Tips for avoiding paper jams
By selecting the correct media types, most paper jams can be avoided. 
When a paper jam occurs, follow the steps outlined on page 7.1. 
• Follow the procedures on page 4.4. Ensure that the adjustable guides 
are positioned correctly.
• Do not overload the tray.
• Do not remove paper from the tray while your machine is printing.
• Flex, fan, and straighten paper before loading. 
• Do not use creased, damp, or highly curled paper.
• Do not mix paper types in a tray.
• Use only recommended print media. (
See Specifications on print 
media on page 4.2.)
• Ensure that the recommended side of the print media is facing up in 
the tray.
Clearing paper jams
Note
When removing paper that is jammed in the printer, if 
possible always pull the paper in the direction that it 
normally moves so as not to damage internal components. 
Always pull firmly and evenly; do not jerk the paper. If the 
paper tears, ensure that all fragments of paper are 
removed; otherwise a jam will occur again
.
If a paper jam occurs, the Status LED on the control panel lights red. Find 
and remove the jammed paper. 
To resume printing after clearing paper jams, you must open and close 
the front cover or rear cover.

Printing quality problems
If the inside of the machine is dirty or paper has been loaded improperly, 
you may notice a reduction in print quality. See the table below to clear 
the problem. Yo u r  
machine 
has an odd 
smell 
during initial 
use.The oil used to 
protect the fuser is 
evaporating.After printing about 100 color 
pages, there will be no more 
smell. It is a temporary issue.
ConditionSuggested solutions
Light or faded printIf a vertical white streak or faded area appears 
on the page:
• The toner supply is low. You may be able to 
temporarily extend the toner cartridge life. If 
this does not improve the print quality, install 
a new toner cartridge.
• The paper may not meet paper 
specifications; for example, the paper may 
be too moist or rough. (See Specifications 
on print media on page 4.2.)
• If the entire page is light, the print resolution 
setting is too low or the toner save mode is 
on. Adjust the print resolution and turn the 
toner save mode off. See the help screen of 
the printer driver and refer to Software 
section, respectively.
• A combination of faded or smeared defects 
may indicate that the toner cartridge needs 
cleaning. Contact a service representative.
• The surface of the LSU part inside the 
machine may be dirty. Clean the LSU, 
contact a service representative. 
Toner specks• The paper may not meet specifications; for 
example, the paper may be too moist or 
rough. (See Specifications on print 
media on page 4.2.)
• The paper transfer belt may be dirty. Clean 
the inside of your machine. Contact a 
service representative.
• The paper path may need cleaning. Contact 
a service representative.
ConditionPossible causeSuggested solutions
DropoutsIf faded areas, generally rounded, or broken 
texts or lines occur randomly on the page:
• A single sheet of paper may be defective. 
Try reprinting the job.
• The moisture content of the paper is uneven 
or the paper has moist spots on its surface. 
Try a different brand of paper. (See 
Specifications on print media on page 4.2.)
• The paper lot is bad. The manufacturing 
processes can cause some areas to reject 
toner. Try a different kind or brand of paper.
•
Change the printer option and try again. Go to 
printer properties, click 
Paper tab, and set paper 
type to 
Thick. Refer to the Software Section 
for details.
• Increase the level of the contrast of each 
color. To adjust the color contrast, click Start 
> Programs or All Programs > your printer 
driver name > Smart Panel and select 
Printer Setting > Graphic > Color and 
then click the Color Adjustment button. 
After Manual Color Adjustment window 
opens, move the scroll bar to the right 
direction. When finished, click Apply and 
then exit Smart Panel.
• If these steps do not correct the problem, 
contact a service representative.
White Spots White spots appear on the page:
• The paper is too rough and a lot of dirt from 
the paper falls to the inner devices within 
the machine, which means the transfer belt 
may be dirty. Clean the inside of your 
machine. Contact a service representative.
• The paper path may need cleaning. Contact 
a service representative.
Vertical linesIf black vertical streaks appear on the page:
• The toner cartridge has probably been 
scratched. Remove the toner cartridge and 
install a new one.

Color or Black 
backgroundIf the amount of background shading becomes 
unacceptable:
• Change to a lighter weight paper. (See 
Specifications on print media on page 4.2.)
• Check the environmental conditions: very 
dry conditions (low humidity) or a high level 
of humidity (higher than 80% RH) can 
increase the amount of background 
shading.
• Remove the old toner cartridge, and then 
install a new one. (See Replacing the toner 
cartridge on page 6.4.)
Toner smear• Clean the inside of the machine. Contact a 
service representative to clean the inside of 
the machine.
• Check the paper type and quality. (See 
Specifications on print media on page 4.2.)
• Remove the paper transfer belt, and then 
install a new one. (See Replacing the toner 
cartridge on page 6.4.)
Vertical repetitive 
defectsIf marks repeatedly appear on the printed side 
of the page at even intervals:
• Clean the inside of the machine. Contact a 
service representative to clean the inside of 
the machine. After cleaning the inside of the 
machine, if you still have the same 
problems, install a new toner cartridge of the 
problem color. See Replacing the toner 
cartridge on page 6.4.
• Parts of the machine may have toner on 
them. If the defects occur on the back of the 
page, the problem will likely correct itself 
after a few more pages.
• The fusing assembly may be damaged. 
Contact a service representative.
ConditionSuggested solutions
Background scatterBackground scatter results from bits of toner 
randomly distributed on the printed page. 
• The paper may be too damp. Try printing 
with a different batch of paper. Do not open 
packages of paper until necessary so that 
the paper does not absorb too much 
moisture.
• If background scatter occurs on an 
envelope, change the printing layout to 
avoid printing over areas that have 
overlapping seams on the reverse side. 
Printing on seams can cause problems.
• If background scatter covers the entire 
surface area of a printed page, adjust the 
print resolution through your software 
application or in printer properties.
Misformed 
characters• If characters are improperly formed and 
producing hollow images, the paper stock 
may be too slick. Try different paper. (See 
Specifications on print media on page 4.2.)
• If characters are improperly formed and 
producing a wavy effect, the scanner unit 
may need service. Contact a service 
representative.
Page skew• Ensure that the paper is loaded properly.
• Check the paper type and quality. (See 
Specifications on print media on page 4.2.)
• Ensure that the paper or other material is 
loaded correctly and the guides are not too 
tight or too loose against the paper stack.
Curl or wave• Ensure that the paper is loaded properly.
• Check the paper type and quality. Both high 
temperature and humidity can cause paper 
curl. (See Specifications on print media on 
page 4.2.)
• Turn the stack of paper over in the tray. Also 
try rotating the paper 180° in the tray.

I encounter error 
“Unable to open mfp

printing a document.Please avoid changing print job 
parameters (via LPR GUI, for example) 
while a print job is in progress. Known 
versions of CUPS server break the print 
job whenever print options are changed 
and then try to restart the job from the 
beginning. Since Unified Linux Driver locks 
mfp port while printing, the abrupt 
termination of the driver keeps the port 
locked and therefore unavailable for 
subsequent print jobs. If this situation 
occurred, please, try to release the mfp 
port.
