Replacing the toner cartridge
When the toner is completely empty or the toner cartridge reachde the 
end of its life  span:
• The Smart Panel program window appears on the computer.
•The  Error LED blinks red.
At this stage, the toner cartridge needs to be replaced. For toner 
cartridge ordering information, see page 7.1.
1 Open the front cover.
2 Pull the old toner cartridge out.
3 Remove the new toner cartridge from its bag.
4 Thoroughly shake the cartridge 5 or 6 times to distribute the toner 
evenly inside the cartridge.
Thoroughly shake the cartridge to assure maximum copies per 
cartridge.
Caution
• Do not use sharp objects, such as a knife or scissors, to open 
the toner cartridge package. They might scratch the drum of 
the cartridge.
5 Remove the paper protecting the toner cartridge by pulling the 
packing tape.
6 Hold the toner cartridge by the handle and slowly insert the 
cartridge into the opening in the printer.
Tabs on the sides of the cartridge and corresponding grooves 
within the printer will guide the cartridge into the correct position 
until it locks into place completely.
7 Close the front cover. Make sure that the cover is securely closed.
Note
• Refer to the helpful pictures on the cartridge wrapping paper.
Caution
• If toner gets on your clothing, wipe it off with a dry cloth and 
wash clothing in cold water. Hot water sets toner into fabric.
• 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. 
• Do not touch the green surface underside of the toner  cartridge. Use the handle on the cartridge to avoid touching 
this area.

This chapter provides helpful information for what to do if you encounter 
an error while using your printer. 
This chapter includes:
• Clearing paper jams
• Troubleshooting checklist
• Understanding the LEDs
• Solving general printing problems
• Solving print quality problems
• Common Windows problems

Clearing paper jams
When a paper jam occurs, the  Error LED lights red. Open and close the 
front cover. The jammed paper automatically exits the printer. 
In the paper feed area
In the standard tray
1 Remove the jammed paper by gently pulling it straight out. Make 
sure that all of the paper is properly aligned in the standard tray.
If the paper does not move when you pull, or if you do not see the 
paper in this area, check the fuser area around the toner cartridge. 
See page 9.2.
2 Open and close the front cover to resume printing the document 
from failed pages.
Note
• When removing paper that is jammed in the printer, if possible 
always pull the paper in the direction that it normally moves so 
as not to damage internal components. Always pull firmly and 
evenly; do not jerk the paper. If the paper tears, ensure that all 
fragments of paper are removed; otherwise a jam will occur 
again.

Solving print quality problems
Dirt inside of the printer or improper paper loading may reduce print 
quality. See the table below to troubleshoot problems. 
ConditionSuggested 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 
page 8.3. If this does not improve 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 page 5.3.
• 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 the 
Software Section .
• A combination of faded or smeared defects 
may indicate that the printer needs cleaning. 
See page 8.1.
• The surface of LSU may be dirty. Clean the 
LSU. See page 8.2.
Toner spots • The paper may not meet specifications (for 
example, the paper is too moist or too rough). 
See page 5.3.
• The transfer roller or paper path may be dirty. 
See page 8.1.
Dropouts If generally rounded, faded areas 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 page 5.3.
• The paper lot is bad. The manufacturing 
processes can cause some areas to reject 
toner. Try a different kind or brand of paper.
• The toner cartridge may be defective. See 
“Vertical repetitive defects” on the next 
column.
• If these steps do not correct the problems, 
contact a service representative.
Vertical lines If black vertical streaks appear on the page:
• The drum inside the toner cartridge has 
probably been scratched. Install a new toner 
cartridge. See page 8.4.
If white vertical streaks appear on the page:
• The surface of the LSU part inside the printer  may be dirty. Clean the LSU. See page 8.2.
Gray 
background If the amount of background shading becomes 
unacceptable, the procedures below may fix the 
problem.
• Change to lighter weight pages. See page 5.3.
• Check the printer’s environment; low humidity 
(lower than 20% RH) 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 page 8.4.
Toner smear • Clean the inside of the printer. See page 8.1.
• Check the paper type and quality. See page 
5.2.
• Remove the toner cartridge and install a new  one. See page 8.4.
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, install a 
new toner cartridge. See page 8.4.
• 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.
• The fusing assembly may be damaged.  Contact a service representative.
ConditionSuggested solutions

9.8   
Background 
scatter 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 
via the printer properties window.
Misformed 
characters • If characters are improperly formed and 
producing hollowed images, the paper stock 
may be too slick. Try a different paper. See 
page 5.3.
Page skew • Ensure that the paper is loaded properly.
• Check the paper type and quality. See page 
5.2.
• Ensure that the paper is loaded correctly and  the adjustable guides are not too tight or too 
loose against the paper stack.
Curl or wave • Ensure that the paper is loaded properly.
• Check the paper type and quality. Both high 
temperature and humidity can cause paper 
curl. See page 5.2.
• Turn over the stack of paper in the tray. Also 
try rotating the paper 180° in the tray.
ConditionSuggested solutions
Wrinkles or 
creases • Ensure that the paper is loaded properly.
• Check the paper type and quality. See page 
5.2.
• Turn over the stack of paper in the tray. Also  try rotating the paper 180° in the tray.
Back of 
printouts are 
dirty • The transfer roller may be dirty. See page 8.1.
• Check for leaking toner. Clean the inside of 
the printer. 
Solid black 
pages • The toner cartridge may not be installed 
properly. Remove the cartridge and reinsert.
• The toner cartridge may be defective and 
need replacing. Install a new toner cartridge.
• The printer may require repair. Contact a  service representative.
Loose toner • Clean the inside of the printer. 
• Check the paper type and quality. See page 
5.2.
• Install a new toner cartridge. See page 8.4.
• If the problem persists, the printer may require  repair. Contact a service representative.
Character voids Character voids are white areas within 
characters that should be solid black:
• If you are using transparencies, try another 
type of transparency. Because of the 
composition of the transparency, some 
character voids may be normal. 
• You may be printing on the wrong surface on 
the paper. Turn over the paper in the tray. 
• The paper may not meet paper specifications.  See page 5.3.
