Replacing the toner cartridge
TN-2000
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. You can also check our
ecology website www.brothergreen.co.uk for
recycling information. 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 machine
and drum unit when you replace the toner
cartridge. (See Cleaning the laser scanner
window on page 11-23 and Cleaning the
corona wire on page 11-24.)
