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.

Abstract: An example apparatus for determining dryness of an agent on print media includes an infrared prism, a source of infrared radiation to direct infrared radiation into the infrared prism, and a detector. The infrared prism includes a surface, the surface having an outer side to contact a portion of the agent on the print media, the infrared prism having a refractive index that is higher than a refractive index of the agent. The source of infrared radiation is to direct infrared radiation into the infrared prism and onto an inner side of the surface. The detector is to generate a signal based on infrared radiation reflected by the inner side of the surface to indicate the dryness of the portion of the agent.
