Canon DR-C225W 9707B003 マニュアル

###HOME > Chapter 12 Troubleshooting > Common Problems and 
Solutions###

If you have a problem that is not solved by the following, contact your local 
authorized Canon dealer.

A1

Confirm that the AC adapter is plugged firmly into a power outlet.

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, make sure that the Wireless switch on 
the back of the scanner is turned off.

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.87 for roller 
replacement procedures.

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.

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.71), 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)".

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.
