Keep your Kyocera FS-720 or FS-1016MFP series laser printer operating for longer, with crisp high quality prints, by installing a genuine Kyocera Black Laser Toner Kit (TK110). If the red Attention light on your Kyocera printer starts flashing slowly or you see the message Toner Low, it may mean you need to order a new toner cartridge. The light will turn solid red or the display will show Please Replace Toner when you need to swap out the empty cartridge. This high yield cartridge contains even more toner for printing up to 6,000 pages.
