An filtration apparatus is disclosed. The filtration apparatus is to remove non-liquid contaminant from liquid carrier. The filtration apparatus may include an electrode having a first surface, wherein the electrode is to generate an electric field towards liquid carrier containing non-liquid contaminant. The filtration apparatus may include a reservoir having a wall defined at least partially by the first surface, the reservoir to house a volume of liquid carrier. The filtration apparatus may include a plurality of plates, each plate having an accumulation surface, wherein a portion of each plate is within the reservoir, so as to be submerged in the volume of liquid carrier. An electric field formed between the first surface and the accumulation surface of each plate of the plurality of plates may act on the liquid carrier, to thereby cause non-liquid contaminant to adhere to an accumulation surface of a plate of the plurality of plates. A method and a print apparatus are also disclosed.

Liquid carrier filtration

An example cleaning station for a liquid electrophotographic printer is described. The cleaning station has a first cleaning member, a second cleaning member, and a biasing member. The cleaning station is configured to move between a first position and a second position with respect to a photo imaging member of the printer. In the first position, the first cleaning member is arranged to remove particles from the photo imaging member of the printer and the second cleaning member is arranged to apply a force to a layer of liquid applied to the photo imaging member. In the second position, the biasing member is configured to cause the second cleaning member to contact the first cleaning member to clean the second cleaning member.

Cleaning a liquid electrophotographic printer

A cleaning unit for removing debris from an ink transfer surface includes a cleaning roller having: a microcellular material outer layer; a wetting module to supply cleaning fluid to the microcellular material outer layer of the cleaning roller; and an extractor to remove cleaning fluid and debris from the cleaning roller.
