About:Take a look at my web page and see more about the amazing Kyocera Tk-170 Toner Cartridge. For optimum performance I suggest genuine TK-170 toner by KYOCERA Document Solutions, that is specifically designed to be used by your printer. Toner particles of the incorrect specifications could result in unsatisfactory print quality with streaky grey background or even ghosting on the page. KYOCERA TK-170 toner consists of ceramic cleaning beads which are essential to ensure the printer drum is clean and fragment free. This is particularly important as our drums are designed to last several hundred thousand copies. A KYOCERA genuine TK-170 toner will either have the KYOCERA Document Solutions logo moulded into the toner cassette or the toner will have a green KYOCERA File Solutions label on it with white composing including our logo.
