Methods of manufacturing toner for use in electrophotographic imaging members, such as photoreceptor structures. More particularly, embodiments pertain to an apparatus and process for separating toner from toner/carrier mixtures, such as reclaiming toner from waste toner, much more efficiently and with improved yields.

Apparatus and process to reclaim toner from a toner/carrier mixture

A method for cleaning portions of a particle classifier, such as for example the rotor and/or stator, includes providing carbon dioxide particles to the classifier. Carbon dioxide particles are supplied to the classifier via a particle inlet and subjected to processing conditions similar to those utilized in particle classification. Cleaning a classifier with carbon dioxide particles may be accomplished off-line or on-line.
