This chapter gives helpful information fo r what to do if you encounter an error.
This chapter includes:
• Tips for avoiding paper jams
• Clearing paper jams • Solving other problems
TIPS FOR AVOIDING PAPER JAMS
By selecting the correct media type
s, most paper jams can be avoided. 
When a paper jam occurs, follow the steps outlined on page 33. 
• Follow the procedures on page 21. En sure that the adjustable guides 
are positioned correctly.
• Do not overload the tray. Ensure that  the paper level is below the paper 
capacity mark on the inside of the tray.
• Do not remove paper from the tray  while your machine is printing.
• Flex, fan, and straight en 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 Printing on special print 
medias on page 22.)
• Ensure that the recommended side of  the print media is facing up in the 
tray.
If a paper jam occurs, the error LED on the control panel lights  orange. Find 
and remove the jammed paper. 
To resume printing after clearing paper jams, you must open and close the 
front cover.
CLEARING PAPER JAMS
In the paper exit area
1. If the paper jams as it exits to the output tray and a long portion of the 
paper is visible, pull t he paper straight out. 
When you pull the jammed paper, if  there is resistance and the paper 
does not move immediately, stop  pulling. Continue with the next step.
Paper jams in this area may result in loose toner on the
page. If you get any toner on your clothes, wash them in cold
water as hot water will set the toner into the fabric.

2.Open the top cover and the inner cover.
3. Loosen the paper if it is caught in the heat rollers. Then pull  the paper 
gently out.  
 
4.Close the inner cover and the top cover. Printing resumes automatically. 
In the paper feed area
1.Remove any misfeed paper by pulling it  out by the visible edge from the 
tray. Make sure that all of the paper is properly aligned in the tray.
2. Open 
and close the front or top cover to resume printing the 
document from failed pages.
• When removing the jammed paper, be careful not to touch the  heat roller (located underneath the inner cover). It is hot and 
could cause burns!
• The top and inner cover themselves may also be hot due to 
the heat roller. Allow the mach ine to cool before opening the 
covers.
Failed pages will not reprint. Try printing the pages.

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 is not well  distributed, you can 
improve print quality by redistributing the toner. 
See page 27. If this does not improve the print 
quality, install a new toner cartridge or an 
imaging unit.
• 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 printing 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 Paper . Refer to the  Software section  
for details.
If these steps do not correct the problem, contact a

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 imaging unit and install a new  one. See page 30.
Toner smear• Clean the inside of the machine. See page 25.
• Check the paper type and quality. See page 18.
• Remove the imaging unit and install a new one. See page 30.
Vertical repetitive 
defectsIf marks repeatedly appear  on the printed side of 
the page at even intervals:
• The imaging unit 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.

39 _Troubleshooting
Background scatterBackground scatter result s 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 cove rs 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 ar e 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.
