Abstract: In one example, a document scanner has a fixed-position scan bar and a built-in translatable calibration target. The scan bar has a linear array of imaging elements aimed in an imaging direction. The calibration target is spaced apart from and parallel to the linear array, and has a planar surface orthogonal to the imaging direction spanning the length of the linear array. The target is translatable during a calibration in a direction in a plane of the surface.

Abstract: According to one example, there is provided a method of generating three-dimensional objects in a three-dimensional printing system comprising a pair of movable build modules. The method comprises moving a first build module into a build position, executing a 3D print job in the first build module, moving the first build module into a post-build position, performing post-processing operations on the first build module, moving a second build module into the build position, and executing a 3D print job in the second build module.

Abstract: In one example, a media feed system includes a pick arm that is adjustable at a pivot and operable to maintain a distance between a pick roller and a separation wall as the pick arm changes orientation. In another example, a media feed system may include a pick arm, a pick roller coupled to the pick arm, a pivot coupled to the pick arm, and a plate coupled to the pivot via a pin and slot interface. In that example, a slot of the pin and slot interface is to adjust position of the pivot and adjust orientation of the pick arm.

Abstract: In one implementation, a system for a partially dried inkjet media finisher includes a media input zone to receive printed media, wherein the printed media is partially dried inkjet media, a transport zone to receive the printed media from the media input zone to lower the print media to an accumulation zone that is coupled vertically below the transport zone, wherein the accumulation zone organizes the received printed media, and the accumulation zone to lower the printed media to an output zone coupled vertically below the accumulation zone, wherein the output zone receives a completed print job from the accumulation zone.

Abstract: A printing device includes, in one example, a media output system including a mezzanine level including a plurality of media support members, the mezzanine level being intermediate to a floor level and a media output level; wherein the plurality of media support members move orthogonally relative to a print media path so that a number of finishing processes may be performed on print media accumulated on the number of media support members.
