For optimum performance we recommend genuine KYOCERA toner, 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 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. Import charges may apply to your purchase.
