Printing quality problems

If the inside of the machine is dirty or paper has been loaded improperly, you may notice a reduction in print quality. See the table below to clear the problem.

Condition

Suggested solutions

 

 

Light or faded

If a vertical white streak or faded area appears on

print

the page:

AaBbCc

• The toner supply is low. You may be able to

temporarily extend the toner cartridge life. See

AaBbCc

page 8.3. If this does not improve the print

AaBbCc

quality, install a new toner cartridge.

• The paper may not meet paper specifications; for

AaBbCc

example, the paper is too moist or too rough. See

AaBbCc

page 3.2.

 

• 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 Software Section and

 

page 2.6, respectively.

•A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning. See page 8.2.

•The surface of the LSU part inside the machine may be dirty. Clean the LSU. See page 8.2.

Toner specks

• The paper may not meet specifications; for

AaBbCc

example, the paper is too moist or too rough. See

Dropouts

If faded areas, generally rounded, occur randomly

 

on the page:

AaBbCc

• A single sheet of paper may be defective. Try

AaBbCc

reprinting the job.

• The moisture content of the paper is uneven or

AaBbCc

the paper has moist spots on its surface. Try a

AaBbCc

different brand of paper. See page 3.2.

AaBbCc

• The paper lot is bad. The manufacturing

 

processes can cause some areas to reject toner.

 

Try a different kind or brand of paper.

•If these steps do not correct the problem, contact a service representative.

Suggested solutions

may be dirty. Clean the LSU (see page 8.2).

 

Gray background

If the amount of background shading becomes

 

 

 

unacceptable:

 

 

 

AaBbCc

• Change to a lighter weight paper. See page 3.2.

AaBbCc

• Check the machine’s environment: very dry (low

AaBbCc

humidity) or high humidity (higher than 80% RH)

conditions can increase the amount of background

AaBbCc

shading.

AaBbCc

• Remove the old toner cartridge and install a new

 

one. See page 8.4.

Toner smear

• Clean the inside of the machine. See page 8.1.

 

• Check the paper type and quality. See page 3.2.

 

• Remove the toner cartridge and install a new one.

 

See page 8.4.

Vertical repetitive If marks repeatedly appear on the printed side of

defects

the page at even intervals:

AaBbCc

• The toner cartridge may be damaged. If a

repetitive mark occurs on the page, print a

AaBbCc

cleaning sheet several times to clean the toner

AaBbCc

cartridge; see page 8.2. After the printout, if you

still have the same problems, remove the toner

AaBbCc

cartridge and install a new one. See page 8.4.

AaBbCc

• 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. Contact a service representative.

•If you use inferior quality paper; see page 8.2.
