Replacing the Toner Cartridge
The FAX/MFC can print approximately 2,200 pages with one toner cartridge.
When the toner cartridge is running low, the LCD shows
TONER LOW . The
MFC is supplied with a starter toner cartridge that must be replaced after 1,000
pages. Actual page count will vary depending on your average document type
(i.e. standard letter, detailed graphics).
It is a good idea to keep a new toner cartridge ready for use when you see the
TONER LOW warning.
Discard the used toner cartridge according to local regulations. If you are not
sure of them, call your local Sanitation Department. Be sure to seal the toner
cartridge tightly so toner powder does not spill out of the cartridge. When
discarding used toner cartridges, keep them separate from domestic garbage.
WARNING
Just after you have used the FAX/MFC, some internal parts of the FAX/MFC
will be extremely HOT! So, never touch the shaded parts shown in the
illustration.
Note
We recommend that you clean the FAX/MFC when you replace the toner
cartridge.
HOT!
