sheet-by-sheet in the Tray, send print data to print the first
page, and press the On-Line/Continue button ( ) on the
control panel to print each following page.
1 Load a sheet of print material on the centre of the
Multi-Purpose Tray with the print side up.
2 Slide the paper width guide and adjust it against the
material without bending.

Printing on Envelopes
Guidelines
• Only use envelopes recommended for laser printers. Before
loading envelopes in the Multi-Purpose Tray, make sure that
they are undamaged and are not stuck together.
• Do not feed stamped envelopes.
• Never use envelopes with clasps, snaps, windows, coated
lining, or self-stick adhesives. These envelopes may severely
damage the printer.
1 Open the Multi-Purpose Tray and slide the extender to its
full-length position.
2 Open the rear output tray and pull the extender.
4.14 USING PRINT MATERIALS
3 Flex or fan the edge of the envelope stack to separate the

flap side down.
The stamp area is on the left side and the end of the
envelope with the stamp area enters the tray first.
5 Adjust the guide to the edge of the envelope stack.
USING PRINT MATERIALS 4.15
6 When you print on envelopes, configure the paper source,
type and size properly in the software application. For
details, see page 5.7.
For details about setting on the control panel, see page 3.5.
7 After printing, close the Multi-Purpose Tray and the rear
output tray.
4.16 USING PRINT MATERIALS
Printing on Labels
Guidelines
• Only use labels recommended for laser printers.
• Verify that the labels’ adhesive material can tolerate fusing
temperature of 200°C (392°F) for 0.1 second.
• Make sure that there is no exposed adhesive material
between the labels. Exposed areas can cause labels to peel
off during printing, which can cause paper jams. Exposed
adhesive can also cause damage to printer components.
• Do not feed a sheet of label through the printer more than
once. The adhesive backing is designed for one pass through
the printer.
• Do not use labels that are separating from the backing sheet
or are wrinkled, bubbled, or otherwise damaged.
1 Open the Multi-Purpose Tray and the rear output tray.
2 Load labels with the print side up. Adjust the guide to fit
the width of the labels.
USING PRINT MATERIALS 4.17
3 When you print on labels, configure the paper source, type
and size properly in the software application. For details,
see page 5.7.
For details about setting on the control panel, see page 3.5.
4 After printing, close the Multi-Purpose Tray and the rear
output tray.
NOTE: To prevent labels from sticking, do not let the printed label
sheets stack up as they are printed out.
4.18 USING PRINT MATERIALS
Printing on Transparencies
Guidelines
• Only use transparencies recommended for use in laser
printers.
• Ensure that transparencies are not wrinkled, curled, or have
any torn edges.
• Hold the transparencies by the edges and avoid touching the
print side. Oils deposited on the transparency can cause print
quality problems.
• Be careful not to scratch or leave fingerprints on the print
side.
1 Open the Multi-Purpose Tray and the rear output tray.
2 Load transparencies with the print side up, and the top
with the adhesive strip entering the printer first.
Adjust the guide to fit the width of the transparencies.
USING PRINT MATERIALS 4.19
3 When you print on transparencies, configure the paper
source, type and size properly in the software application.
For details, see page 5.7.
For details about setting on the control panel, see page 3.5.
4 After printing, close the Multi-Purpose Tray and the rear
output tray.
NOTES:
• If you print on thin transparencies to the rear output tray, they
can be curled. In this case, use the top output tray. If the
problem persists, check if your transparencies meets the
printer’s specifications.
• To prevent transparencies from sticking, do not let the printed
sheets stack up as they are printed out.
• Place transparencies on a flat surface after removing them from
the printer.
4.20 USING PRINT MATERIALS
Printing on Preprinted Paper
Preprinted paper is paper that has some type of printing placed
on it before it is sent through the printer (paper that has a
preprinted logo at the top of the page, for example).
Guidelines
• Letterheads must be printed with heat-resistant ink that will
not melt, vaporize, or release hazardous emissions when
subjected to the printer’s fusing temperature of 400 °F
(205 °C) for 0.1 second.
• Ink on letterheads must be non-flammable and should not
adversely affect any printer rollers.
• Forms and letterheads should be sealed in a moisture-proof
wrapping to prevent changes during storage.
• Before you load preprinted paper as forms and letterheads,
verify that the ink on the paper is dry. During the fusing
process, wet ink can come off preprinted paper.
1 Load letterheads into the tray you want to use, as shown in
the figures below. Adjust the guides to fit the width of the
paper stack.
Load with the design face
down, bottom edge
towards the printer.
Load with the design face
up, top edge towards the
printer.
USING PRINT MATERIALS 4.21
2 When you print, configure the paper source, type and size
properly in the software application. For details, see
page 5.7.
For details about setting on the control panel, see page 3.5.
Printing on Card Stock or
Custom-sized Materials
Postcards, 3.5 by 5.83 in. (index) cards and other custom-sized
materials can be printed with your printer. The minimum size is
76 by 127 mm (3 by 5 in.) and the maximum size is 216 by
356 mm (8.5 by 14 in.).
Guidelines
• Always insert the short-edge into the Multi-Purpose Tray first.
If you want to print in landscape mode, make this selection
through your software. Inserting paper long-edge first may
cause a paper jam.
• Do not load more than 10 cards into the Multi-Purpose Tray at
a time.
• Do not print on media smaller than 76 mm (3 in.) wide or
127 mm(5 in.) long.
• Set margins at least 6.4 mm (0.25 in.) away from the edges
of the material in the software application
4.22 USING PRINT MATERIALS
1 Open the Multi-Purpose Tray and the rear output tray.
2 Load print material with print side up and short edge first.

