Abstract: A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor to detect a position of a print media, a platform comprising at least one multi-rotational wheel, and a processor communicatively coupled to the at least one sensor and the at least one multi-rotational wheel, wherein the processor calculates a desired movement of the at least one multi-rotational wheel based on the position of the print media.

Abstract: A sheet registration system includes a transport member on which a sheet is conveyed in a process direction, a vacuum shuttle, and a feedback system. The vacuum shuttle includes a vacuum head which applies suction to the sheet and actuators for rotating the vacuum head in a plane parallel to a plane of the transport member and translating the vacuum head in a cross-process direction. In response to feedback instructions generated by the feedback system, the actuators move the vacuum head, relative to the transport member, while the vacuum is applied to the sheet. The sheet registration system is suitable for use in a printer for reducing skew and lateral offset of sheets of print media.

Abstract: A method of operating a printer enables activation signals of variable lengths to be generated for operation of a sintering head. The activation signals are generated with reference to a distance between activation signals for a first component to be a first determined distance and a duration of the activation signals for the first component to be longer than the first predetermined distance. This distance and duration are set to values that enable the generation of activation signals before the first predetermined distance is reached to maintain an activation signal until the generation of the activation signals is terminated. By generating a different number of activation signals, the duration of an initial activation signal can be varied.
