Also disclosed herein is a substrate on which is electrostatically printed a conductive trace, wherein the trace comprises a resin and an elongate conductive species. Further disclosed herein is a method of electrophotographic printing an electrostatic ink composition comprising a resin and an elongate conductive species.
摘要:
A system and method to compensate for ghost appearances on a print due to a previous job, the method comprising defining areas in which ghosting is expected or detected and recording the image on a photoreceptor by selectively changing the parameters of the system as a function of position, to compensate for the effects of ghosting in ex-image and ex-nonimage areas.

An embossing apparatus includes an embossing die that includes a printed relief pattern made up of multiple layers of a deposited material. A resilient surface presses media against the embossing die such that embossed features corresponding to the embossing die are formed in the media. A method for embossing media includes forming an embossing die by depositing multiple layers of ink on a impression layer to form a relief pattern and pressing media against the embossing die to transfer the relief image to the media.

A method and apparatus for re-circulating a carrier in a printer is disclosed. The re-circulating system comprises a controller, a print head, a variable speed fan coupled to an air passageway and a condenser. The controller determines a liquid amount of carrier to be place on a page during a print operation. The controller adjusts the variable speed fan dependent on the amount of liquid carrier determined to be placed onto the page.

A marking agent concentration method includes concentrating the marking agent by removing at least some liquid carrier between particles without substantially removing retained liquid carrier within the particles and without substantially modifying the particle structure, which is supported by the retained liquid carrier. The concentrated marking agent is supplied to distributors or end users of liquid marking agent. A concentrated marking agent includes solid clumps of agglomerated particles and a liquid carrier retained within the particles' individual structure. The clumps exhibit a median size greater than 90 μm. The concentrated marking agent exhibiting a solids content of from 40 wt % to less than 90 wt %. A hard imaging method includes combining a concentrated marking agent with additional liquid carrier, applying a shear force, dispersing particles from clumps, forming a liquid marking agent, and forming a hard image using the liquid marking agent.
摘要:
A method of treating a photoconductor for enhancing crack resistance when it comes into contact with a liquid toner comprises bending a photoconductor sheet having a length and a width to a tube having an outer diameter and a length corresponding to the width of the photoconductor sheet with the photoconductive layer facing outward. The tube of the photoconductor sheet is then inserted into a cylinder having an inner diameter greater than the outer diameter of the tube and a length of at least the length of the tube of the photoconductor sheet. The treatment of the tube of the photoconductor sheet in the cylinder takes place by maintaining it in the cylinder at a temperature of from about room temperature to an elevated temperature. The tube of the photoconductor sheet is removed from the cylinder while it is at about room temperature.
