PROBLEMS RELATED TO SCAN RESULTS
Problem
The scanned image is
clipped.
The quality of the
scanned image is
poor.
The scanned image is
blank.
The scanned image is
upside down or on its
side.
The [COLOR START]
key indicator is not lit.
Point to check
Is the original scan size setting smaller
than the actual original size?
Is the original printed matter such as a
book or magazine?
When scanning a color or grayscale
original, is the color mode set to
"Mono2"?
Is a destination included that has
[TIFF-S] selected for the format?
Is the original placed face up or face
down correctly?
Are Internet fax addresses included in
the transmission?
Are Internet fax or fax destinations
included?
Set the scan size to the actual original size.
If you have intentionally set a smaller size than the actual
original size, note carefully the placement position of the
selected scan size when placing the original. For example,
when scanning a 8-1/2" x 11" (A4) original using a
5-1/2" x 8-1/2" (B5) setting on the document glass, align
the original using the document glass scale at the left
center to fit the area you wish to scan into the
5-1/2" x 8-1/2" (B5) scanning area.

THE ORIGINAL ON THE DOCUMENT

When the original is printed matter, vertical patterns
(moiré) may occur. Select the [Exposure] key in the base
screen to open the exposure setting screen. The [Moiré
Reduction] checkbox appears in this screen. This

effect. (only in scan mode and USB memory scan mode)
It may also be possible to reduce the moiré effect by
changing the resolution setting or shifting the original (or
changing its angle) slightly on the document glass.
Setting the color mode to "Mono2" replaces the colors in
the original with either black or white. This is suitable for
text-only originals; however, for originals that contain
illustrations, it is best to use the [BLACK & WHITE START]
key with the color mode set to [Grayscale], or set the color
mode of the [COLOR START] key to [Full Color] or
[Auto]-[Grayscale] and then scan.
When a broadcast transmission is performed that
includes both scan mode destinations and Internet fax
destinations that have [TIFF-S] selected for the format,
the resolution will remain fixed at [200X200dpi] even if a
different resolution setting is selected. If you wish to
send an image scanned at high resolution to scan mode
destinations, send the image in a separate
transmission.
When using the document glass, the original must be
placed face down. When using the automatic document
feeder, the original must be placed face up.
When both scan mode and Internet fax destinations are
included in a broadcast transmission, the original
transmission orientation of Internet fax takes
precedence, and thus the file may not appear in the
correct orientation when viewed on a computer. In this
event, send the image to the scan mode destinations in
a separate transmission.
If Internet fax or fax destinations are included in the
destinations, only the [BLACK & WHITE START] key
can be used.
