Abstract: A method is disclosed. The method may comprise applying a coating of electrically charged fluid print agent to a developer surface, the fluid print agent comprising particles of thermoplastic resin in a carrier fluid. The method may further comprise controlling migration of fluid print agent from the developer surface to form an image from fluid print agent on a first surface. The method may further comprise irradiating the print agent on the first surface with ultraviolet radiation to heat the print agent to a temperature of at least 70° C. to melt the thermoplastic resin. A print system and a heating unit are also disclosed.

Abstract: In an example of the disclosure, a blanket servicing system includes a rotatably mounted endless cleaning surface and a scraper. The endless cleaning surface is to have a first engagement with a blanket to obtain a layer of thermoplastic print agent from the blanket. The endless cleaning surface is to have a second engagement with the blanket to receive residue from the blanket onto the layer of thermoplastic print agent. The scraper is to scrape the endless cleaning surface to transfer the residue from the endless cleaning surface to a collection element.

Abstract: In an example, a print apparatus comprises an intermediate transfer member to receive thermoplastic print agent from a photoconductive surface, a rotatably mounted endless cleaning surface to receive a layer of thermoplastic print agent from the intermediate transfer member and a heater, to heat the endless cleaning surface. The endless cleaning surface may be to engage with the intermediate transfer member when heated to transfer residue from the intermediate transfer member to the layer of thermoplastic print agent on the endless cleaning surface.