Using Overlays
What is an Overlay?
Dear ABC
Regards
WORLD BEST
An overlay is text and/or images stored in the computer hard
disk drive (HDD) as a special file format that can be printed on
any document. Overlays are often used to take the place of
preprinted forms and letterhead paper. Rather than using
preprinted letterhead, you can create an overlay containing the
exact same information that is currently on your letterhead. To
print a letter with your company’s letterhead, you do not need
to load preprinted letterhead paper in the printer. You need only
tell the printer to print the letterhead overlay on your document.
Creating a New Page Overlay
To use a page overlay, you must create a new page overlay
containing your logo or image.
1 Create or open a document containing text or an image for
WORLD BEST
use in a new page overlay. Position the items exactly as you
wish them to appear when printed as an overlay. If needed,
save the file for later use.
2 When you change the print settings from your software
application, access the printer properties. See page 5.2.
3 Click the Extras tab, and click Edit button in the Overlay
section.

MAINTAINING YOUR PRINTER
Maintaining the Toner Cartridge
Toner cartridge storage
To get the maximum results from the toner cartridge, keep the
following guidelines in mind:
• Do not remove the toner cartridge from its package until
ready for use.
• Do not refill the toner cartridge. The printer warranty does
not cover damage caused by using a refilled cartridge.
• Store toner cartridges in the same environment as the
printer.
• To prevent damage to the toner cartridge, do not expose it to
light for more than a few minute.
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 10,000 pages. (The
original toner cartridge supplied with the printer lasts an
average of 5,000 pages.)
Saving toner
To save toner, press the Toner Save button on the printer
control panel. The button backlight will be lit. You can also
enable Toner Save mode in the printer properties or from the
control panel menu. Refer to “Using the Toner Save Mode” on
page 5.9 and “Using Control Panel Menus” on page 3.5.
Selecting this option will extend the life of the toner cartridge
and reduce your cost per page, but it will reduce the print
quality.

Cleaning the Printer
To maintain the print quality, follow the cleaning procedures
below each time the toner cartridge is replaced or if print quality
problems occur.
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). Oil
from your fingers can cause print quality problems.
CAUTIONS: Cleaning the cabinet of the printer with surfactants
containing large amounts of alcohol, solvent or other strong
substances can discolor or crack the cabinet .
Cleaning the Outside
Clean the cabinet of the printer with a soft, lint-free 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. This buildup can cause print
quality problems, such as toner specks or smearing. Cleaning
the inside of the printer will eliminate or reduce these problems.
Cleaning inside the printer
1 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.

Solving Print Quality Problems
The dirty inside of the printer or improper paper loading may
reduce the print quality. See the table below to troubleshoot the
problem.
Problem
Solution
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 “Redistributing Toner” on
page 6.4. 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 “Paper
Specifications” on page G.3.
• If the entire page is light, the print resolution setting is too
light or Toner Save Mode is on. Adjust the print resolution
and Toner Save Mode in the printer properties. See
page 5.25 and page 5.9 respectively.
• A combination of faded or smeared defects may indicate that
the toner cartridge needs cleaning. See “Cleaning the Inside”
on page 6.7.
• The surface of LSU may be dirty. Clean the LSU. See

7.16 SOLVING PROBLEMS
If black vertical streaks appear on the page:
• The drum inside the toner cartridge has probably been
scratched. Install a new toner cartridge.
If the amount of background shading becomes unacceptable,
the procedures below may fix the problem.
• Change to a lighter weight pages. See “Paper Specifications”
on page G.3.
• Check the printer’s environment; very dry (low humidity) or
high humidity (higher than 80% RH) conditions can increase
the amount of background shading.
• Remove the old toner cartridge and install a new one. See
“Installing the Toner Cartridge” on page 2.4.
• Clean the inside of the printer. See “Cleaning the Inside” on
page 6.7.
• Check the paper type and quality. See “Paper Specifications”

• Remove the toner cartridge and install a new one. See
“Installing the Toner Cartridge” on page 2.4.
Problem
Solution
Vertical repetitive
defects
If marks repeatedly appear on the printed side of the page at
even intervals:
• The toner cartridge may be damaged. If a repetitive mark
occurs on the page, print a cleaning sheet several times to
clean the cartridge; see page 6.9. After the printout, if you
still have the same problems, install a new toner cartridge.
See “Installing the Toner Cartridge” on page 2.4.
• Parts of the printer 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.

Background scatter results from bits of toner distributed on the
printed page.
• The paper may be too damp. Try printing with a different
batch of paper. Do not open packages of paper until
necessary so that the paper does not absorb too much
moisture.
• If background scatter occurs on an envelope, change the
printing layout to avoid printing over areas that have
overlapping seams on the reverse side. Printing on seams
can cause problems.
• If background scatter covers the entire surface area of a
printed page, adjust the print resolution through your
software application or the printer properties.
• If characters are improperly formed and producing hollow
images, the paper stock may be too slick. Try a different
paper. See “Paper Specifications” on page G.3.
• If characters are improperly formed and producing a wavy
effect, the scanner unit may need service. Verify that it also
occurs on a demo page (see page 2.14). For service, contact
a service representative.
• Check the paper type and quality. See “Paper Specifications”
on page G.3.
• Ensure that the paper or other material is loaded correctly
and the guides are not too tight or too loose against the
paper stack.
