PROBLEMS WHEN THE NETWORK 
SCANNER FUNCTION IS USED
If a problem or question arises, try to solve the situation using the following information before contacting your 
authorised service representative.
ProblemCause and solutionPage
The image cannot be scanned.
The original is loaded upside down.
→If you are using the document glass, the original must be placed 
face down. If you are using the RSPF, the original must be 
inserted face up.72
A moiré (stripe pattern) appears on 
the scanned image.
A slight amount of moiré sometimes appears when 
printed matter is scanned.
→Moiré can in some cases be reduced by changing the scanning 
resolution.
If you are using the document glass, also try shifting the position 
and/or angle of the original on the document glass.80
The scanned image is fuzzy or has 
smudges.
The document glass or the underside of the RSPF (or 
document cover) is dirty.
→To clean the document glass and the underside of the document 
cover, see operation manual for copier.—
The scanned image is clipped.
The set original scanning size is smaller than the actual 
original size.
→Set the actual original size.
If you intentionally selected a size setting smaller than the actual 
original size, take into consideration the part of the original that 
you wish to scan when placing the original. For example, if the 
actual size is A4 (8-1/2 x 11) and you selected A5 
(5-1/2 x 8-1/2) for the size setting, place the original so that the 
part that you wish to scan is within the A5 (5-1/2 x 8-1/2) area 
indicated by the guides on the far left side of the document glass.
78
The scanned image is upside down 
or on its side.
The original was not placed in the correct orientation.
→Place the original in the correct orientation. (See operation 
manual for copier)
To rotate the image 90 degrees, touch the [ORIGINAL] key in the 
initial screen and then touch the ROTATE THE IMAGE 90 
DEGREES checkbox to make a checkmark appear.
78
The received image data cannot be 
opened.
The viewer program used by the recipient does not 
support the format of the received image data.
→Try selecting a different file type (TIFF or PDF) and/or a different 
compression format (NONE, MH (G3), MMR (G4)) when sending 
the image data.
Otherwise, have the recipient use Sharpdesk or a viewer 
program that supports the above combinations of file types and 
compression formats.
81
When the same file name is used for 
two successive Scan to FTP 
transmissions, the second file is not 
sent.The first file may still remain in the cache of the file server 
client. Disable use of the cache in the client software.

TROUBLESHOOTING AND MAINTENANCE
The recipient does not receive 
transmitted data.
An incorrect destination was selected.
Otherwise, there is a mistake in the information stored 
for the destination (e-mail address or FTP server 
information).
→Select the correct destination and make sure the correct 
information is stored for the destination.
* If delivery by e-mail (Scan to E-mail) is unsuccessful, an 
error message such as Undelivered Message may be 
sent to the designated administrators e-mail address. 
This information may help you determine the cause of 
the problem.62 - 65
The recipient does not receive data 
sent by e-mail (Scan to E-mail).
Check the Web page to see if a limit has been set for the size 
of image files sent using Scan to E-mail (the factory default 
setting is Unlimited).
A limit can be set from 1 MB to 10 MB. Consult the 
administrator of the Web page to select a suitable limit.58
The amount of data that can be sent in one e-mail 
transmission is sometimes limited by the administrator of the 
mail server. Even if the amount of data sent is within the limit 
setting explained above, if it exceeds the limit set by the 
administrator of the mail server, the data will not be delivered 
to the recipient.
Decrease the amount of data sent in the e-mail transmission 
(reduce the number of pages scanned). (Ask your mail server 
administrator what the data limit is for one e-mail transmission.)
—
Transmission takes a long time.When there is a large amount of image information, the data 
file is also large and transmission takes a long time.—
In order to select image quality and data compression settings that are suited to the purpose 
of transmission and create image data that is well-balanced in terms of image quality and file 
size, pay attention to the following points:
Image quality modes (TEXT, TEXT/PHOTO, PHOTO)
The factory default setting is TEXT/PHOTO. If the original does not contain photographs, illustrations, or 
other halftone images, TEXT mode will give you the most workable scanned image. TEXT/PHOTO should 
only be selected when the original includes a photograph and you wish to give priority to the quality of the 
photograph. (There is no advantage to scanning a text-only original in TEXT/PHOTO or PHOTO mode.)
PHOTO mode should only be used to scan a photograph or illustration. Note that this will produce a larger file 
size than the other modes.
Resolution
The factory default setting is 300 dpi. This is suitable for originals with mixed text and 
illustrations/photographs; however, it produces a slightly larger file size. For normal text originals, a resolution 
setting of 200 dpi produces an image that is sufficiently readable. (200 dpi is equivalent to the Fine resolution 
setting of fax machines.)
The 600 dpi setting should only be used in cases where high-clarity image reproduction is required, such as an 
original that includes photographs or illustrations. Note that a high-resolution setting will result in a larger file 
size and transmission may not be successful if there is insufficient disk capacity in the server to which the 
image is sent (or if the administrator of the server has restricted the file size). If transmission is not successful, 
you can try such measures as reducing the number of scanned pages in the file or reducing the scan size 
setting for the original.

TROUBLESHOOTING AND MAINTENANCE
IF YOUR E-MAIL IS RETURNED
If a Scan to E-mail is not successfully transmitted, an e-mail informing you of this fact is sent to the sender selected 
at the time of transmission. If this happens, read the e-mail and determine the cause of the error, and then repeat 
the transmission.
IMPORTANT POINTS WHEN USING SCAN TO E-MAIL
Be very careful not to send image data files that are too large.
Your mail servers system administrator may have placed a limit on the amount of data that can be sent in one e-mail 
transmission. If this limit is exceeded, the e-mail will not be delivered to the recipient. Even if there is no limit and 
your e-mail is successfully delivered, a large data file may take a long time to be received and place a heavy burden 
on the recipients network, depending on the recipients network (Internet) connection environment.
If large image data files are repeatedly sent, the resulting burden on the network may slow down the speed of other, 
unrelated data transmissions and in some cases, may even cause the mail server or network to go down.
The images on the following page will produce the following file sizes when scanned as A4 or 8-1/2 x 11 size 
originals:
* If multiple images are scanned, the file size will be approximately (Size of each image as indicated above) x 
(Number of images scanned).
Although the actual limitation depends on your network environment, a general guideline for the maximum file size 
for Scan to E-mail is 2000 KB. In cases where you need to send multiple documents, try such measures as lowering 
the resolution mode.
Original image samples
The original images shown below are samples to help you understand the above explanations. Note that these
