document glass. Place originals in the document feeder 
tray of the automatic document feeder.
Did you place an original that is folded? If a folded original is placed in the automatic document 
feeder, an error will occur and scanning will be 
cancelled when the actual original size is detected 
during scanning.
Following the instructions in the display, unfold the 
original, place it in the automatic document feeder

attachment limit set in the system 
settings (administrator)?If your administrator has set a limit on the size of 
transmitted files, a file that exceeds the limit cannot be 
transmitted. Check with your administrator.
Did the image file exceed the file 
attachment size limit of your mail 
server?
(When Scan to E-mail is used.)Reduce the size of the file attachment (reduce the 
number of pages scanned). The size of the file can also 
be reduced by scanning using a lower resolution setting. 
Ask your mail server administrator what the file size limit 
is for one e-mail transmission.
Has the folder on the destination 
computer been set as a shared folder so 
that files can be sent to it?
(When using Scan to Network Folder.)If the destination folder is not configured as a shared 
folder, select share in the folder properties. If the folder 
was moved or otherwise changed, the share setting 
may have been cancelled.
Is IPsec Settings enabled on the

(When using Scan to Network Folder.)When IPsec Settings is enabled in the system settings

Transmission takes a 
long time.Is the resolution setting appropriate at 
the time of scanning?To select resolution and data compression settings that 
are suited to the purpose of transmission and create 
image data that is balanced in terms of resolution and 
file size, pay attention to the following points:
Resolution settings
The default resolution setting is [200X200dpi] in 
scanner and USB memory mode, and [200X100dpi] in 
Internet fax mode. If the original does not contain a 
halftone image such as a photo or illustration, 
scanning at the default resolution will create a 
practical and useful image. A higher resolution setting 
or the Half Tone setting (in Internet fax mode) 
should only be selected if the original contains a photo 
and you wish to give priority to the quality of the photo 
image. Exercise caution in this case as a larger file 
will be created than when the default setting is used.
A destination is 
pre-selected.Is Default Address Setting enabled in 
the system settings (administrator)?If you wish to send to a destination other than the 
default destination, touch the [Cancel] key.
If you are the administrator and wish to change or 
disable the default destination, change the settings as 
appropriate in Default Address Setting.

PROBLEMS RELATED TO SCAN RESULTS
ProblemPoint to checkSolution
The scanned image is 
clipped.Is the original scan size setting smaller 
than the actual original size?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 an 
A4 (8-1/2 x 11) original using a B5 (5-1/2 x 8-1/2) 
setting on the document glass, align the original using 
the document glass scale at the left edge to fit the area 
you wish to scan into the B5 (5-1/2 x 8-1/2) scanning 
area.
☞1. BEFORE USING THE MACHINE PLACING 
THE ORIGINAL ON THE DOCUMENT GLASS 
(page 1-40)
The quality of the 
scanned image is 
poor.Is the original printed matter such as a 
book or magazine?When the original is printed matter, vertical patterns 
(moiré) may occur. Touch the [Exposure] key in the base 
screen to open the exposure setting screen. The [Moiré 
Reduction] checkbox appears in this screen. This 
checkbox can be selected   to reduce the moiré 
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.
When scanning a colour or greyscale 
original, is the colour mode set to 
Mono2?Setting the colour mode to Mono2 replaces the colours 
in the original with either black or white. This is suitable 
for text-only documents. To scan a document that 
includes illustrations or other images, set the colour 
mode to [Greyscale] or [Full Colour].
Is a destination included that has 
[TIFF-S] selected for the format?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.
The scanned image is 
blank.Is the original placed face up or face 
down correctly?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.
The scanned image is 
upside down or on its 
side.Are Internet fax addresses included in 
the transmission?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.
The scanned image is 
black and white.Are Internet fax or fax destinations 
included?If Internet fax or fax destinations are included, scanning 
will only take place in black and white.
