TONER CARTRIDGE LIFE How long your toner cartridge lasts depends on the print coverage; the percentage of the page that prints black. A typical letter has 3% to 5% print coverage; graphics usually have higher coverage. Higher print density means toner is used up faster. At 5% print coverage, a standard toner cartridge will print an average of 2500 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 first standard toner cartridge normally produces about 1,000 pages after installation. CONSUMABLES AND MAINTENANCE > 66
