Abstract:
1. A liquid electrophotography printing apparatus (LEP), comprising: a photoconductive member having a surface to form a latent image thereon; a fluid chamber to store fluid having at least fluid particles, dissolved materials and a carrier liquid; a filtration assembly in fluid communication with the fluid chamber, the filtration assembly to store filtration material to remove at least a portion of the fluid particles and the dissolved materials from the fluid from the fluid chamber to form a filtered fluid; a detector assembly to detect at least one fluid parameter of the fluid; a filtration adder unit to automatically add a predetermined amount of the filtration material to the filtration assembly based on the detection of the at least one fluid parameter; and a maintenance unit to periodically apply the filtered fluid from the filtration assembly to the photoconductive member and to remove at least the filtered fluid from the photoconductive member.
