3 Other Printing Problems
This section explains likely causes of and possible solutions for problems that
can occur when printing from a computer.
Problem Cause Solution
Print is smudges. Settings for thick pa-
per have not been 
made when printing 
on thick paper in the 
bypass tray. PCL 5e/6 and PostScript 3
Select [Thick] in the [Type:] list on the [Paper] 
tab.

page is faded.When D is blinking, 
toner is beginning to 
run out.Add toner. See p.77 “Adding Toner”.
The print on the entire 
page is faded.The paper is damp. Use paper that has been stored in the recom-
mended temperature and humidity condition. 
See “Copy Paper”, About This Machine.
The print on the entire 
page is faded.The paper is unsuita-
ble.Use the recommended paper. (Printing on 
coarse or treated paper might result in faint 
print image.) See “Copy Paper”, About This 
Machine.
The print on the entire 
page is faded.If the [Toner saving] 
check box is selected 
in the printer driver 
settings, the entire 
page will be faded 
when printed.For the RPCS printer driver, [Toner saving] is lo-
cated on the [Print Quality] tab. For the Post-
Script 3 printer driver, see PostScript 3 
Supplement. See the printer driver Help.
Image bleeds when 
rubbed.If you are using thick 
paper, [Paper type:] 
might not be set to 
[Thick].On the printer drivers [Setup] tab, set [Paper 
type:] to [Thick]. See the printer driver Help.
Paper is not fed from 
the selected tray.When you are using a 
Windows operating 
system, printer driver 
settings override 
those set using the 
display panel. Set the desired input tray using the printer 
driver. See the printer driver Help.
The printed image is 
different from the im-
age on the computers 
display.With certain func-
tions, such as enlarge-
ment and reduction, 
image layout might 
be different to that on 
the computer display.In the application, change the layout, character 
size, and character settings.
The printed image is 
different from the im-
age on the computers 
display.You might have se-
lected to replace True 
Type fonts with ma-
chine fonts in the 
printing process.To print an image similar to that of the compu-
ter display, make settings to print True Type 
fonts as an image. See the printer driver Help.

in at a slant.Load the paper correctly. See p.65 “Loading 
Paper”.
Misfeeds occur fre-
quently.The number of sheets 
loaded exceeds the ca-
pacity of the machine.Load paper only as high as the upper limit 
markings on the side fence of the paper tray or 
bypass tray. See “Copy Paper”, About This 
Machine.
Misfeeds occur fre-
quently.The paper is damp. Use paper that has been stored in the recom-
mended temperature and humidity condition.

White lines appear. When D is blinking, 
toner is beginning to 
run out.Add toner. See p.77 “Adding Toner”.
When printing graph-
ics, the output and the 
screen are different.If the printer driver is 
configured to use the 
graphics command, 
the graphics com-
mand from the ma-
chine is used to print.If you want to print accurately, set the printer 
driver to print without using the graphics 
command. See the printer driver Help.
Garbled characters 
are printed.The correct printer 
language might have 
not been selected.Set the correct printer language.
Images are printed in 
the wrong orienta-
tion.The feed orientation 
you selected and the 
feed orientation select-
ed in the printer driv-
ers option setup might 
not be the same.Set the machines feed orientation and the 
printer drivers feed orientation accordingly. 
See the printer driver Help.
There is considerable 
delay between the 
print start instruction 
and actual printing.“Off mode / Sleep 
mode” might be set.The machine requires time to warm up if it has 
been in “Off mode/Sleep mode”. Specify “Off 
mode/Sleep mode” in [System Settings], [Auto 
Off Timer]. Problem Cause Solution

4. Troubleshooting When
Using the Scanner Function
This chapter explains likely causes of and possible solutions for scanner function
problems.
When Scanning is Not Done as Expected
This section explains causes and remedies when scan results are not as expected.
Problem Cause Solution
The scanned image is 
dirty.The exposure glass or auto docu-
ment feeder (ADF) is dirty.Clean these parts. See p.106 
“Maintaining 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/Document Server 
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 ADF, the side to be 
scanned must face up. See “Plac-
ing Originals”, Copy/Document 
Server Reference.
Images are scanned in 
rotated.If you set the original with its up-
per edge backward and save full 
colour/grey scale images as a 
TIFF or JPEG file, they are 
scanned in rotated.When placing a stack of originals 
in the ADF, place their upper 
edges first.
The scanned image 
contains white spaces. If you scan originals using 
functions other than the net-
work TWAIN scanner func-
tion, certain paper size and 
resolution settings may pro-
duce scanned images that are 
larger than the specified size 
because of margins being 
added to the sides.
 If the File Format Converter 
(optional ) is installed, the 
margins may become wider.Scanning at a higher resolution 
may reduce the margins.
