Replacing the toner cartridge 
(TN-550/TN-580)

C

The TN-580 toner cartridge can print 
approximately 7,000 pages using a high yield 
toner cartridge. When the toner cartridge is 
running low, the LCD shows 

Toner Low

. 

The machine is supplied with a standard TN-
550 toner cartridge that must be replaced 
after approximately 3,500 pages. 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 up the toner 
cartridge tightly so that 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 machine 
and corona wire of the drum unit when you 
replace the toner cartridge. (See 

Cleaning the 

laser scanner window

 on page 128 and 

Cleaning the corona wire

 on page 130.)
