TONER 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. At 5% print density, a standard toner cartridge will print an average of 3500 pages. Remember, this is only an average:actual results may vary. 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. WHEN 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. REPLACING THE TONER CARTRIDGE WARNING > Never expose a toner cartridge to an open flame. It can cause an explosion and you can be burned. > Be sure to switch off and unplug the machine before accessing the interior of a machine for cleaning, maintenance or fault clearance. Access to a live machine's interior can cause electric shock. 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. Consumables and maintenance > 61
