Abstract: The present disclosure relates to controlling a performance characteristic of an image forming device component having a surface which may include removal of a portion of the surface to expose a plurality of voids and a surface between the voids. The surface between the voids may have a surface roughness Ra in the range of 0.1 to 5.0 microns and the relationship SAV/(SAV+SAC) is equal to 1-50%, where SAV is the surface area of the voids and SAC is the remaining surface area of the component. The performance characteristic may include the control of toner mass conveyed and/or toner filming and/or the amount of residual toner removed from a photoconductive surface.

Abstract: Embodiments for toner supply members, particularly toner supply member properties and architectures for controlling toner layer thickness supply to the developer member in image forming devices. In one embodiment the toner supply members have a foamed elastic body.

Abstract: A layered intermediate used in inkjet printing contains a release coat formed on a transfer medium in an area where an image has not been printed. The release coat is formed of polyvinyl pyrrolidone (PVP) or a PVP copolymer and at least one solvent selected from the group consisting of glycol solvents and diol solvents. A viscous coating of PVP or the PVP copolymer is formed on the transfer medium in an area where an image has been printed. A release layer formed from components in the release coat and components in the ink is formed on the viscous coating. A first ink layer is formed on the release layer of flocculated ink. A second ink layer is formed on the first ink layer, of ink that is substantially not flocculated.

Abstract: A dry time sensor apparatus for an ink jet printer includes a light source emitting light onto a selected area of ink on a print medium such that the light reflects off of the selected area of ink. A reflective device receives the reflected light and reflects the light a second time back onto the selected area of ink such that the light is reflected a third time by the selected area of ink in a predetermined direction. The predetermined direction is substantially nonvarying over a range of angles of orientation of the print medium and a range of distances of the print medium from the light source. A reflected light detecting device receives the light reflected in the predetermined direction.

Abstract: Mirror (1) of a laser printhead has an octagonal outer configuration. During normal use the mirror is rotated at high speed, which drives ambient air which causes noise. To control the noise a shroud (11) surrounds the mirror and confines the air except at an opening in the shroud to permit a laser beam to reach the mirror and be reflected out. A rib extends over the mirror and near the area of the opening, positioned to reduce sounds created by the assembly.
