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 124 and
Cleaning the corona wire on page 126.)
