Xerox Corporation is an American multinational document management corporation that produces and sells a range of color and black-and-white printers, multifunction systems, photocopiers, digital production printing presses, and related consulting services and supplies. Xerox is headquartered in Norwalk, Connecticut , though its largest population of employees is based around Rochester, New York, the area in which the company was founded. On September 28, 2009, Xerox announced the intended acquisition of Affiliated Computer Services for $6.4 billion. The deal closed on February 8, 2010. As a large developed company, it is consistently placed in the list of Fortune 500 companies.Researchers at Xerox and its Palo Alto Research Center invented several important elements of personal computing, such as the desktop metaphor GUI, the computer mouse and desktop computing. These features were frowned upon by the then board of directors, who ordered the Xerox engineers to share them with Apple technicians. The features were taken on by Apple and, later, Microsoft. Partly thanks to these features, these two firms would then go on to duopolize the personal computing world. Wikipedia.

Methods for lubricating an imaging member include applying lubricant-containing capsules to the surface of the imaging member via a non-contact applicator. The capsules are applied upstream of a cleaning blade after image transfer to another substrate, such that the cleaning blade ruptures the capsules, thereby releasing the lubricant contained therein.


A method for forming an ink jet printhead comprises processing an epoxy adhesive such that negative effects from physical contact with particular inks are reduced or eliminated. Conventional adhesives processed using conventional techniques are known to gain weight and squeeze out when exposed to certain inks such as ultraviolet inks, solid inks, and aqueous inks. An embodiment of the present teachings can include processing of a particular adhesive such that the resulting epoxy adhesive is suitable for printhead applications.

A printhead includes an aperture plate having an array of nozzles therethrough. The printhead further includes an array of jets fluidly connected to an ink supply chamber, each jet comprising a body chamber having a length:width ratio of at least 3:1. The body chamber comprises a first end, and a second end opposite the first end, the first end and the second end defining a height. Ink flows into body chamber through an inlet, and an outlet on the first end is fluidly connected to a nozzle. A diaphragm is present adjacent the second end of each body chamber in the array of jets. The body chambers are angled relative to a row of nozzles.


An embodiment of the present disclosure is directed to a sacrificial coating composition for an image transfer member in an aqueous ink imaging system. The coating composition is made from ingredients comprising: a latex comprising polymer particles dispersed in a continuous liquid phase; at least one hygroscopic material; at least one oil-in-water emulsion; and at least one surfactant.


A composite includes a sulfonated polyester matrix and a plurality of silver nanoparticles dispersed within the matrix. Methods to make these composites include heating a sulfonated polyester resin in an organic-free solvent adding a solution of silver (I) ion to the heated resin in water to form a mixture, adding a solution of a reducing agent to the mixture, thereby forming an emulsion of composite particles including a sulfonated polyester matrix and a plurality of silver nanoparticles disposed within the sulfonated polyester matrix. Various articles can be manufactured from such composites.


A maintenance method for a three-dimensional printer includes operating a platform to move along a second track past a first position where the second track is coupled to a first track, and along the first track in a process direction to a position opposite an ejector head positioned opposite the first track. The method operates the platform to (1) perform an operation on the ejector head positioned opposite the first track, (2) move the platform along the first track to a second position that is past the ejector head in the process direction, and (3) operates a switch to selectively couple the first track to the second track at the second position. The method also operates the platform to move past the second position to enable the platform to return to the second track.


Disclosed herein include toner compositions with toner particles having a core-shell type structure, where the core comprises a first resin comprising a styrene-acrylate copolymer and an amorphous polyester resin, and the shell comprises a second resin comprising beta-carboxyethyl acrylate (b-CEA) in an amount of from about 0.05 pph to about 2.5 pph by weight of the second resin.


A method of digitally printing a solder mask. The method includes providing a solder mask ink composition including: 1) a resin and 2) a solvent in an amount of at least 20% by weight relative to the total weight of the solder mask ink composition. The composition has a viscosity that is less than 1000 cps at a shear rate of 10 s^(1 )and a temperature of 25 C. An aerosol stream is generated from the solder mask ink composition with a pneumatic atomizer using an atomization gas. The aerosol stream is directed through a nozzle and focused using a sheath gas onto a substrate while changing the position of the nozzle with respect to the substrate to selectively deposit a solder mask pattern. The solder mask pattern is cured.


This disclosure is directed to functionalized carbon black material that may be particularly usable for as a filler material to a number of beneficial uses, particularly in image forming devices. The disclosed functionalized carbon black material compositions include hydrophobic carbon black particles surface passivated via the use of an A/B-block copolymer where the A/B block contains a pentafluorostyrene-maleimide alternating polymer and the B block contains pure pentafluorostyrene. The A/B portion allows for the polymer to adsorb onto the carbon black while the b-block acts as the stabilizer in fluorinated systems. Fine dispersions result from the addition of poly (pentafluorostyrene/Maleimide-b-pentafluorostyrene) or P(PFS/MI-b-PFS) passivated carbon black to fluorinated polymers, enhancing the physical and mechanical properties. The disclosed surface passivated carbon black particles are particularly usable for improving operational characteristics of fluorosilocone-based reimageable surface layers of imaging members employed in variable data digital lithographic image forming devices.


A method of making a sacrificial coating composition is disclosed. The method comprises emulsifying an oil with surfactant and water to form an oil-in-water emulsion; and combining ingredients comprising (i) at least one polymer, (ii) at least one hygroscopic material, (iii) the oil-in water emulsion and (iv) water to produce the sacrificial coating composition. The at least one polymer is selected from the group consisting of a hydrophilic polymer, a latex comprising polymer particles dispersed in a continuous liquid phase, or mixtures thereof.
