Windows how to send graphic images to the printer. All
graphics can be printed as raster images, however some
geometric shapes or patterns print faster if they are printed as
vector graphics.
• Vector – If you select the Vector setting, Windows will send
graphics to the printer as a mixture of vector and
bitmap images.
• Raster – When you select the Raster setting, Windows will
send all graphics to the printer as bit map images.
Note: Not all graphic images can print using the Vector
setting. If you are using the Vector setting, and your graphic
images do not print as they appear on your computer screen,
select the Raster setting and reprint your graphic.
Halftoning
This option can be used for configuring the halftone of the

• Device – Choose this setting for printed graphic image that
printer provides.
• Fine – Choose this setting for printed images that you want
to have a smooth, realistic and photographic
appearance. This setting provides soft contrasts
between various shades of gray. This setting also
works well for images originally designed with color.
• Coarse – Choose this setting if your graphic images were
originally scanned in through a scanner.
• Line art – Choose this setting for graphic images with
intricate lines and fine detail, like clip art graphics.
This setting provides solid lines and sharp
contrasts between shaded areas.

Using Page Overlay
What is an Overlay?
Dear ABC
Regards
An overlay is text and/or images stored in the computer HDD
as a special file format that can be printed on any document
you choose. Overlays are often used to take the place of
preprinted forms and letterhead paper. Rather than using
preprinted letterhead, for example, you can create an overlay
containing the exact same information that is currently on
your letterhead. Then when you want to print a letter with
your company’s letterhead, you do not need to load preprinted
letterhead paper in the printer. You need only to tell the
printer to print the letterhead overlay on your document.

