REDISTRIBUTING TONER
When the toner cartridge is near the end of its life:
•Whi
te streaks or light printing occurs. 
•Pr
epare new cartridge  appears on the display.
• The
  Status LED blinks red. 
If this happens, you can temporarily improve print quality by redistributing 
the
  remaining toner in the cartridge. In some cases, white streaks or light 
printing will still occur even after you have redistributed the toner.
1. O
pen the front door.
2.Pul
l the toner cartridge out.
3.Thoroughly roll the cartridge five or six times to distribute the toner 
evenly inside the cartridge.
 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.
 
Do not touch the green underside of the toner cartridge. Use the 
handle on the cartridge to avoid touching this area. 
4. H
old the toner cartridge by the handle and slowly insert the cartridge into 
the opening in the machine.  Tabs on the sides of the cartridge and corresponding grooves within the 
m

achine will guide the cartridge into the correct position until it locks into 
place completely.
5. Close the front door. Ensure that the cover is securely closed. 
CLEARING ORIGINAL DOCUMENT JAMS
When an original jams while passing through the document feeder, a 
warning message appears on the display screen.
 
To avoid tearing the document, remove the jammed document slowly 
and gently.
 To prevent document jams, use the scanner glass for thick, thin, or 
mixed paper-type originals.

1.Remove any remaining pages from the document feeder.
2. O
pen the document feeder cover.
3.Gently remove the jammed paper from the document feeder.
 If you see no paper in this area, go to step 5.
4. C
lose the document feeder cover. Reload the pages you removed, if 
any, in the document feeder.
5.Open the scanner lid.
6. Sei
ze the misfeed paper, and remove the paper from the feed area by 
carefully pulling it to the right using both hands.
7.Close the scanner lid. Load the removed pages back into the document 
feeder.
TIPS FOR AVOIDING PAPER CURLS
1.Open the rear door.
2. Pu
ll down the pressure lever on each side.
 Keep the rear cover opened during printing. 
Only use when the printout has more than 20 mm curl. 
TIPS FOR AVOIDING PAPER JAMS
By selecting the correct media types, most paper jams can be avoided. 
When a paper jam occurs, refer to the next guidelines. 
•E
nsure that the adjustable guides are positioned correctly (See  Loading 
paper in the tray on page  47 ).
• D
o not overload the tray. Ensure that the paper level is below the paper 
capacity mark on the inside of the tray.
• Do
 not remove paper from the tray while your machine is printing.
•F
lex, fan, and straighten paper before loading. 
•D
o not use creased, damp, or highly curled paper.

Printing quality problems
If the inside of the machine is dirty or paper has been loaded improperly, 
there might be a reduction in print quality. See the table below to clear the 
problem. 
Pages print, but 
they are blank. The toner cartridge 
is defective or out of 
toner. Redistribute the toner, if 
necessary. 
If necessary, replace the 
toner cartridge.
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 file correctly. 
Some parts of 
graphics, text, or 
illustrations are 
missing.Incompatibility

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

Reduce the photo size. If 
you increase the photo size

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

quality, install a new toner cartridge.
• The
 paper may not meet paper specifications; 
for example, the paper may be too moist or 
rough (See  Print media specifications on 
page  111 ).
• If th
e 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.
