Problem 4 Documents are not scanned according to the
settings configured in the scanner driver.
Solutions When you scan using [Select document] panel
registered with CaptureOnTouch, the CaptureOnTouch
settings have priority over the scanner driver settings.
Edit settings in the [Select document] panel, or create a
new [Select document] panel using the desired
scanning conditions.
Problem 5 If white lines or streaks appear in scanned images.
Solutions Clean the scanning glass (both sides) and the feed and
retard 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.
Problem 6 Scanned images are too dark (or light).
Solutions The brightness setting may need adjustment. Adjust the
[Brightness] setting on the [Brightness] tab sheet of the
scanner driver: higher if the images are too dark, and
lower if too light.
Problem 7 Text or images bleed through from the back side of
documents to appear in scanned images.
Solutions (1) Increase the [Brightness] setting on the scanner
driver's [Brightness] tab sheet. Alternatively, enable
the "Prevent Bleed Through/Remove Background"
setting.
(2) If the paper is very thin, photocopy the original and
scan the copy.
Problem 8 Duplex (two-sided) scanning is not possible.
Solutions Duplex scanning is not possible if the Scanning Side
setting is set to [Simplex]. On the scanner driver's
[Basic] tab sheet, set [Scanning Side] to [Duplex]. If
Scanning Side is set to [Skip blank page], images of
blank pages are not saved.
Problem 9 A black margin appears around scanned document
images.
Solutions A black margin appears when a document smaller than
the preset papersize is scanned, or when the loaded
document has shifted out of position. Make the following
scanner driver settings.
(1) On the [Basic] tab sheet, set the [Page Size] to
[Match original size].
(2) Adjust the margin setting in the minus direction
([Basic tab] – [Page Size] – [Page Size Settings] –
[Scan Area] tab)
(3) Enable [Border Removal] ([Image processing] tab –
[Border Removal])
