■ 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.)

Chapter 6 Practical Examples
CapturePerfect 3.0 image file types (*.bmp, *.tif, *.jpg
and *.pdf)?
The application does not support multi-
page TIFF files.
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.
The compression format used by
CapturePerfect 3.0 is not supported.
Open the image file with CapturePerfect 3.0,
set the compression format to [None], and save
it again.
The [Brightness] setting is not set to an
appropriate value.
If the image is too dark, set a higher brightness
setting, or if the image is too faint, set a lower
brightness setting.
