Abstract: A direct-to-object printer includes an object rotating subsystem. The object rotating subsystem includes an actuator with an output shaft, a holder mounted to the output shaft, the holder being configured to grip a portion of the object, and a controller operatively connected to the actuator. The controller is configured to operate the actuator to rotate the holder and the object gripped by the holder to enable at least one of the printheads in a printer to print a portion of a circumference of the object that is longer than a width of the at least one printhead.

Abstract: A thin-walled fuser roll core cylinder assembly permitting fast warm-up times and improved energy efficiency wherein cracking of the thin walls of the core cylinder due to cyclic compression is prevented by redirecting axial stress at the terminus of an axial keyway to a radial direction. The keyway is for coupling the core cylinder to a drive gear. Use of such a thin-walled fuser roll in an imaging system and a process of fusing toner onto a copy substrate using the thin-walled fuser core.

Abstract: A thin-walled fuser roll core cylinder assembly permitting fast warm-up times and improved energy efficiency wherein cracking of the thin walls due to cyclic compression is prevented by strengthening the thin walls proximate to the end region where the core cylinder is engaged by the drive gear. Use of such a thin-walled fuser roll in an imaging system and a process of fusing toner onto a copy substrate using the thin-walled fuser core.

Abstract: Rolls include a core and a glass outer coating on the core. The glass can be electrically charged and discharged. The outer coatings have smooth finishes and controlled electrical properties. The outer coatings can also provide selected mechanical, chemical and thermal properties. The rolls can be used in various applications in which controlled electrical properties are desired. For example, the rolls can be used as charge donor rolls in electrostatographic imaging apparatus.

Abstract: A roller assembly for use in an electrostatographic development apparatus to transport developer material through a development zone. The roller assembly includes end cap sections for mounting rotatably to a housing of the development apparatus, and a spincasted sleeve section interconnecting the end cap sections. The spincasted sleeve section includes an outer layer that has a series of non-radial undercuts formed thereinto for retaining developer material being transported. In order to achieve consistent precision at relatively lower costs, the sleeve section is produced by spincasting a desired quantity of filled thermoset material in a simple reusable silicone mold formed and held in a mud frame.
