Common Problems and Solutions
This section provides recommended solutions to common problems.
If you have a problem that is not solved by the following, contact your local
authorized Canon dealer.
Q1 The scanner will not turn on.
A1 Confirm that the AC adapter is plugged firmly into a power outlet.
Q2 The scanner is not recognized.
A2 1 Confirm that the scanner is properly connected to the
computer with a USB cable.
2 Confirm that the scanner is turned on. See the previous
" Problem 1" if the scanner does not turn on.
3 The computer's USB interface may not support the scanner.
The scanner cannot be guaranteed to work with all USB
interfaces.
4 Confirm that the supplied USB cable is used to connect the
scanner to the computer. The scanner cannot be guaranteed
to work with all available USB cables.
5 If the scanner is connected to the computer via a USB hub,
try removing the hub and connecting directly to the
computer.
6 On the DR-C225W II, make sure that the Wireless switch on
the back of the scanner is turned off.
Q3 Documents feed askew (scanned images are slanted).
A3 1 Align the document guides to fit the documents as closely as
possible, and load the documents so that they feed straightly.
2 Enable [Automatically straightens skewed] (or [Deskew]) in
the scanner driver settings.
3 If many pages have been scanned since roller cleaning,
clean the rollers. If documents still feed askew, roller
replacement or other maintenance may be needed. See
" Chapter 9 Regular Maintenance" on p.85 for roller
replacement procedures.
Q4 If white lines or streaks appear in scanned images.
A4 Clean both sides of the scanner glass, and the rollers. If a sticky
substance such as glue or correction fluid is found, carefully wipe
with just enough pressure to clean the area where the lines
appear. If the problem cannot be solved by cleaning, the internal
glass may be scratched. Contact your local authorized Canon
dealer.
Q5 Pages are missing.
A5 Then the scanner driver's [Scanning Side] setting is [Skip blank
page], documents with very little black may be unintentionally
skipped. Decrease the [Set the likelihood of skipping blank page]
value (see " When you want to delete the images of the blank
pages in two-sided documents" on p.69 ) , or select another scan
mode setting such as [Simplex] or [Duplex]. If pages are skipped
due to the document double feeding, see " Problem 7 Documents
jam (or double-feed)" .
Q6 Documents jam (or double-feed).
A6 1 If the roller has been installed correctly, clean it if necessary.
2 Proper scanning may not be possible when document pages
stick together due to static electricity. Fan the documents
before you load them.
3 Set the feed selection lever to the non separation position,
and manually feed the scanner one page at a time.
