Settings of Basic Setup Dialog Box
You can configure the following settings in the Basic
Setup dialog box.
User Preference
Click [Save] to open the [Save User Preference] dialog
box.
The [Save User Preference] dialog box saves the current
settings under an assigned name.
You can select the name of a saved set of user preferences
in the list box to load those settings into the dialog box.
IMPORTANT
Assigned names can consist of up to 32 characters.
Mode
Select the mode for scanned images.
Hint
• Advanced text enhancement modes are good for scanning
documents with a background color or design behind 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 seems to
best suit your document. We recommend confirming an image
by prescanning the first page.
• When saving an image file in JPEG format, select [256-level
Gray] or [24-bit Color].
[Black and White]
Use this mode to scan text and line drawing documents as
black and while (binary) images.
[Error Diffusion]
Use this mode to scan documents containing photos as
black and white (binary) images.
[Advanced Text Enhancement]
Use this mode to scan documents with a dark or non-
uniform (pattern) background.
Hint
• If the background is uniform, it is removed where it surrounds
the text.
• If the background is non-uniform, such as a pattern, it is
processed to enhance text readability.
[Advanced Text Enhancement II]
Use this mode to scan documents with a light uniform
background and low-contrast text.
Hint
• The background in tight spaces around text may not be
removed.
• Documents with low-contrast text can be made more readable
by adjusting the contrast.
• If the background is non-uniform, such as a pattern, the
background remains visible in the image, and text may be
hard to read.
[256-level Gray]
Scans documents such as photos as grayscale images.
[24-bit Color]
Scans documents such as color photos as full-color
images.
