Cleaning your machine
To maintain print and scan quality, follow the cleaning procedures below 
each time the toner cartridge is replaced or if print and scan quality 
problems occur.
Caution
Cleaning the cabinet of the machine with cleaning materials 
containing large amounts of alcohol, solvent, or other strong 
substances can discolor or distort the cabinet.
Cleaning the outside
Clean the cabinet of the machine with a soft lint-free cloth. You can 
dampen the cloth slightly with water, but be careful not to let any water 
drip onto or into the machine.
Cleaning the inside
During the printing process, paper, toner, and dust particles can 
accumulate inside the machine. This buildup can cause print quality 
problems, such as toner specks or smearing. Cleaning the inside of the 
machine clears or reduces these problems.
1Turn the machine off and unplug the power cord. Wait for the 
machine to cool down.
2 Open the front cover and pull the toner cartridge out. Set it on a 
clean flat surface .

3Pull the manual tray out.
4 With a dry lint-free cloth, wipe away any dust and spilled toner from 
the toner cartridge area and the toner cartridge cavity.
Caution
While cleaning the inside of the machine, be careful not to touch 
the transfer roller, located underneath the toner cartridge. Oil 
from your fingers can cause print scan quality problems. 
Cautions
• 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.

5 Locate the long strip of glass (LSU) inside the top of the cartridge 
compartment, and gently swab the glass to see if dirt turns the white 
cotton black.
6 Push the manual tray back into the machine.
7 Reinsert the toner cartridge and close the front cover.
8 Plug in the power cord and turn the machine on.
Cleaning the scan unit
Keeping the scan unit clean helps ensure the best possible copies. We 
suggest that you clean the scan unit at the start of each day and during 
the day, as needed.
1Slightly dampen a soft lint-free cloth or paper towel with water.
2 Open the scanner lid.
3Wipe the surface of the scanner glass and ADF glass until it is clean 
and dry.
4 Wipe the underside of the scanner lid and white sheet until it is 
clean and dry.
5 Close the scanner lid.
Maintaining the toner cartridge
Toner cartridge storage
To get the most from the toner cartridge, keep the following guidelines in 
mind:
• Do not remove the toner cartridge from its package until ready for use. 
• Do not refill the toner cartridge. The machine warranty does not cover 
damage caused by using a refilled cartridge.
• Store toner cartridges in the same environment as your machine.
• To prevent damage to the toner cartridge, do not expose it to light for  more than a few minutes.
Expected cartridge yield
The toner cartridge yield depends on the amount of toner that print jobs 
require. Average yield for a new toner cartridge is 3,000 standard pages in 
accordance with ISO/IEC 19752 standard. (Average yield for the original 
toner cartridge supplied with the machine is 1,500 standard pages.) 
The actual number may also be different depending on the print density of 
the pages you print on, and the number of pages may be affected by 
operating environment, printing interval, media type, and media size. If you 
print a lot of graphics, you may need to change the cartridge more often.

Redistributing toner
When the toner cartridge is near the end of its life:
• White streaks or light printing occurs. 
•Toner Low  appears on the display.
If this happens, you can temporarily reestablish 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 Open the front cover.
2 Pull the toner cartridge out.
3 Thoroughly roll the cartridge 5 or 6 times to distribute the toner 
evenly inside the cartridge.
Note
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.
Caution
Do not touch the green underside of the toner cartridge. 
Use the handle on the cartridge to avoid touching this area. 
4Hold 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 machine will guide the cartridge into the correct position until it 
locks into place completely.
5 Close the front cover. Make sure that the cover is securely closed.
Replacing the toner cartridge
When the toner cartridge is completely empty:
•Toner Empty  Replace Toner  appears on the display. 
• The machine stops printing. Incoming faxes are saved in memory. 
At this stage, the toner cartridge needs to be replaced. For order 
information for toner cartridges, see page 11.1.
