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.)
