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.
The machine does not 
print PDF files 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 
enable the file to print. 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.  Re
duce 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.

Printing quality problems
If the inside of the machine is dirty or paper has been loaded  improperly, there might be a redu ction in print quality. See the table below to clear the problem. 
 
ConditionSuggested solutions
Light or faded print • If a vertical white streak or faded area appears on the page , the toner supply is low. Install a new toner cartridge (see "Rep lacing the 
toner cartridge" on page 81).
• If a vertical white streak or faded area still appears on the page even though the machine has enough toner supply, open and c lose 
the front door 3 ~ 4 times (see "Machine overview" on page 19).
• The paper may not meet paper specifications; fo r example, the paper may be too moist or rough.
• If the entire page is light, the print resolution setting is t oo low or the toner save mode is on. Adjust the print resolution  and turn 
the toner save mode off. See the help screen of the printer driver.
• A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning. Clean the inside of your machine  (see "Cleaning the machine" on page 89).
• The surface of the LSU part inside the ma chine may be dirty. Clean the inside of your machine (see "Cleaning the machine" on p age 
89). If these steps do not correct the problem, contact a service representative.
The top half of the paper is 
printed lighter than the rest of 
the paper The toner might not adhere properly to this type of paper.
• Change the printer option and try again. Go to 
Printing Preferences, click the Paper tab, and set the paper type to Recycled  (see 
"Opening printing preferences" on page 54).

Toner specks• The paper may not meet specifications; for ex ample, the paper may be too moist or rough.
• The transfer roller may be dirty. Cl ean the inside of your machine (see "Cleaning the machine" on page 89).
• The paper path may need cleaning.  Contact a service representative (see "Cleaning the machine" on page 89).
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 ha s moist spots on its surface. Try a different brand of paper.
• The paper lot is bad. The manufacturing pr ocesses can cause some areas to reject toner. Try a different kind or brand of paper .
• Change the printer option and try again. Go to  Printing Preferences, click the Paper tab, and set type to  Thick (see "Opening 
printing preferences" on page 54).
If these steps do not correct the problem, contact a service representative.
White Spots  If white spots appear on the page:
• The paper is too rough and a lot of dirt from paper falls to th e inner components within the machine, so the transfer roller m ay be 
dirty. Clean the inside of your machine  (see "Cleaning the machine" on page 89).
• The paper path may need cleaning. Clean the inside of  your machine (see "Cleaning the machine" on page 89).
If these steps do not correct the problem, contact a service representative.

Vertical linesIf 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 instal l 
a new one (see "Replacing the imaging unit" on page 85).
If white vertical streaks appear on the page:
• The surface of the LSU part inside the ma chine may be dirty. Clean the inside of your machine (see "Cleaning the machine" on p age 
89). If these steps do not correct the problem, contact a service representative.
Black or color background If the amount of background shading becomes unacceptable:
• Change to a lighter weight paper.
• Check the environmental conditions: very dry conditions or a hi gh level of humidity (higher than 80% RH) can increase the amou nt 
of background shading.
• Remove the old imaging unit and install a new on e (see "Replacing the imaging unit" on page 85).
• Thoroughly redistribute the toner (see "Redistributing toner" on page 79).
Toner smear • Clean the inside of the machine (see "Cleaning the machine" on page 89).
• Check the paper type and quality.
• Remove the imaging unit and install a new one  (see "Replacing the imaging unit" on page 85).

Vertical repetitive defectsIf marks repeatedly appear on the printe d side of the page at even intervals:
• The imaging unit may be damaged. If you still have the same  problem, remove the imaging unit and, install a new one (see 
"Replacing the imaging unit" on page 85).
• Parts of the machine may have toner on them. If the defects oc cur 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.
Background scatter Background scatter results from bits of tone r 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 covers the entire surface area of a prin t
 ed page, adjust the print resolution through your software application 
or in Printing Preferences  (see "Opening printing preferences" on page 54). En sure the correct paper type is selected. For example: 
If Thicker Paper is selected, but Plain Paper actually used,  an overcharging can occur causing this copy quality problem.
• If you are using a new toner cartridge, redistribute the toner first (see "Redistributing toner" on page 79).
 
 
Toner particles are around bold 
characters or pictures The toner might not adhere properly to this type of paper.
• Change the printer option and try again. Go to 
Printing Preferences, click the Paper tab, and set the paper type to Recycled  (see 
"Opening printing preferences" on page 54).
• Ensure the correct paper type is selected. For example: If Thic ker Paper is selected, but Plain Paper actually used, an overcharging 
can occur causing this copy quality problem.

If the problem persists, the machine may requ ire repair. Contact a service representative.
Character voids Character voids are white areas within parts of characters that should be solid black:
• You may be printing on the wrong surface of th e paper. Remove the paper and turn it around. 
• The paper may not meet paper specifications.

occurs Your machine is probably being used at an
 altitude of 1,000 m (3,281 ft) or above.
The high altitude may affect the print quality, such as loose to ner or light imaging. Change the altitude setting for your mach ine (see 
"Altitude adjustment" on page 224).
