    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 apparatus is provided in accordance with the present disclosure, which may be used for example for liquid electrophotographic printing. The example apparatus includes a photo imaging plate to receive a liquid colorant image, the liquid colorant including a carrier fluid, and to transfer the image to a support, and a rotatable roller to remove carrier fluid from the photo imaging plate and increase the density of solids in the liquid colorant on at least a region of the photo imaging plate, prior to the liquid image being transferred.

    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.

    摘要： During a print cycle of a print apparatus, a liquid print agent including a carrier fluid is applied to a photoconductive surface. A proportion of the carrier fluid in the liquid print agent on the photoconductive surface is reduced at a first location by removably collecting a portion of the carrier fluid from the liquid print agent applied to the photoconductive surface. During a non-print cycle of the print apparatus, the removably collected portion of the carrier fluid is added to the photoconductive surface at the first location.
