Abstract: In one example of the disclosure, a first transfer of ink is made from a photoconductor to a blanket in contact with the photoconductor. The blanket is to cycle along a path. The first transfer occurs at a first arc of the blanket path. A second transfer of the ink is made from the blanket to a media in contact with the blanket. The second transfer occurs at a second arc of the blanket path. A heat source located adjacent to a third arc of the blanket path is utilized to heat an external surface of the blanket. The heating is to occur following the second transfer of the ink.

Abstract: Aspects presented herein are directed towards a carrier evaporator for a Liquid Electrophotography Printing (LEP) system. In an example, the carrier evaporator provides a hot air supply to absorb an evaporated carrier liquid resulting in first air flow comprising a carrier vapour, an evacuator to evacuate at least a portion of the carrier vapour, a heat exchanger to decrease a temperature of the remaining carrier vapour thereby transforming the first air flow to a second airflow comprising carrier particles, and a filter to remove the carrier particles from the second air flow.

Abstract: An example method of collecting liquid carrier from a vapour in a printing system includes: heating a vapour carrying a liquid carrier and passing the heated vapour carrying liquid carrier through a volume of liquid carrier. Liquid carrier carried in the heated vapour condenses into the volume of liquid carrier as it passes through the volume of liquid carrier.

Abstract: In an example, a condenser apparatus to condense vapored fluid has a gas inlet, a mesh, a cooling element, and a gas outlet. The mesh is configured to carry a layer of condensed fluid. The cooling element is configured to cool the layer of condensed fluid. The mesh is configured to let pass through vapored fluid and to create bubbles including vapored fluid in the layer of condensed fluid.
