摘要:
An approach is provided for contact leveling an image applied to a media substrate. The approach involves causing, at least in part, a contact leveling member comprising at least one textured surface configured to repel one or more inks to level an image applied to the media substrate. The at least one textured surface may comprise one or more micro/nano structures configured to cause, at least in part, the at least one textured surface to have an ink contact angle greater than 100° and a sliding angle less than 30° when the at least one textured surface contacts the one or more inks.

The present disclosure provides a method for controlling printing in a solid ink jet printing system. The method comprises forming a first ink image and a second ink image on a transfer surface; passing a receiving substrate through a first nip simplex path of a first ink jet printer at a first print speed; exerting a first pressure on the receiving substrate in the first nip to transfer the first ink image from the transfer surface to a first side of the receiving substrate; moving the receiving substrate through an inverter path; passing the receiving substrate through a second nip simplex path of a second ink jet printer at a second print speed; and, exerting a second pressure on the receiving substrate in the second nip to transfer the second ink image from the transfer surface to a second side of the receiving substrate.

An improved development station extends the useful life of toner in the housing and increases the number of images developed by the developer supply. The improved development station includes a toner supply for providing toner to a developer sump; a mixing auger for uniformly blending and charging toner particles supplied by the toner supply into the developer material; a magnetic roller for receiving the developer material and bringing the developer material into contact with a photoreceptive member, and a variable developer material restrictor for variably restricting flow of developer material to vary the mechanical stress delivered to the developer material.

A method of operating an inkjet imaging device more thoroughly cleans residual ink from an intermediate imaging member and disrupts any ghosted images that may have formed in the release agent.
摘要:
A process for preparing an imaging surface of an imaging transfer member in a printing machine, the process comprises providing a surface roughness to the imaging surface to produce a plurality of pits having sharp features on the surface, and then exposing the pitted imaging surface to an acid dip for a time period sufficient to substantially reduce the sharp features on the imaging surface. This process may be followed by anodization. The process produces an imaging surface having a pit structure providing reduced oil consumption and wear of components of the printing machine that contact the imaging surface.

A release agent applicator applies release agent to an imaging drum and absorbs release agent metered from the drum to extend the operational life of a image drum maintenance unit. The applicator includes a reservoir for storing release agent, the reservoir having a plurality of perforations for enabling release agent to seep from the reservoir, a containment membrane mounted to the reservoir for wicking release agent from the perforations of the reservoir, and a delivery layer mounted to the containment membrane for delivering release agent from the containment membrane to an imaging drum that is in contact with the delivery layer. The delivery layer is matched to the containment membrane to maintain a saturation rate for the delivery layer in a predetermined range and the delivery layer has an uptake rate for release agent contacting an external boundary of the delivery layer that is greater than a release agent supply rate from the containment membrane to the delivery layer.
摘要:
A process transfers an image from an intermediate imaging member onto a sheet of recording media while preserving the ability to duplex print on the sheet. The process includes generating an image on an intermediate imaging member as the intermediate imaging member rotates in a first direction, synchronizing a sheet of recording media with the image on the intermediate member as the intermediate imaging member continues to rotate in the first direction, transferring the image from the intermediate imaging member onto the sheet of recording media as the intermediate imaging member continues to rotate in the first direction, and limiting release agent on the intermediate imaging member to a level that preserves duplex printing capability on the sheet of recording media.
摘要:
An apparatus for developing a latent image recorded on a movable imaging surface, including: a reservoir for storing a supply of developer material including toner particles, said reservoir including a transport member; a donor member being arranged to receive toner particles from said transport member and to deliver toner particles to the image surface at locations spaced apart from each other in the direction of movement of the imaging surface thereby to develop the latent image thereon; a power supply, connected to said donor member, for biasing said donor member to deliver toner to the image surface during a printing mode of operation; a second power supply, connected to the transport member, for maintaining a predefined voltage difference between the transport member and the donor member such that toner particles are attracted to the donor member from the transport member during a printing mode of operation; a controller for generating a donor member purge signal trigger based on sensed or calculated development conditions; and a power supply controller, responsive to said donor member purge signal, for changing the voltage between the donor member and the transport member during a second mode of operation thereby causing toner to partially or completely transfer back to said transport member and optionally transported to the imaging surface.
