type, size, and weight.
• If multiple sheets have caused a paper jam, clear the paper jam.
Paper does not feed into
the machine.
• Remove any obstructions from inside the machine.
• Paper has not been loaded correctly. Remove paper from the tray and
reload it correctly.
• There is too much paper in the tray. Remove excess paper from the tray.
• The paper is too thick. Use only paper that meets the specifications
required by the machine.
• If an original does not feed into the machine, the DADF rubber pad may
require to be replaced. .
The paper keeps jamming.
• There is too much paper in the tray. Remove excess paper from the tray. If
you are printing on special materials, use the multi-purpose tray.
• An incorrect type of paper is being used. Use only paper that meets the
specifications required by the machine.
• There may be debris inside the machine. Open the front cover and remove
the debris.
• If an original does not feed into the machine, the DADF rubber pad may
require to be replaced.
Transparencies stick
together in the paper exit.

If you are under the DOS
environment, the font setting
for your machine may be set
incorrectly.
Suggested solutions: Change the language
setting.
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.

4.2.2.3 Printing quality problems
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. 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.
• 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.
• 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.
Toner specks
• The paper may not meet specifications; for example, the paper is too moist or too
rough.
• The transfer roller may be dirty. Clean the inside of your machine.
• The paper path may need cleaning.
Dropouts
If faded areas, generally rounded, 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.
• The paper lot is bad. The manufacturing processes can cause some areas to
reject toner. Try a different kind or brand of paper.
Vertical lines
If black vertical streaks appear on the page:
• The surface(drum part) of the imaging unit inside the machine has probably been
scratched. Remove the imaging unit and install a new one.
If white vertical streaks appear on the page:
• The surface of the LSU part inside the machine may be dirty. Clean the LSU.
Gray background
If the amount of background shading becomes unacceptable:
• Change to a lighter weight paper.
• Check the machine’s environment: very dry (low humidity) or high humidity (higher
than 80% RH) conditions can increase the amount of background shading.
• Remove the old drum and toner cartridge and then, install a new one.

Condition
Toner smear
Suggested solutions
• Clean the inside of the machine.
• Check the paper type and quality.
• Remove the drum and toner cartridge and then, install a new one.
Vertical repetitive
defects
If marks repeatedly appear on the printed side of the page at even intervals:
• The imaging unit may be damaged. If a repetitive mark occurs on the page, run a
cleaning sheet through several times to clean the cartridge; After the printout, if
you still have the same problems, remove the imaging unit and then, install a new
one.
• 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.
Background scatter
Background scatter results from bits of toner randomly 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.
Misformed
characters
• If characters are improperly formed and producing hollow images, the paper stock
may be too slick. Try a different paper.
• If characters are improperly formed and producing a wavy effect, the scanner unit
may need service.
Page skew
• Ensure that the paper is loaded properly.
• Check the paper type and quality.
• Ensure that the paper or other material is loaded correctly and the guides are not
too tight or too loose against the paper stack.

Condition
Suggested solutions
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.
• Turn the stack of paper over in the tray. Also try rotating the paper 180° in the
tray.
Wrinkles or creases
Back of printouts
are dirty
• Ensure that the paper is loaded properly.
• Check the paper type and quality.
• Turn over the stack of paper in the tray. Also try rotating the paper 180° in the
tray.
Check for leaking toner. Clean the inside of the machine.
Black pages
• The imaging unit may not be installed properly. Remove the cartridge and reinsert
it.
• The imaging unit may be defective and need replacing. Remove the drum
cartridge and install a new one.
• The machine may require repair.
Loose toner
• Clean the inside of the machine.
• Check the paper type and quality.
• Remove the imaging unit and then, install a new one.
• If the problem persists, the machine may require repair.

Condition
Suggested solutions
Character Voids
Character voids are white areas within parts of characters that should be solid
black:
• If you are using transparencies, try another type of transparency. Because of the
composition of transparencies, some character voids are normal.
• You may be printing on the wrong surface of the paper. Remove the paper and
turn it around.
• The paper may not meet paper specifications.
Horizontal stripes
If horizontally aligned black streaks or smears appear:
• The imaging unit may be installed improperly. Remove the cartridge and reinsert
it.
• The imaging unit may be defective. Remove the toner cartridge and install a new
one.
• If the problem persists, the machine may require repair.
Curl
If the printed paper is curled or paper does not feed into the machine:
• Turn over the stack of paper in the tray. Also try rotating the paper 180° in the
tray.
White Spots
White spots appears on the page:
• The paper is too rough and a lot of dirt from a paper falls to the inner devices
within the machine, so the transfer roller may be dirty. Clean the inside of your
machine.
• The paper path may need cleaning.
An unknown image
repetitively appears
on a next few sheets
or loose toner, light

Service Manual
You printer is probably being used at an altitude of 2,500 m(8,200 ft)or above. The
