Abstract: Examples of a platen for a printing device are described. In some examples, the platen may include a spit opening located at a side of the platen. In some examples, the spit opening may include an angled lead-in edge to facilitate travel of print media in the printing device. In some examples, an inside portion of a leading edge of the print media contacts the angled lead-in edge of the spit opening and pulls an outside edge of the print media up as the print media moves across the platen.

Abstract: A base device to support a finisher includes a base pan, a first plurality of casters coupled to the base pan, a second plurality of casters coupled to the base pan, and a recess to receive a tip foot. The base pan includes a section which protrudes outward from a first side of the base pan. The first plurality of casters are coupled to the base pan to contact a surface when the base pan is level with respect to the surface, each of the first plurality of casters being beside a respective separate corner of the base pan and at least two of the first plurality of casters being beside the section. The second plurality of casters are to be positioned above the surface when the base pan is level with respect to the surface and to contact the surface when the base pan is inclined to a threshold.

Abstract: A heating roller for a wet ink-based image forming apparatus includes a roller having a contact surface to contact a print medium having wet ink deposited thereon by wet ink-based image forming apparatus. The heating roller conductively heats the print medium and dries and flattens the print medium. The heating roller includes a heating element embedded along the roller. The heating element rotates with the roller as the roller rotates. The heating element generates and conducts heat to the contact surface so as to conductively heat the print medium through the contact surface when the contact surface contacts the print medium.

Abstract: An example device includes a conveyor to convey a printed medium along a path from a print engine towards a printed media output. The device further includes a housing to hold the conveyor. The housing defines an air intake, an exhaust port, and a conveyor volume to contain the conveyor. The air intake provides air to the conveyor volume to dry the printed medium. The device further includes a tortuous exhaust passage extending from the conveyor volume to the exhaust port to exhaust air from the conveyor volume.
