i ordered one toner from you sometimes ago, i found it only use a short time and the printer said use 30% off. do i receive a defective one from you?
The page yield is at 5% page coverage.
Toner use is by how much toner is placed on each page printed and how many you print. Depending on your printer make, model and toner cartridge size along with toner coverage per page, determines how many pages you'll get out of it.
