Abstract: An apparatus for maintaining a uniform temperature along its axis by increasing the heat transfer efficiency. The apparatus uses a sealed chamber containing a substantially pure working fluid in a two phase (liquid and vapor) condition. The vaporization and condensation of the fluid increases the heat transfer efficiency and tends to equalize temperature gradients in a body in contact with the apparatus. The apparatus is utilized in various locations in an electrophotographic printing machine and can be used as a pressure roll for a heat and pressure fuser, a support or drive roll for a photoreceptive member, a support member for a photoreceptor and a heat sink for a developer housing.

Abstract: A printing machine of the type having a plurality of components for printing a document is disclosed. The printing machine includes an air source and a support member having a component mounted thereon. The support member is coupled to the air source which has output ports so that air flows from the output ports.

Abstract: An apparatus in which sheet material is decurled. The apparatus includes a rod deflecting a belt to define a nip therebetween. The belt is entrained about a part of spaced rollers. A pair of baffle plates are located at the entrance to the nip and at the exit to the nip. The rod is adapted to translate in a vertical direction. As the rod translates, the degree of deflection is varied and the bend of the sheet adjusted. The baffle plates at both the exit and entrance regions to the nip pivot in unison with the translation of the pivot rod so as to adjust the orientation of the sheet entering and leaving the nip.
