Toner cartridge
A new toner cartridge can print approximately 3,500 (standard cartridge) or approximately 7,000 (high yield
cartridge) A4 or Letter size single-sided pages at 5% coverage.
Note
• The amount of toner used varies according to what is printed on the page and the print density setting.
• If you change the print density setting for lighter or darker printing, the amount of toner used will change.
• Wait to unpack the toner cartridge until immediately before you put it into the printer.

ready before you get a Toner Life End message. To replace the toner cartridge, see Replacing the toner
cartridge on page 63.
Note
The Toner LED will blink continuously if the toner cartridge is nearly empty.
