Chapter 6 Practical Examples
■ Documents Do Not Feed Properly
If a document does not feed properly, first confirm the
following:
✔ Are pages sticking together because of static electricity
or another cause?
✔ Are you attempting to scan a document with size, paper
thickness or quality that is not supported by the
scanner? (See “Documents” on p. 3-3.)
✔ Are the feed rollers dirty?
✔ Are the feed rollers worn out?
IMPORTANT
• Double feeding occurs when document pages stick together,
and incompatible paper thickness or quality can cause paper
jams. Check your documents carefully before loading.
• Replacement rollers can be purchased as consumables. If
performance is not improved after cleaning the rollers, contact
your local Canon dealer or service representative to purchase
a Roller Replacement Kit, and replace the rollers (pickup, feed
and retard rollers). (See “Replacing the Transport Rollers” on
p. 5-5.)
If this does not solve the problem, consider the following
possible problems and causes:
Problem Documents do not feed.
Cause The Continuous Manual Feed Mode is
enabled.
Solution Set the Continuous Manual Feed Mode to
[OFF] from the User Mode. (See “Continuous
Manual Feeding Mode Setting” on p. 3-12.)
■ Saved Image Files Do Not Open
If image files saved by CapturePerfect 3.0 cannot be
opened by another application, first confirm the following:
✔ Does the application you are using support
CapturePerfect 3.0 image file types (*.bmp, *.tif, *.jpg
and *.pdf)?
If this does not solve the problem, consider the following
possible causes:
Cause The application does not support multi-
page TIFF files.
Solution Open the files using an application that
supports multi-page TIFF files, or save the
images as single-page TIFF files using
CapturePerfect 3.0.
Cause The compression format used by
CapturePerfect 3.0 is not supported.
Solution Open the image file with CapturePerfect 3.0,
set the compression format to [None], and save
it again.
■ Scanning Results Are Not as Expected
If the scanned images do not appear as expected, one or
more ISIS/TWAIN driver settings may be incorrect, or
your application may not support certain scanner
functions.
Problem The scanned image is too dark (or faint).
Cause The [Brightness] setting is not set to an
appropriate value.
Solution If the image is too dark, set a higher brightness
setting, or if the image is too faint, set a lower
brightness setting.
