Troubleshooting_ 111

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. 

The resolution of 

the photo is very 

low. 

Reduce the photo size. If 

you increase the photo size 

in the software application, 

the resolution will be 

reduced. 

Using damp paper 

can cause vapor 

during printing.

This is not a problem. Just 

keep printing.

Paper size and 

paper size setting 

do not match.

Set the correct paper size in 

the Custom in the Paper tab 

in the Printing Preferences. 

(See "Paper tab" on 

•

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 101.) If this does not improve the 

print quality, install a new toner cartridge.

•

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 

inside" on page 99.)

•

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.

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 

"Cleaning the inside" on page 99.).

•

The paper path may need cleaning. (See 

"Cleaning the inside" on page 99.)

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

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
