Abstract

A liquid electro-photographic, LEP, printing system, comprising a photo imaging plate, PIP, an intermediate transfer member, ITM, and a control unit. The control unit causes the system to initiate a maintenance program, wherein the maintenance program comprises driving the PIP and the ITM while disabling particle transfer to the PIP and applying a voltage difference between the PIP and surface portions of the ITM.
