Troubleshooting
This section describes the problems that may occur while using the 
scanner and how to resolve them.
It you cannot resolve a problem, contact your local authorized Canon 
dealer or your service representative.
Common Problems and Solutions
Problem 1 The scanner will not turn on.
Solutions (1) Confirm that the power switch is set correctly. (2) Confirm that the AC adapter is plugged firmly into a 
power outlet.
Problem 2 The scanner is not recognized.
Solutions (1) Confirm that the sc anner is properly connected to 
the computer with a USB cable.
(2) Confirm that the scanner is turned on. See  “Problem 
1 The scanner will not turn on.” .
(3) The computers 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) Disconnect the USB cable, and connect it again. Problem 3 Documents feed askew (scanned images are 
slanted).
Solutions (1) Align the document guides to fit the documents as  closely as possible, and load the documents so that 
they feed straightly.
(2) Enable the [Deskew] scanner driver setting.
(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. Refer to the  page 61 for roller 
cleaning and replacement procedures.
Problem 4 Both sides are not scanned even when the Duplex  scanner driver setting is enabled.
Solutions In CaptureOnTouch or C apturePerfect 3.0, executing a 
job for which single-sided (simplex) scanning is 
registered will always result in simplex scanning, 
regardless of scanner driver settings. For example, if 
[Simplex] is selected under the [Scanner setting] tab of 
the [Job Register] dialog box in CaptureOnTouch, 
scanning will always be single-sided for that job. Even if 
you configure scanner driver settings from [Scan Batch 
to File] under the [Scan] menu in CapturePerfect 3.0, a 
job will always be performed according to its registered 
settings. To perform duplex scanning, either change the 
job setting or create another job for duplex scanning.
Problem 5 If white lines or streaks appear in scanned images.
Solutions Clean both sides of the scanner glass, and the rollers  (both rubber and metal). 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.

Problem 6 Pages are missing.
Solutions When the scanner drivers [Scanning Side] setting is [Skip Blank Page], documents with very little black may 
be unintentionally skipped. Select another scan mode 
setting such as [Simplex] or [Duplex], or decrease the 
[Ratio of black pixels]. If pages are skipped due to the 
document double feeding, see  “Problem 7  Documents 
jam (or double-feed).” .
Problem 7 Documents jam (or double-feed).
Solutions (1) Clean the feed rollers if necessary. (2) Proper scanning may not be possible when document pages stick together due to static 
electricity. Fan the docum ents before you load them.
Problem 8 Each scanned image of a multi-page document is  saved as a separate document.
Solutions With CaptureOnTouch, you can scan multiple pages  into one image file when TIFF or PDF file format is 
selected. To do this, select [File type], click the [Detail 
Settings] button, and select [Save all pages as one file] 
in the displayed dialog box.
When you select [Scan Batch to File] from the [Scan] 
menu in CapturePerfect, a dialog box appears with a 
pull-down menu at the bottom that allows you to select 
[Single Page], [Multi Page (All Pages)], or [Multi Page 
(Specified Pages)]. If you select [Single Page], each 
page of a multi-page document is saved as a separate 
image file. To save multiple pages to a single image file, 
select [Multi Page (All Pages)] or [Multi Page (Specified 
Pages)].
Problem 9 Documents feed, but no scanned images are saved.
Solutions When Panel-Feeding is selected as the feeding method  on the scanner drivers sett ing screen, after a document 
is fed, scanning does not occur until the scan button is 
clicked on the scan panel. 
Problem 10 Scanned images of multiple pages cannot be saved  in a single JPEG or BMP file.
Solutions Multiple scanned images cannot be saved in a single  JPEG or BMP file. Save the images in either TIFF or 
PDF format. Problem 11 An error message is displayed.
Solutions Confirm the nature of the error, and resolve the problem. 
Press the STOP button to clear the error message. The 
solution for each error is as follows.
Problem 12 Cannot perform ADF scanning.
Solutions Scanning cannot be performed from the feeder when  the business card feeder is open. Close the business 
card feeder if it is open.
Problem 13 Auto start does not function.
Solutions The document detection  sensor on the feeder does not 
function when the business card feeder is open. 
Therefore, even if documents are placed in the feeder, 
scanning will not begin automatically if the business 
card feeder is open. Close the business card feeder.
Problem 14 The “Warming up” message appears.
Solutions If this procedure is per formed immediately after turning 
the scanner ON or while the power indicator is not lit, the 
following appears on the computer display. In this case, 
scanning begins after the scanner finishes warming up. 
Warm up may take up to 30 seconds.
Error Message Solution
Paper jammed in scanner; clear 
paper and push STOP button. A paper jam has occurred. Remove 
the jammed paper. 
(See p. 68.)
The scanner cover or upper unit is 
open. Remove jammed paper, and 
push STOP button. Close the scanner cover or upper 
unit.
Release the lock switch. After 
releasing the lock switch, press the 
STOP button. The lock switch is locked. Unlock the 
lock switch. 
Feeder is not Connected. The ADF connector on the rear panel  of the scanner is disconnected. Insert 
the ADF connector all the way. 
A double paper-feed has occurred. 
Please check the document and the 
scanned image on the display and 
scan the document again. Scanning has stopped due to 
document double-feed. Check the 
scanned images to confirm how much 
of the document was scanned, and 
continue scanning accordingly.

Software Troubleshooting
This section describes troubleshooting problems and solutions for 
operating the supplied software (CaptureOnTouch and 
CapturePerfect).
If scanning is too slow
(1) Close other running programs, if any.
(2) Scanning can be slowed down by memory shortage caused by 
memory-resident applications such as anti-virus programs. Close 
such memory-resident programs if necessary to free up memory 
space.
(3) When insufficient hard disk space  is available, the scanner may be 
unable to create the necessary temporary files for scanned data. 
Delete unneeded data on the hard disk to free up more space.
(4) Scanning is slow if the computers USB port is not Hi-Speed USB  2.0 compliant. 
(5) If using a common USB cable that is not Hi-Speed USB 2.0 
compliant, replace the cable with  the supplied compliant cable.
(6) When the scanner is connected to the computer via a USB hub  that is not Hi-Speed USB 2.0 compliant, remove the hub and 
connect the scanner directly to the computer.
If scanned image files cannot be opened 
in an application
(1) Scanned images saved as multi-page TIFF files can be opened only by programs that support this file format.
(2) Images saved as compressed TIFF files (single- as well as multi- page) can only be opened by programs that support the 
compressed format. This can occur with programs that are not 
compatible with CaptureOnTouch or  CapturePerfect. In this case, 
select “None” as the image file compression format before 
scanning. 
If CapturePerfect cannot open some PDF 
files
Some PDF files created by non-Canon programs cannot be opened 
by CapturePerfect.
