When you notice faded text or foggy backgrounds on prints from your OKI C710/C711 printer, install a genuine OKI Black Toner Cartridge (44318608) and enjoy great quality, consistent printing once again. When the current toner cartridge is running low, you'll see a Toner Low message on your printer's display. Order a new cartridge as soon as possible and install it when you see the message Toner Empty. This standard yield toner cartridge is packed with enough black toner to print 11,000 pages.
