Abstract: A registration system includes nip rollers for conveying a sheet in a process direction when the nip rollers are in an engaged position, and first and second sets of omnidirectional rollers arranged perpendicularly to each other, for conveying the sheet in the process and cross-process directions, respectively. The omnidirectional rollers each allow the sheet to slide, relative to the omnidirectional roller, in a direction parallel to an axis of rotation of the omnidirectional roller. The nip-rollers are movable from the engaged position to a disengaged position, in which the first pair of omnidirectional rollers convey the sheet in the process direction. A feedback system includes sensors for determining registration errors of the sheet and a control system controls the omnidirectional rollers to reduce the registration errors in the sheet while the nip-rollers are in the disengaged position.

Abstract: What is disclosed is an object holder for retaining an object in a direct-to-object print system and a direct-to-object print system configured to use various embodiments of the object holder of the present invention. In one embodiment, the object holder has a back support configured to slideably traverse a support member positioned parallel to a plane formed by at least one printhead configured to eject marking material on to a surface of an object. A top and bottom arm are attached to the back support. At least one retention bit is attached to each of the top and bottom arms for collectively retaining the object to the object holder.
