■ Checking the basic Scanning Conditions
When scanning the documents, make sure to set the "Color
mode", "Paper Size", "Dots per inch", and "Scanning Side"
in the basic conditions on the "Basic" tab.
Color mode
Select the mode for scanned images.
Hint
• Some functions are limited depending on the color mode
setting.
• Advanced text enhancement modes are useful if you want to
scan documents with a background color or design behind the
text as black-and-white images, and remove or process the
surrounding background to enhance the text for easy reading.
• Two advanced text enhancement modes are provided to suit
different background types. Select the mode that best suits
your document. We recommend confirming the image by
prescanning the first page.
• When saving an image file in JPEG format, select [256-level
Gray] or [24-bit Color].
Page Size
Select the page size of the document to be scanned.
IMPORTANT
• Select [Match original size] to scan the following types of
documents.
– Documents of a non-standard size
– Documents containing pages of different sizes
– When using the Long Document mode (See “Long
Document Mode Setting” on p. 3-3.)
• When [Match original size] is selected, the area settings in the
Scan Area dialog box are disabled.
• The [Match original size] process may malfunction in the
following situations. If this occurs, select a standard size
(such as [A4] or [Letter]), or click the [Area] button to create a
custom page size.
– When scanning a page with a dark area at the left or right
edge
– When scanning a glossy or reflective document
– When the brightness setting is incorrect
– When the Custom setting is selected in the Gamma Settings
dialog box
• Depending on the application program, operation may
become unstable when [Match original size] is enabled. In
that case, [Match original size] should be disabled.
Dots per inch
Select the scanning resolution.
Hint
• Higher resolutions provide clearer images, but produce larger
files.
• The [Moire Reduction] setting is enabled when the resolution
is set to 300 dpi or lower, and the [Image Quality] setting is
enabled when the resolution is set to 400 or 600 dpi.
Scanning Side
Select which page side(s) to scan.
Hint
• Select [Skip blank pages] to delete the blank page images
before saving.
