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.
