Apparatus and method of making an ink-jet-ink-derived material image on a receiver. An ink jet device is used to form a coagulable ink image on a member, the ink image including a coagulable marking ink and a non-marking ink. Each smallest resolved imaging area of the ink image includes a predetermined mixed volume of the coagulable marking ink and the non-marking ink, the predetermined mixed volume being coagulable. Coagulates are formed within the coagulable ink image, and excess liquid is removed from the coagulates to form an ink-jet-ink-derived material image. The ink-jet-ink-derived image is transferred from the operational surface of the intermediate member to another member, which another member may be a receiver member, a drum or a web.

Imaging using a coagulable ink on an intermediate member

An air quality management apparatus for use in a modular electrostatographic color printer. For air quality management a non-air-conditioned open-loop portion is provided for managing quality of air in a first interior volume, and an air-conditioned recirculation portion is provided for managing quality of air in a second interior volume. The first interior volume includes a fusing station for fusing color images on receiver members. The second interior volume includes a number of tandemly arranged image-forming modules, as well as an auxiliary chamber associated with, yet isolated from, each module, such that air-conditioned air flowing through each module does not mix with air-conditioned air supplied to the modules and to devices within the modules. The second interior volume is differentiated from the first interior volume by at least one separating member. The air-conditioning device is for controlling temperature and relative humidity of air included in the second interior volume.

Air quality management apparatus for an electrostatographic printer

Apparatus and method of making an ink-jet-ink-derived material image on a receiver. An ink jet device is used to form a coagulable ink image on an intermediate member. Coagulates within the coagulable ink image are formed, and excess liquid is removed from the coagulates so as to form an ink-jet-ink-derived material image. The ink-jet-ink-derived image from the operational surface of the intermediate member is transferred to another member, which another member may be a receiver member, a drum or a web.

Ink jet imaging via coagulation on an intermediate member

Apparatus and method of making an ink-jet-ink-derived material image on a receiver. An ink jet device is used to form a colloidal ink image on a member. The ink for use in the ink jet device includes an aqueous-based colloidal dispersion of particles and a nonaqueous colloidal dispersion of particles. The ink for use in the ink jet device includes an aqueous-based colloidal dispersion of particles, a nonaqueous colloidal dispersion of particles. The particles of the colloidal ink image are caused to become concentrated adjacent an operational surface of the member. Excess liquid is removed from the particles so as to form an inkjet-ink-derived material image. The ink-jet-ink-derived image is then transferred from the operational surface of the intermediate member to another member, which another member may be a receiver member, a drum or a web.

A conformable roller for use in a fusing station of an electrostatographic machine, the fusing station being provided with a pressure roller and a fuser roller for fusing a toner image on a receiver, the fuser roller made from a plurality of layers surrounding an axis of rotation, the conformable roller comprising a rigid cylindrically symmetric core member; a flexible replaceable removable compliant sleeve member in the form of a tubular belt surrounding and nonadhesively intimately contacting the core member; and the fusing station including an external heat source for the fuser roller, at least one of the plurality of layers being thermally resistive.

Sleeved rollers for use in a fusing station employing an externally heated fuser roller

A method and apparatus for controlling image defects associated with overdrive or underdrive, and variations thereof, in an electrostatographic machine. A speed modifying force is transmitted to a conformable member that deforms in a nip, thereby inducing strains in the surface of the member at the nip which cancel or controllably reduce the strains caused by engagement in the nip. The speed modifying force may be an externally applied drag force or torque, and may be applied using an open loop or a feedback system including an electromagnetic brake, a motor, etc. The speed modifying force may be applied to a conformable member forming the nip through a redundant linkage of the system that employs gears or other suitable mechanisms.

Method and apparatus for using a conformable member in a frictional drive

Controlling image defects related to transfer or fusing of toner images in an electrostatographic machine, wherein engagement between an operational surface of a toner image bearing member or fusing member and an operational surface of another member forming a nip is adjusted using an engagement adjustment device in order to reduce or eliminate image defects relating to an overdrive or underdrive associated with the nip. The engagement adjustment device provides a preselected amount of overdrive or underdrive between a toner image bearing member or fusing member and a receiver member, which preselected amount includes zero.
