Abstract: In an example of the disclosure, a system to service a print blanket includes a rotatably mounted endless cleaning surface (“ECS”), a doctor blade, a heating element, and a container. The ECS is to carry a polymeric material and positioned to engage the print blanket. The doctor blade is disposed in relationship to the ECS and to a container to scrape a portion of the polymeric material from the ECS into the container. The heating element is to heat the container. The container is positioned to collect the scraped portion of polymeric material, and make heated polymeric material available to be picked up by the ECS as the ECS is rotated adjacent to the container.

Abstract: According to an example, a photoconductive drum support comprises a receiving body to receive a photoconductive drum, a rear cup coupled to a first end of the receiving body, a locking member rotatably coupled to a projecting portion of the receiving body, and a front cup positioned to contact a second end of the receiving body. The locking member is movable between an unlocked position in which the front cup is movable along the projecting portion and a locked position in which the locking member is positioned to fix the front cup and the rear cup at a predetermined distance.

Abstract: In one example a fluid ejection device comprises a housing and a deflector arm. The housing comprises a first housing portion and a second housing portion defining a fluid ejection aperture therebetween. The fluid ejection aperture is to direct fluid towards a roller. The deflector arm is movable within the fluid ejection aperture between first and second positions. In the first position, the deflector arm is proximate the second housing portion to thereby direct fluid between the deflector arm and the first housing portion and toward a target area on a surface of the roller. In the second position, the deflector arm is proximate the first housing portion to thereby direct fluid between the deflector arm and the second housing portion. The second housing portion comprises a curved surface such that, when the deflector arm is in the second position, fluid is directed away from the target area.
