For optimum performance we recommend genuine toner by KYOCERA Document Solutions, which is specially designed for your printer. Toner particles of the incorrect size can lead to poor print quality with streaky grey background or ghosting on the page. KYOCERA Document Solutions toner contains ceramic cleaning beads which are essential to ensure the printer drum is clean and particle free. This is particularly important as our drums are designed to last several hundred thousand copies. A KYOCERA original toner will either have the KYOCERA Document Solutions logo moulded into the toner cassette or the toner will have a green KYOCERA Document Solutions label on it with white writing including our logo.
