Abstract

A method of maintaining a photoconductive member of a liquid electrophotography printing apparatus (LEP) is disclosed. The method includes storing a fluid having at least fluid particles and a carrier liquid in a fluid chamber and removing at least a portion of the fluid particles and the dissolved materials from the fluid through adsorption by filtration material disposed within a filtration assembly to form a filtered fluid. The method also includes maintaining the photoconductive member by periodically applying the filtered fluid to the photoconductive member and removing the filtered fluid and fluid residue therefrom.
