Solving Problems

If 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. 

If 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.

• Clean the inside of the printer. See “Cleaning the 

• Check the paper type and quality. See “Paper 

Specifications” on page 8.1.

• Remove the imaging unit and install a new one. See 

If 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 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.

• 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.

• Ensure that the paper is loaded properly.
• Check the paper type and quality. See “Paper 

• Ensure that the paper or other material is loaded 

correctly and the guides are not too tight or too 

loose against the paper stack.

• 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.
