My scanner is con-
nected but it will not
feed my document or
do anything else. Your document is not set correctly. Insert your document until you feel the top edge of
the document touch the inside of your scanner.
Your document is too thin or too thick. Check that your document is acceptable (see Doc-
ument Specifications on page 12).
If your document is not the problem:
1. Confirm that the Micro USB Cable connecting
your scanner to your computer is properly con-
nected.
2. Reinstall the scanner driver from the DVD-ROM.
The scanner’s top cover is open. Close the top cover and start scanning again.
The scanner is turned off because the
auto power off function is active. Press the Power button to turn on the scanner.

My scanner gets
warm. It is normal for your scanner to emit a
small amount of heat after prolonged
use. If there is a strange smell coming from the scanner
or the scanner feels a little bit hot to the touch, im-
mediately remove the Micro USB Cable from your
scanner and computer.
The scan quality is
poor. Paper dust has accumulated inside
your scanner. Clean your scanner (see Scanner Maintenance on
