! Toner Cartridge
A new toner cartridge contains enough toner to print up to 6,500 A4/Letter-
size single-sided pages at 5% coverage (if the print density is set at level 0).
✒ ✒ ✒ ✒ Note
• The amount of toner used varies according to what is printed on the
page and the print density setting.
• The more that is printed, the more toner will be used.
• If you change the print density setting for lighter or darker printing, the
amount of toner that is used will change (more for darker printing).
• Do not unpack the toner cartridge until immediately before you are to
use it in the printer.
