Troubleshooting

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.

The machine
selects print
materials from
the wrong paper
source.

The paper source

selection in the

printer properties

may be incorrect.

For many software

applications, the paper

source selection is found

under the Thin Paper tab

within the printer properties.

Select the correct paper

source. See the printer driver

help screen.

A print job is
extremely slow.

The job may be very

complex.

Reduce the complexity of the

page or try adjusting the print

quality settings.

Half the page is
blank.

The page orientation

setting may be

incorrect.

Change the page orientation

in your application. See the

printer driver help screen.

The paper size and

the paper size

settings do not

match.

Ensure that the paper size in

the printer driver settings

matches the paper in the

tray.

Or, ensure that the paper

size in the printer driver

settings matches the paper

selection in the software

application settings you use.

The machine
prints, but the
text is wrong,
garbled, or
incomplete.

The printer cable is

loose or defective.

Disconnect the printer cable

and reconnect. Try a print job

that you have already printed

successfully. If possible,

attach the cable and the

machine to another computer

and try a print job that you

know works. Finally, try a

new printer cable.

The wrong printer

driver was selected.

Check the application’s

printer selection menu to

ensure that your machine is

selected.

The software

application is

malfunctioning.

Try printing a job from

another application.

The operating

system is

malfunctioning.

Exit Windows and reboot the

computer. Turn the machine

off and then back on again.

Pages print, but
are blank.

The toner cartridge

is defective or out of

toner.

Redistribute the toner, if

necessary. (See

"Redistributing toner" on

page 67.)

If necessary, replace the

toner cartridge.

The file may have

blank pages.

Check the file to ensure that

it does not contain blank

pages.

Some parts, such as

the controller or the

board, may be

defective.

Contact a service

representative.

CONDITION

POSSIBLE

CAUSE

SUGGESTED SOLUTIONS

The printer does
not print PDF file
correctly. Some
parts of
graphics, text, or
illustrations are
missing.

Incompatibility

between the PDF

file and the Acrobat

products.

Printing the PDF file as an

image may solve this

problem. Turn on Print As
Image

from the Acrobat

printing options.

It will take longer to

print when you print a

PDF file as an image.

The print quality
of photos is not
good. Images
are not clear.

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.

Before printing,
the machine
emits vapor near
the output tray.

Using damp paper

can cause vapor

during printing.

This is not a problem. Just

keep printing.

CONDITION

SUGGESTED SOLUTIONS

Light or faded print

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 "Replacing the toner cartridge" on

page 68.) If this does not improve the print

quality, install a new toner cartridge.

The paper may not meet paper

specifications; for example, the paper is too

moist or too rough. (See "Selecting print

media" on page 38.)

If the entire page is light, the print

resolution setting is too low. Adjust the print

resolution. See the help screen of the

printer driver.

A combination of faded or smeared defects

may indicate that the toner cartridge needs

cleaning.

The surface of the LSU part inside the

machine may be dirty. Clean the LSU,

contact a service representative.

Toner specks

The paper may not meet specifications; for

example, the paper is too moist or too

rough. (See "Selecting print media" on

page 38.)

The paper path may need cleaning. (See

"Cleaning the inside" on page 64.)
