Troubleshooting_ 58

If the inside of the machine is dirty or paper has been loaded improperly, 

there might be a reduction in print quality. See the table below to clear the 

problem. 

•

If 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 52.) If this does not improve the print 

quality, install a new toner cart

•

The paper may not meet paper specifications; 

for example, the paper may be too moist or 

•

If the entire page is light, the print resolution 

setting is too low or the toner save mode is 

on. Adjust the print resolution and turn the 

toner save mode off. See the help screen of 

the printer driver.

•

A combination of faded or smeared defects 

may indicate that the toner cartridge needs 

cleaning. (See "Cleaning the inside" on 

•

The surface of the LSU part inside the 

machine may be dirty. (See "Cleaning the 

•

The paper may not meet specifications; for 

example, the paper may be too moist or 

•

The transfer roller may be dirty. Clean the 

inside of your machine. Contact a service 

representative.

•

The paper path may need cleaning. Contact a 

service representative.

If 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 "Print 

•

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 Printing Preferences, click Paper tab, 

and set type to Thick. (See "Opening 

•

If these steps do not correct the problem, 

contact a service representative.

If white spots appear on the page:

•

The paper is too rough and a lot of dirt from a 

paper falls to the inner devices within the 

machine, so the transfer roller may be dirty. 

Clean the inside of your machine. (See 

•

The paper path may need cleaning. (See 

If black vertical streaks appear on the page:

•

The surface (drum part) of the toner 

cartridge inside the machine has probably 

been scratched. Remove the toner cartridge 

and install a new one. (See "Replacing the 

If white vertical streaks appear on the page:

•

The surface of the LSU part inside the 

machine may be dirty. (See "Cleaning the 

If the amount of background shading becomes 

unacceptable:

•

Change to a lighter weight paper. (See "Print 

•

Check the environmental conditions: very 

dry conditions or a high level of humidity 

(higher than 80% RH) can increase the 

amount of background shading.

•

Remove the old toner cartridge and, install a 

new one. (See "Replacing the toner 

If toner smears on the page: 

•

Clean the inside of the machine. (See 

•

Check the paper type and quality. (See "Print 

•

Remove the toner cartridge and then, install 

a new one. (See "Replacing the toner 

If marks repeatedly appear on the printed side of 

the page at even intervals:

•

The toner cartridge may be damaged. If you 

still have the same problem, remove the 

toner cartridge and, install a new one. (See 

•

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.
