Abstract:
A printing system utilizing inks with high solids content includes a mixing unit for receiving a high solids content ink and producing a concentrated ink and an interim tank for receiving the concentrated ink from the mixing unit. An ink tank receives the concentrated ink from the interim tank and produces printing ink. An liquid electro-photographic print engine receives the printing ink from the ink tank. A fluid return line is connected between the mixing unit and at least one of the interim tank and the ink tank, the mixing unit receiving fluid from at least one of the interim tank and the ink tank and mixing the fluid with the high solids content ink. A method for liquid electro photographic printing using high solid content ink is also provided.
Abstract:
The present application relates to a method for concentrating an ink for an electrostatic printing process, wherein the method comprises the steps of: (a) providing the ink for an electrostatic printing process, the ink comprising chargeable particles in a liquid carrier; (b) passing the ink between a chargeable conveyor and a first electrode, wherein a potential is applied such that the ink becomes adhered to the chargeable conveyor; (c) passing the ink on the conveyor past a moving surface, wherein the ink contacts the moving surface and a potential is applied between the conveyor and the moving surface, such that the chargeable particles are disposed to move toward the conveyor and some of the liquid carrier is removed to increase the concentration of the chargeable particles in the liquid carrier on the conveyor to form a concentrated ink on the conveyor, the conveyor and the moving surface then diverging from one another, such that substantially all of the concentrated ink remains on the conveyor; (d) removing the concentrated ink from the conveyor and transferring it to a storage vessel. An apparatus for carrying out this method is also disclosed.

Abstract:
A method of heating toner of an image on a moving surface of an intermediate transfer member in order to transfer the image to a printing medium of a printing system comprising: providing a toner image on an intermediate transfer member; and placing a surface of a heated member in contact with said image on said intermediate transfer member, prior to transferring the toner image to a further surface from the intermediate transfer member.
Abstract:
An apparatus for use as an intermediate transfer member or fusing member in an image forming device includes a cylindrical member having a thickness that is insufficient to support it in use and which is secured between two round end plates to form a cylindrical structure which is unsupported between the endplates. A liquid is incorporated within the cylindrical structure and a heater is also located within the cylindrical structure so as to heat the liquid to produce a vapor wherein the vapor is of a sufficient pressure to support the cylindrical member during use.
Abstract:
An apparatus for driving a machine in a replaceable cartridge, the cartridge supporting a first rotatable element for transferring rotary motion to the machine, includes a housing for accommodating the cartridge at a pre-determined position. A second rotatable element is supported in the housing. A locking mechanism includes a component, provided on a certain one of the first and second rotatable elements, and capable of assuming a state of readiness in which, with the cartridge at the pre-determined position, the component is positioned relative to the other of the rotatable elements such that, upon rotation of the second rotatable element in at least a first direction, the first rotatable element rotates with the second rotatable element, and in which state the first and second rotatable elements are axially decoupled. The certain one of the first and second rotatable elements is provided with a mechanism for exerting a torque on the component tending to establish the state of readiness.
Abstract:
Apparatus for transferring visible images from a first surface to a second surface and/or for fusing or fixing a visible image to a substrate, comprising: a cylindrical member secured between two round end plates to form a cylindrical structure; a volatile liquid incorporated within the cylindrical structure in a cavity, at least one wall of which is thermally connected to the cylindrical member; and a heater that heats the liquid to an operating temperature, wherein the amount of the volatile liquid is such that all of the volatile liquid would be evaporated at a temperature that is less than about 20° C. above the operating temperature.
