Replacing the toner cartridge
(TN-350)
The toner cartridge can print up to 2,500
pages. When the toner cartridge is running
low, the LCD shows Toner Low. Actual page
count will vary depending on your average
type of document (i.e., standard letter,
detailed graphics).
Note
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, keeping it separate from
domestic waste. Be sure to seal the toner
cartridge tightly so toner powder does not
spill out of the cartridge. If you have
questions, call your local waste disposal
office.
We recommend that you clean the MFC and
drum unit when you replace the toner
cartridge. (See Cleaning the laser scanner
window on page 11-23 and Cleaning the
drum unit on page 11-17.)
