BDS and Kyocera recommend changing the waste toner bottle every time the black toner is empty on Kyocera TASKalfa Machines.
A collection of articles on changing the waste toner box for Kyocera. Kyocera has improved both the design and efficiency of its black and waste toner bottles. To achieve this, they redesigned the bottles to be identical, and the empty black toner will become the new waste toner bottle. This will cut down on unnecessary waste and eliminate the need to store an entirely separate bottle on-site for the waste toner.
