Printed images 
contain blots or 
are patchy.
The paper is 
creased, curled, 
or has blemishes.Smooth out the wrinkles from the paper, or replace it. See 
“Copy Paper”, About This Machine.
The image is too 
dark or too light.The correct pa-
per type set-
tings are not 
made.Check the paper loaded on the paper tray or bypass tray 
matches the paper type set on the display panel. See 
“Copy Paper”, About This Machine.
The image is too 
dark or too light.The paper is 
loaded reverse 
side up.Before printing on special paper, check its surface careful-
ly. Printing on non-print surfaces reduces print quality 
and can damage the machines internal components. See 
“Copy Paper”, About This Machine.

There is considera-
ble delay between 
the print start in-
struction and actu-
al printing.Processing time 
depends on 
data volume. 
High volume 
data, such as 
graphics-heavy 
documents, 
takes longer to 
process.If the Data In indicator is blinking, data has been received 
by the machine. Wait for a while.
Making the following setting on the printer driver may re-
duce the computers workload.

5. Troubleshooting When
Using the Scanner Function
This chapter describes likely causes of and possible solutions for scanner func-
tion problems.
When Scanning Is Not Done As Expected
This section describes causes and remedies when scan results are not as expect-
ed.
Problem Cause Solution
The scanned image is 
dirty.The exposure glass, scanning 
glass, exposure glass cover or 
ARDF is dirty.Clean these parts. See p.89 “Main-
taining Your Machine”.
The image is distorted 
or out of position.The original was moved during 
scanning.Do not move the original during 
scanning.
The image is distorted 
or out of position.The original was not pressed flat 
against the exposure glass.Make sure that the original is 
pressed flat against the exposure 
glass.
The scanned image is 
upside down.The original was placed upside 
down. Place the original in the correct 
orientation. See “Placing Origi-
nals”, Copy Reference.
No image results from 
scanning.The original was placed with the 
front and back reversed.When the original is placed di-
rectly on the exposure glass, the 
side to be scanned must face 
down. When the original is fed 
via the ARDF, the side to be 
scanned must face up. See “Plac-
ing Originals”, Copy Reference.
Images are scanned in 
rotated orientation.If you set the original with its up-
per edge backward and save grey 
scale images as a TIFF or JPEG 
file, they are scanned in rotated 
orientation. If you select [Top to Bottom] for 
one- or two-sided originals, 
place your originals upper 
edge first in the ARDF.
 If you select [Top to Top] for 
two-sided originals, select 
[Single Page:PDF] or [Multi-
page:PDF] for [File Type Priority].
The scanned image 
contains white spaces.If you scan originals using func-
tions other than the network 
TWAIN scanner function, certain 
paper size and resolution settings 
may produce scanned images 
that are larger than the specified 
size because of margins being 
added to the sides.Scanning at a higher resolution 
may reduce the margins.

5When You Cannot Send Scanned Files
The following sections describe likely causes of and solutions for network deliv-
ery and e-mail sending-related problems.
When You Cannot Browse the Network to Send a Scanned File
This section describes likely causes of and possible solutions for the browser net-
work failing to operate when files are sent.
When the TWAIN Driver Cannot Be Started
This section describes likely causes of and possible solutions for the TWAIN
driver failing to operate.
The Network Delivery Function Cannot Be Used
This section describes likely causes of and possible solutions for the Network
Delivery function failing to operate.
Problem Cause Solution
The network cannot be 
browsed when specify-
ing the destination 
folder.The following machine settings 
may not be correct:
 IPv4 address
 Subnet MaskCheck the settings. See “Network 
Settings”, General Settings 
Guide.
Problem Cause Solution
The Scanner Properties 
dialog box cannot be 
displayed.Advanced encryption has been 
specified in the extended security 
setting.
For details about the extended securi-
ty setting, contact the administrator.
Problem Cause Solution
The network delivery 
function cannot be 
used.The delivery software may be an 
old version or a security setting 
may be specified.Contact the administrator.
The network delivery 
function cannot be 
used.The network delivery function 
setting is not correct.Specify it correctly. See “Settings 
Required to Use the Network De-
livery Scanner”, General Settings 
Guide.
