Problem 5
Documents fed askew are causing scanned images
to be slanted.
Solutions
(1) Align the document guides to fit the documents as
closely as possible, and place the documents so
that they feed in straight.
(2) Enable [Deskew] in the settings of the scanner
driver.
(3) If many pages have been scanned since the last
roller cleaning, clean the rollers and separation pad.
If documents still feed askew, roller replacement or
other maintenance may be needed.
(4) Perfectly straight scanning may not be possible for
the document due to the structural design of the
scanner.
Problem 6
Two-sided scanning is set in the scanner driver but
both sides are not scanned.
Solutions
Note that if you use a job for which scanning only one
side is set in CaptureOnTouch, only one side will always
be scanned regardless of the settings of the scanner
driver. For example, if you set one-sided scanning on
the [Scanner setting] tab of the [Job Registration] dialog
box of CaptureOnTouch, one side will always only be
scanned with that job. Change the setting of the job or
create a job for scanning both sides.
Problem 7
White lines/streaks appear in the scanned image.
Solutions
Clean the scanning glass (both the top and bottom) and
rollers. When cleaning off dirt with adhesive properties
such as glue and correction fluid, try applying a little
pressure when wiping the places corresponding to
where the lines appear. If the problem is not solved after
cleaning, the inside of the glass may be scratched.
Contact your local authorized Canon dealer or service
representative.
Problem 8
Pages are skipped (missing).
Solutions
If [Scanning Side] of the scanner driver is set to [Skip
Blank Page], pages with few black portions may be
unintentionally deleted (skipped). Select another
scanning mode such as simplex or duplex, or reduce the
ratio for black dots. For the solution for missing pages
caused by double feeding, see the following “
Pages become jammed or double fed.
”
Problem 9
Pages become jammed or double fed.
Solutions
(1) Scanning cannot be performed properly if the pages
of the document are sticking together because of,
for example, static electricity. Before you load a
document, thoroughly fan the pages.
(2) Reduce the number of pages that you load into the
scanner at one time.
Problem 10 I want to save scanned images in JPEG format, but
they are saved in TIFF format.
Solutions
If a document is scanned when [Mode] is set to [Auto
Color Detection] in the settings of the scanner driver,
documents detected as black and white are
automatically saved in the TIFF format regardless of the
setting. This is because the JPEG format does not
support black and white binary images. If you want to
save all scanned images in JPEG format, set [Mode] to
[Color] or [256-level Gray] and then perform scanning.
Problem 11 The scanned images are saved separately as
multiple documents.
Solutions
When output file format is set to TIFF or PDF in
CaptureOnTouch, multiple pages can be saved as one
scanned image. To achieve this, select [File type], and
then click the [Advanced Settings] button and select
[Save all pages as one file] in the dialog box that
appears.
