摘要:
A system for delivering at least two distinct pressures to a print head of an ink jet printer includes a pump, a passage in communication with the pump and the print head, and a valve. The pump is for delivering positive pressure to the print head of the ink jet printer. The passage includes an opening, and the valve selectively opens and closes the opening.
摘要:
A release agent applicator displaying decreased and consistent surface resistivity, and a method of making same. The release agent applicator includes an foam delivery surface having an ionic layer such that the surface resistivity of the delivery surface is reduced, thereby decreasing the chances of static charge accumulation on the roller that may interfere with high quality printing.

The present disclosure provides systems and methods for implementing an integrated imaging device. The device includes a scan-bar located along a media path in flow communication with an input tray, and a printing assembly associated with the media path. During a scan operation, the scan-bar scans a medium received along the media path from the input tray while the printing assembly is configured to be non-operational.

A method of servicing a customer replaceable unit of an imaging device includes providing a customer replaceable unit configured for insertion and removal from an imaging device. The customer replaceable unit includes at least an applicator configured to apply a release agent to a surface of an intermediate transfer drum of the imaging device, a reservoir including a supply of the release agent for the applicator, a delivery pump configured to pump release agent from the reservoir to the applicator, a recirculation pump configured to pump release agent from the applicator to the reservoir, and a memory including operational data for the customer replaceable unit. A maintenance procedure is then performed on the customer replaceable unit.
摘要:
A method of manufacturing an ink stick for use in a phase change ink jet imaging device comprises heating phase change ink material to an extrusion temperature at which the phase change ink material is in a malleable state. The heated ink material is then extruded through an extrusion orifice to form an extruded element. A forging element is then pressed against the extruded element to form an ink stick.

A method of manufacturing an ink stick for use in a phase change ink jet imaging device comprises heating phase change ink material to an extrusion temperature at which the phase change ink material is in a malleable state. The ink material is then extruded through an extrusion orifice to form an extruded rail of ink. The extruded rail of ink is then roll formed to partially form a portion of a shape transverse to the extrusion direction as the rail of ink moves in the extrusion direction. A swaging process is then carried out to further form and divide the extruded rail of ink into ink sticks.
摘要:
A system is provided for forming solid ink sticks comprising a molten ink delivery station for introducing molten ink material into a forming tub to form a solid ink stick. The forming tub includes an open top for receiving the molten ink material and a cavity defining a lower portion of a solid ink stick shape. The system includes a top surface conditioning station for altering the top surface of the ink material introduced into the cavity of the forming tub.
摘要:
A drum maintenance system for use in an imaging device includes a reservoir for the storage of release agent used by the drum maintenance unit. The reservoir includes a bottle, an end cap, and a float sensor. The float sensor has a buoyant member that is pivotably coupled to a proboscis extending from the end cap into the bottle and movement of the buoyant member enables detection of the release agent in the bottle reaching a predetermined level.
