1.2 Toner Cartridge
Life expectancy: 6,500 pages / high-yield toner cartridge
3,300 pages / standard cartridge
(When printing A4 size paper at 5% print coverage)
NOTE:
•
The life of a new toner cartridge varies according to a print coverage ratio and a print job.
In the case of single-sided printing of typical business documents (at 5% print coverage)
on A4 size paper, up to 3,300 pages (standard cartridge) or 6,500 pages (high-yield toner
cartridge) can be printed.
•
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.
•
Wait to unpack the toner cartridge until immediately before you install it in the machine.
