™ Toner cartridge
A new toner cartridge contains enough toner to print approximately 6,500
A4/Letter-size single-sided pages at about 5% coverage (if the print density
is set at level 0).
✒ ✒ ✒ ✒
Note
• Toner consumption varies according to the image coverage on the page
and the print density setting.
• The greater the image coverage, the greater the toner consumption.
• If you change the print density setting for lighter or darker printing, toner
consumption varies accordingly.
• Wait to unpack the toner cartridge until immediately before you install it
in the printer.