6 Maintaining⇤
Maintaining
Your Printer
This chapter provides suggestions for high-quality and
economical printing and information for maintaining the toner
cartridge and the printer.
Topics included in this chapter are:
◆ Maintaining Toner Cartridge
◆ Cleaning the Printer
6.2 MAINTAINING YOUR PRINTER
Maintaining Toner Cartridge
Toner cartridge
storage
To get the most from the toner cartridge, keep the following
guidelines in your mind.
• Do not remove the toner cartridge from its package until you
are ready to use it. The shelf life of a cartridge in an unopened
package is approximately 2 years. The shelf life of a cartridge
in an opened package is approximately 6 months.
• Do not refill toner cartridges. The printer warranty does not
cover damage caused by using a refilled cartridge.
• Store toner cartridges in the same environment as the printer.
• Do not remove a toner cartridge from the printer except to
replace it, clean it or clear a paper jam. Replace the cartridge
immediately.
• To prevent damage to the toner cartridge, do not expose it to
light for more than a few minutes.
Toner cartridge life
expectancy
The life of the toner cartridge depends on the amount of toner
that print jobs require. When printing text at 5 % coverage, a
new toner cartridge lasts an average of 8,000 pages. (But, the
toner cartridge supplied with the printer lasts an average of
4,000 pages.)
Recycling toner
cartridge
After you install a new toner cartridge (see page 2.2), follow the
instructions included in the toner cartridge box to recycle the old
cartridge.
Saving toner
To save toner, press the Toner Save button on the printer
control panel. The button will be lit. You can also enable the
Toner Save Mode in your printer properties. Refer to “Using
Toner Save Mode” on page 5.6. Selecting this option will expand
the life of the toner cartridge and reduce your cost per page, but
will reduce print quality.
MAINTAINING YOUR PRINTER 6.1
Toner Cartridge
Redistributing Toner
When toner is low, faded or light areas may appear on a printed page. You may be able to
temporarily improve print quality by redistributing the toner. The following procedures may
allow you to finish the current print job before replacing the toner cartridge.
Open the top cover.
Remove the toner cartridge from the
printer.
CAUTIONS:
• Avoid reaching too far into the
printer. The fusing area may be hot.
• To prevent damage to the toner
cartridge, do not expose it to light
for more than a few minutes.
Gently shake the toner cartridge from
side to side 5 or 6 times to redistribute
the toner.
Note: If the toner gets on your
clothing, wipe it off with a dry cloth
and wash clothing in cold water. Hot
water sets toner into fabric.
6.2 MAINTAINING YOUR PRINTER
Toner Cartridge
Reinsert the toner cartridge into the
printer. Be sure that the toner cartridge
is firmly in its place.
Firmly close the cover.
If the print remains light
Remove the old cartridge and install a
new toner cartridge. See “Install the
Toner Cartridge” on page 2.2.
MAINTAINING YOUR PRINTER 6.3
Cleaning the Printer
To maintain print quality, follow the cleaning procedures below every time the toner cartridge
is replaced or whenever print quality problems occur. As much as possible, keep the printer
free from dust and debris.
Notes:
• Do not use ammonia-based cleaners or volatile solvents such as thinner, on or around the
printer. These can damage the printer.
• While cleaning the inside of the printer, be careful not to touch the transfer roller (located
underneath the toner cartridge ). The oil from your hands on the roller can cause print
quality problems.
Cleaning the Outside
Wipe the outside surface of the printer with a soft, clean, lintfree cloth. You can dampen the cloth slightly with water, but be
careful not to be let any water drip onto the printer or inside of
it.
Cleaning the Inside
During the printing process, paper, toner, and dust particles
can accumulate inside the printer. Over time, this buildup can
cause print quality problems such as toner specks or smearing.
Cleaning inside the printer will eliminate or reduce these
problems.
Cleaning inside the 1
printer
Turn the printer off and unplug the power cord, then wait for
the printer to cool.
2 Open the top cover and remove the toner cartridge.
Note: To prevent damage
to the toner cartridge, do
not expose it to light for
more than a few minutes.
Cover it with a piece of
paper, if necessary. Also,
do not touch the black
transfer roller inside the
printer. By doing so, you
can damage the printer.
6.4 MAINTAINING YOUR PRINTER
3 With a dry, lint-free cloth, wipe away any dust and spilled toner
from the toner cartridge area and the toner cartridge cavity.
Cleaning the Printer
4 Locate the long strip of glass (LSU) inside the top of the
cartridge compartment, and gently swab the glass to see if dirt
turns the white cottom black.
5 Reinsert the toner cartridge and close the top cover. Then, turn
the printer on.
Printing a cleaning
sheet
Printing a cleaning sheet cleans the drum inside the toner
cartridge. Use this process if you are experiencing blurred,
faded or smeared printouts. This process will produce a page
with toner debris, which should be discarded.
1 Make sure the printer is turned on and in the ready state and
that there is paper loaded in the paper tray.
2 Press and hold Demo on the control panel for about 10 seconds
until all control panel lights remain steadily lit, then release.

7.6 PROBLEM SOLVING
Clearing Paper Jams
Occasionally, paper can become jammed during a print job. Some of the causes include:
• The paper tray is loaded improperly or overfilled.
• The paper tray has been pulled out during a print job.
• The top cover has been opened during a print job.
• Paper that does not meet paper specifications has been used. See “Paper Specifications” on
page A.2.
• Paper that is outside of the supported size range has been used. See “Paper Specifications”
on page A.2.
If a paper jam occurs, the Paper and the Error lights remain lit on the control panel. Find
and remove the jammed paper. If the location of the paper jam is not obvious, look inside the
printer.
Output Area
Note: Paper jams in this area may result in loose toner on the page. If you get any toner on
your clothes, wash them in cold water because hot water will set the toner into the fabric.
If the paper is almost completely visible
from the top output tray, pull the
remaining paper carefully out of the
printer.
PROBLEM SOLVING 7.7
Clearing Paper Jams
If the jammed paper is not visible or
there is resistance when you pull the
paper, open the rear output tray.
Remove the stopper fastening the rear
output tray, and push the tray down so
that it is open at 90 degrees angle.
If there is resistance when you pull the
paper, squeeze the handle on the right
end of the exit roller 1 , then pull the
roller in the direction of arrow 2 .

paper.
Remove any misfed paper by pulling it
out by the visible edge from the tray.
Make sure that all of the paper is
properly aligned in the tray.
Note: If the paper is jammed in the
paper feed area and cannot be
accessed from inside the printer,
