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.
1 Slightly dampen a soft lint-free cloth or paper towel with water.
2 Open the scanner lid.
3 Wipe 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.
