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.
