Tips for Avoiding Paper Jams
By selecting the correct paper types, most paper jams can be 
avoided. If a paper jam occurs, follow the steps outlined in 
“Clearing Paper Jams” on page 6.3. 
• Follow the procedures on page 3.2. Ensure that the adjustable guides are positioned correctly.
• Do not overload the tray.
• Do not remove the paper from the tray while printing.
• Flex, fan, and straighten the paper before loading. 
• Do not use creased, damp, or highly curled paper.
• Do not mix paper types in a tray.
• Use only recommended print materials. See “Paper  Specifications” on page 8.1.
• Ensure that the recommended print side of print materials is  facing up in the tray.Solving Print Quality Problems
Dirt inside of the printer or improper paper loading may reduce 
print quality. See the table below to troubleshoot problems. 
ProblemSolution
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 
“Redistributing Toner” on page 5.2. If this does not 
improve 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 
“Paper Specifications” on page 8.1.
• A combination of faded or smeared defects may  indicate that the printer needs cleaning. See 
page 5.7.
Toner specksThe paper may not meet specifications (for example, 
the paper is too moist or too rough). See “Paper 
Specifications” on page 8.1.
DropoutsIf generally rounded, faded areas 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 “Paper Specifications” on 
page 8.1.
• The paper lot is bad. The manufacturing process  can cause some areas to reject toner. Try a different 
kind or brand of paper.
• The toner cartridge may be defective. See “
Ve r t i c a l  
repetitive defects
” on the next page.
• 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.
• If these steps do not correct the problems, contact  a service representative.

Vertical linesIf black vertical streaks appear on the page:
• A imaging unit has probably been scratched. Remove the imaging unit and install a new one. See 
page 5.3. 
If white vertical lines appear on the page:
• Clean the inside of the printer. See “Cleaning the  Inside of the Printer” on page 5.7. If you still have 
the same problems, replace the imaging unit with a 
new one. See page 5.3. 
Color or Black 
backgroundIf the amount of background shading becomes 
unacceptable, the procedures below may fix the 
problem.
• Change to lighter weight paper. See “Paper 
Specifications” on page 8.1.
• Check the printer’s environment; very dry (low  humidity) or high humidity (higher than 80% RH) 
conditions can increase the amount of background 
shading.
• Remove one of the old toner cartridges and install a 
new one.
Toner smear• Clean the inside of the printer. See “Cleaning the Inside of the Printer” on page 5.7
• Check the paper type and quality. See “Paper  Specifications” on page 8.1.
• Remove the imaging unit and install a new one. See 
“Replacing the Imaging Unit” on page 5.4.
Vertical 
repetitive 
defectsIf marks repeatedly appear on the printed side of the 
page at even intervals:
• Clean the inside of the printer. See “Cleaning the Inside of the Printer” on page 5.7. After cleaning 
the inside of the printer, if you still have the same 
problems, install a new toner cartridge of the 
problem color. See “Replacing Toner Cartridges” on 
page 5.3.
• Parts of the printer 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 
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 via the printer 
properties window.
Misformed 
characters• If characters are improperly formed and producing  hollowed images, the paper stock may be too slick. 
Try a different paper. See “Paper Specifications” on 
page 8.1.
• If characters are improperly formed and producing 
a wavy effect, the printer may need service. Verify 
that it also occurs on a demo page. See page 2.7. 
For service, contact a service representative.
Page skew• Ensure that the paper is loaded properly.
• Check the paper type and quality. See “Paper Specifications” on page 8.1.
• 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 high humidity can cause paper 
curl. See “Paper Specifications” on page 8.1.
• Turn the stack of paper over 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 “Paper Specifications” on page 8.1.
• Turn the stack of paper over in the tray. Also try  rotating the paper 180° in the tray.
