid is turned
ON to keep the paper exit roller (drive) and the paper exit roller (idle) in
contact.
