摘要： In an example, a method includes applying a liquid print agent comprising a carrier fluid to a photoconductive surface and reducing a proportion of the carrier fluid in the liquid print agent on the photoconductive surface at a first location during a print cycle of a print apparatus. The method may further include, during a non-print cycle of the print apparatus, adding carrier fluid to the photoconductive surface at the first location.

摘要： An example method of performing a null cycle in a liquid electrographic printer is described. The method involves collecting, at a photo imaging plate cleaning station, imaging oil deposited on a photo imaging plate during a print cycle. During a null cycle, the photo imaging plate cleaning station is controlled to apply the collected imaging oil to the photo imaging plate.

摘要： In certain examples, a liquid electrophotographic printer has a compressive element. The compressive element removes a portion of carrier liquid from an inked image on an imaging element. The compressive element is selectively engageable and a controller disengages the compressive element for a first layer of liquid toner so as to retain carrier liquid in the first layer, and engages the compressive element for a subsequent layer of liquid toner so as to remove a portion of carrier liquid from the subsequent layer.
