Installing the Automatic Document Feeder
Because the automatic document feeder is heavy, you may want to have
someone help you with this procedure. Also, the document feeder is
large, so be sure to allow adequate space around the scanner.
Follow the steps below to install the automatic document feeder on your scanner:
1. Make sure your scanner is turned
off and unplug the cables.
2. Remove your scanner’s document
cover by grasping the back of
the cover as shown and easing the
cover up.
3. Make sure the document table is
clean and dust free.
4. Position the automatic
document feeder’s mounting
slots over the two mounting
screws located at the back of the
scanner. Slide the automatic
document feeder forward
slightly until the two holes in
front of these slots are aligned
with the screw holes at the back
of the scanner.
Don’t remove the foam
block until you’re done
installing the unit.
