ONER CARTRIDGE LIFE
How long your toner cartridge lasts depends on the print density; the percentage of the
page that prints black. A typical letter has 3% to 5% print density; graphics usually have
higher density. Higher print density means toner is used up faster.
The first toner cartridge installed in a new printer has to fill the image drum reservoir and
saturate the developing roller with toner. The toner cartridge that is supplied with this
printer normally produces about 1,500 pages after installation.
W
HEN TO REPLACE THE TONER CARTRIDGE
When the toner is running low, TONER LOW is displayed in the operator panel LCD. After
Toner Low displays, the printer will print about 100 more pages then display Toner Empty
and stop printing. Printing will resume after a new toner cartridge has been installed.
R
EPLACING THE TONER CARTRIDGE
It is recommended that you clean the LED array at the same time as you change the toner
cartridge.
The toner used in this printer is a very fine dry powder contained in the toner cartridge.
Have a sheet of paper handy so that you have somewhere to place the used cartridge while
you install the new one.
Dispose of the old cartridge responsibly, inside the pack that the new one came in. Follow
any regulations, recommendations, etc., which may be in force concerning waste recycling.
