●
If the copy job is complete, the ADF paper present sensor is deactivated. The feed motor reverses
rotation to raise the pick roller.

If the copy job is not complete, the ADF paper present sensor is active. The product firmware
detects additional pages in the input tray and the process repeats.
Front-side and back-side background selector
NOTE: The product automatically controls the operation of the front-side and back-side background
selectors.
The background selectors change the reflective surface behind a duplex or simplex scanned page from white
to black. Doing so allows the firmware to recognize the edges of a scanned page by passing it over a black
background.
The product uses the background selectors for specific scan jobs. Scan jobs like optical character recognition
(OCR) and scan to folder require a black reflective background so that the firmware can correctly scan the
page from edge-to-edge.
The front-side background selector is a non removable component of the automatic document feeder. The
back-side background selector assembly is located under the automatic document feeder input tray and is
removable to allow access for cleaning the back-side scan module glass.
