Vertical lines

If black vertical streaks appear on the page:

 

 

 

 

 

 

• The imaging unit inside the printer has probably been

 

 

AaBbCc

 

 

 

 

 

 

 

 

scratched. Install a new imaging unit.

 

 

AaBbCc

 

 

 

If white vertical lines appear on the page:

 

 

AaBbCc

 

 

 

 

 

 

 

 

• The Laser Scanner window has probably been contaminated,

 

 

AaBbCc

 

 

 

 

 

 

 

 

clean the Laser Scanner window. Holding the end of the

 

 

AaBbCc

 

 

 

 

 

 

 

 

cleaner, slide it in and out several times. See “Cleaning the

 

 

 

 

 

 

LSU Inside the Printer” on page 6.30.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Color or Black

If the amount of background shading becomes unacceptable,

background

the procedures below may fix the problem.

 

 

 

 

 

 

• Change to lighter weight pages. See “Paper Specifications” on

 

AaBbCc

 

 

page D.4.

 

AaBbCc

 

 

• Check the printer’s environment; very dry (low humidity) or

 

AaBbCc

 

 

high humidity (higher than 80% RH) conditions can increase

 

 

 

the amount of background shading.

 

AaBbCc

 

 

 

 

 

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

 

AaBbCc

 

 

“Replacing the Imaging Unit” on page 6.14.

 

 

 

 

 

 

 

Toner smear

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

 

 

 

 

 

 

Printer” on page 6.31

 

 

 

 

 

 

• Check the paper type and quality. See “Paper Specifications”

 

 

 

 

 

 

on page D.4.

 

 

 

 

 

 

• Remove the transfer belt and install a new one. See “Replacing

 

 

 

 

 

 

the Transfer Belt” on page 6.22.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Vertical repetitive

If marks repeatedly appear on the printed side of the page at

 

 

defects

even intervals:

 

 

 

 

 

 

 

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

 

 

AaBbCc

 

 

 

 

Printer” on page 6.31. After cleaning the inside of the printer,

 

 

AaBbCc

 

 

 

 

if you still have the same problems, install a new toner

 

 

AaBbCc

 

 

 

cartridge of defected color. See “Replacing the Toner

 

 

 

 

 

Cartridges” on page 6.8.

 

 

AaBbCc

 

 

 

 

• Parts of the printer may have toner on them. If the defects

 

 

 

 

 

 

 

 

AaBbCc

 

 

 

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.
