Abstract: 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.
