<Troubleshooting>

If the inside of the machine is dirty or paper has been loaded improperly, 
you may notice a reduction in print quality. See the table below to clear 
the problem. 

If a vertical white streak or faded area appears 
on the page:

• The toner supply is not enough. 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 color tone might not be adjusted. Adjust 

the color tone. (Page 10.8) 

• The paper may not meet paper 

specifications; for example, the paper may 
be too moist or rough. (Page 4.3)

• 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. See the help screen of 
the printer driver and refer to Software 
section, respectively.

• A combination of faded or smeared defects 

may indicate that the toner cartridge needs 
cleaning. Contact a service representative.

• The surface of the LSU part inside the 

machine may be dirty. Clean the LSU, 
contact a service representative. 

• The paper may not meet specifications; for 

example, the paper may be too moist or 
rough. (Page 4.3)

• The transfer roller may be dirty. Clean the 

inside of your machine. Contact a service 
representative.

• The paper path may need cleaning. Contact 

a service representative.

• Check the location of the machine. If the 

area is not well-ventilated, this problem may 
occur. (Page 3.1)

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. (Page 4.3)

• The paper lot is bad. The manufacturing 

processes can cause some areas to reject 
toner. Try a different kind or brand of paper.

• If these steps do not correct the problem, 

contact a service representative.

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. 
(Page 11.2) Contact a service 
representative.

• The paper path may need cleaning. Contact 

a service representative.

If black vertical streaks appear on the page:

• The drum inside the printer has probably 

been scratched. Remove the imaging unit 
and install a new one. (Page 11.6)

If white vertical streaks appear on the page:

• The surface of the LSU part inside the 

machine may be dirty. Clean the LSU. 
Contact a service representative.

• The inside of the Imaging Unit  may be dirty. 

Change the Imaging Unit. 

If vertical streaks appear on the page:

• The surface of the scanner glass and its 

white sheet may be dirty. Clean these unit. 
See 11.2 . If this problem persists, contact a 
service representative.

If the amount of background shading becomes 
unacceptable:

• Change the IBT if it has reached its lifespan.
• Check the environmental conditions: very 

dry conditions (low humidity) or a high level 
of humidity (higher than 80% RH) can 
increase the amount of background 
shading.

• Remove the old imaging unit and then, 

install a new one. (Page 11.4)

• Clean the inside of the machine. Contact a 

service representative.

• Check the paper type and quality. 

(Page 4.3)

• Remove the imaging unit and then, install a 

new one. (Page 11.4)

• Change the IBT if it has reached its lifespan.
