Abstract: An imaging apparatus includes an imaging member having a surface, a delivery member that is spaced apart from the imaging member, and a power source for generating an electric field between the imaging member surface and the delivery member. A functional material is electrohydrodynamically transferred from the delivery member to the imaging member surface when the electric field is generated.

Abstract: Methods for lubricating an imaging member include applying lubricant-containing capsules to the surface of the imaging member via a non-contact applicator. The capsules are applied upstream of a cleaning blade after image transfer to another substrate, such that the cleaning blade ruptures the capsules, thereby releasing the lubricant contained therein.

Abstract: A vibration-assisted bias charge roll cleaning system includes a bias charge roll cleaning member connected to an actuator for causing the cleaning member to vibrate. The actuator is controlled to vibrate according to a predetermined pattern, and at desired frequencies at particular modes. The cleaning member is configured to be movable to a contact-cleaning position and a cleaning member cleaning position at which the cleaning member is separate from the charge roll.

Abstract: An method for operating an object printing system printer prints electrical circuits on non-planar areas of objects and accurately places electronic components within the printed circuits. The method includes operation of a direct-to-object printer to form an electrical circuit on an object secured within the direct-to-object printer and operation of an electronic component placement system to retrieve an electronic component and install the electronic component in the electrical circuit on the object secured within the direct-to-object printer in response to a generation of a signal by the direct-to-object printer for the electronic component placement system that indicates the electronic component is to be installed in the circuit on the object secured within the direct-to-object printer.

Abstract: There is described an a bias charge roller including an electrically conductive core and an outer layer axially supported on the core. The outer layer includes a continuous raised pattern above a non-contact surface wherein the continuous raised pattern includes a contact surface having a height of from about 10 microns to about 40 microns above the non-contact surface. The outer layer transitions from the contact surface to the non-contact surface over a minimum linear distance of 100 microns or greater. The contact surface is configured to contact a charge-retentive surface of an electrophotographic imaging member so as to charge the charge-retentive surface.
