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.
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. See 
page 27. If this does not improve the print 
quality, install a new toner cartridge.
• The paper may not meet paper specifications; 
for example, the paper is too moist or too 
rough. See page 18.
• If the entire page is light, the print resolution 
setting is too low. Adjust the print resolution. 
See the help screen of the printer driver.
• A combination of faded or smeared defects 
may indicate that the toner cartridge needs 
cleaning.
• The surface of the LSU part inside the machine 
may be dirty. Clean the LSU by opening and 
closing the front cover several times and if the 
problem still occurs call the contact a service 
representative.
Toner specks• The paper may not meet specifications; for 
example, the paper is too moist or too rough. 
See page 18.
• The paper path may need cleaning. See 
Cleaning the inside on page 25.
DropoutsIf faded areas, generally rounded, 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 page 18.
• 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 type 
to Thick. Refer to the Software section for 
details.
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 white vertical streaks appear on the page:
• The surface of the LSU part inside the machine 
may be dirty. Clean the LSU by opening and 
closing the front cover several times and if the 
problem still occurs contact a service 
representative.
Black backgroundIf the amount of background shading becomes 
unacceptable:
• Change to a lighter weight paper. See page 18.
• Check the machine’s environment: very dry 
(low humidity) or high humidity (higher than 
80% RH) conditions can increase the amount 
of background shading.
• Remove the old toner cartridge and install a 
new one. See page 28.
Toner smear• Clean the inside of the machine. See page 25.
• Check the paper type and quality. See page 18.
• Remove the toner cartridge and install a new 
one. See page 28.
Vertical repetitive 
defectsIf marks repeatedly appear on the printed side of 
the page at even intervals:
• The toner cartridge may be damaged. If a 
repetitive mark occurs on the page, print a 
cleaning sheet several times to clean the 
cartridge. After the printout, if you still have the 
same problems, remove the toner cartridge and 
install a new one. See page 28.
• 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.

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 
the printer properties.
Misformed 
characters• If characters are improperly formed and 
producing hollow images, the paper stock may 
be too slick. Try a different paper. See page 18.
Page skew• Ensure that the paper is loaded properly.
• Check the paper type and quality. See page 18.
• 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 page 18.
• Turn over the stack of paper in the tray. Also try 
rotating the paper 180° in the tray.
Wrinkles or creases• Ensure that the paper is loaded properly.
• Check the paper type and quality. See page 18.
• Turn over the stack of paper in the tray. Also try 
rotating the paper 180° in the tray.

Character VoidsCharacter voids are white areas within parts of 
characters that should be solid black:
• If you are using transparencies, try another 
type of transparency. Because of the 
composition of transparencies, some character 
voids are normal. 
• You may be printing on the wrong surface of 
the paper. Remove the paper and turn it 
around. 
• The paper may not meet paper specifications. 
See page 18.
Horizontal stripesIf horizontally aligned black streaks or smears 
appear:
• The toner cartridge may be installed 
improperly. Remove the cartridge and reinsert 
it.
• The toner cartridge may be defective. Remove 
the toner cartridge and install a new one. See 
page 28.

The machine does 
not print.• Check if the printer driver is installed in your 
system. Open Unified Driver Configurator 
and switch to the Printers tab in Printers 
configuration window to look at the list of 
available printers. Make sure that your 
machine is displayed on the list. If not, 
please, invoke Add new printer wizard to set 
up your device. 
• Check if the printer is started. Open Printers 
configuration and select your machine on the 
printers list. Look at the description in the 
Selected printer pane. If its status contains 
“(stopped)” string, please, press the Start 
button. After that normal operation of the 
printer should be restored. The stopped 
status might be activated when some 
problems in printing occurred. 
• Check if your application has special print 
option such as “-oraw”. If “-oraw” is specified 
in the command line parameter then remove 
it to print properly. For Gimp front-end, select 
“print” -> “Setup printer” and edit command 
line parameter in the command item.
The machine does 
not print whole pages 
and its output is half 
page printed.The problem is solved in AFPL Ghostscript v. 
8.52 or above. Download the latest version of 
AFPL Ghostscript from http://sourceforge.net/
projects/ghostscript/ and install it to solve this 
problem.
I encounter error 
“Unable to open mfp 
port device file!” 
when 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.
