摘要:
In a tonerless imaging process, an inked image layer jetted on an image receptor is simultaneously transferred and fused to a recording medium. A radiation-curable material is incorporated in the image layer such that irradiation of the image layer cures the radiation-curable material therein. An ink jet printing apparatus for performing the above process is also disclosed.

A fusing member is formed from an evacuable inner tube with a cylindrical wall. The evacuable inner tube is inserted into an outer tube and the inner tube is pressurized to expand the inner tube such that the wall is in contact with the outer tube. An amount of a working fluid is then sealed within the inner tube at a below atmospheric pressure.

Apparatuses useful for printing and methods of fixing marking materials onto media are disclosed. An exemplary embodiment of the apparatuses useful in printing includes a first member including a first surface; a second member comprising at least one ferromagnetic material having a relative magnetic permeability greater than 1, a susceptor over the at least one ferromagnetic material, the susceptor comprising at least one electrically resistive metal, and a second surface over the at least one ferromagnetic material and the susceptor, the second surface forming a nip with the first surface at which media are received; and a magnetic field generator for generating a magnetic field to inductively heat the second member.

A coated member includes a substrate and a coating layer over the substrate where the coating layer includes at least one of ferromagnetic and magnetic particles dispersed in a binder. The member, which is suitable for use in an electrostatographic printing process, can be in the form of a fuser member, a fixing member, a pressure roller, or a release agent donor member.

An enhanced sheet stripping method and apparatus for stripping toner image carrying copy sheets from a surface of a moving heated fusing member forming a fusing nip. The apparatus includes (a) a moving assembly for moving a cut sheet towards the fusing nip; (b) a sheet curling device positioned upstream of the fusing nip relative to movement of the cut sheet for inducing a desired pre-curl in the cut sheet before the cut sheet enters the fusing nip; and (c) a sheet stripping device positioned downstream of the fusing nip for stripping the cut sheet from contact with the surface of the moving heated fusing member as the cut sheet exits the fusing nip. The method includes inducing a desired curl in the cut sheet before the cut sheet enters the fusing nip and enhanced stripping the cut sheet from contact with the surface of the fuser roll as the cut sheet exits the fusing nip.
摘要:
A system includes at least one movable image bearing member transporting a latent image in an electrophotographic printing system. A developer station associated with the at least one image bearing member deposits a developed image on the latent image. The developed image includes toner particles and carrier liquid. A transfer station associated with the at least one image bearing member transfers the developed image to a receiving medium. A liquid removal station disposed between the developer station and the transfer station includes a source of high fluid pressure emitting an open-air jet of fluid for directly and/or indirectly removing at least a portion of the carrier liquid from the developed image.

Methods and apparatus for performing addressable fusing and/or heating of a substrate undergoing xerographic processing are disclosed. The apparatus includes a fuser having an array of addressable heating elements in radiative communication with a substrate through a fuser roll or fuser belt. The array of addressable heating elements is operated to selectively heat portions of the substrate to achieve a desired effect on the substrate, such as changing its surface finish, or fusing unfused toner to the substrate. In the case of toner fusing, the array is operated such that substantially only an area covered by the unfused toner is heated. This eliminates the need for blanket fusing, and generally provides for greater flexibility in xerographically processing substrates. Apparatus and methods for performing two-sided selective fusing and/or heating are also disclosed.

An electrostatographic reproduction machine including a contact belt fusing apparatus for fusing copy sheets without belt skew defects. The fusing apparatus includes an endless fusing belt having an external fusing surface defining a path of movement and a plurality of support rollers for supporting and moving the endless fusing belt along the path of movement. The endless fusing belt as supported has a preferred fusing position properly aligned on the plurality of support rollers. The fusing apparatus includes a pressure roller forming a fusing nip with the external fusing surface of the endless fusing belt for contacting and moving toner image carrying sheets therethrough. Importantly, the fusing apparatus also includes a dual function belt deskewing and heating assembly for heating the external fusing surface of the endless fusing belt and deskewing the fusing belt from a sensed skewed position to the preferred fusing position. The dual function belt deskewing and heating assembly includes a heated roller for contacting and heating the fusing belt, and skewing means for skewing the heated roller to controllably move the endless fusing belt in a deskewing manner from a sensed skewed position to the preferred fusing position, thereby preventing belt skew defects on fused copies.
