A method of performing a user related operation includes, with an optical reader, reading an encoded on-line address being displayed on a display of a pocket-sized card to be carried by a user; decoding the encoded on-line address; requesting access to remotely stored data using the on-line address, the remotely stored data being related to the user; and, upon the requested access being granted, loading the remotely stored data.

Printers, methods, and apparatus to reduce aerosol are disclosed. An example apparatus to reduce aerosol includes a print head to generate droplets and aerosol, and to direct the droplets toward a print substrate, a first corona wire to generate first ions having a first electrical polarity to direct the aerosol toward the print substrate, and a second corona wire to generate second ions to direct the aerosol toward the print substrate, wherein the second ions have a second electrical polarity that is opposite the first electrical polarity.

A cleaning system usable with an image forming apparatus, which includes an intermediate transfer member having an image transfer blanket, includes a cleaning unit including a cleaner roller having at least one channel to transport fluid therein and a cleaner receiving surface to receive a cleaner layer, and a control unit including a temperature control module to control transportation of the fluid through the at least one channel to regulate a temperature of the cleaner roller, with the cleaner layer formed on the cleaner receiving surface to remove surface contaminants from the image transfer blanket.

Systems and associated methods of printing using ink-jet technology and offset printing capabilities are provided. The method can comprise jetting an ink onto a printing blanket, where the ink comprises a carrier and a pigment colorant, and where the carrier substantially free of polymers. Additional steps include developing the ink to create a print image on the printing blanket; applying a layer of wetting fluid to a surface of a print medium, where the surface includes a coating comprising a polymer; heating the surface to a print-receptive temperature that is lower than the softening temperature of the polymer, causing softening of the polymer; and transferring the print image from the printing blanket to the surface.
摘要:
An ink composition has controlled conductivity, and a digital printing system and a method of printing an ink employ an offset inkjet printing platform. The ink composition includes pigment particles dispersed in an oil-based dielectric carrier fluid with an oil-soluble dispersant. A concentration of dispersant is a fraction of a concentration of the pigment particles sufficient to render an electrical conductivity of the ink composition less than 100 pico Siemens per centimeter (pS/cm). The printing system includes an ink having an electrical conductivity less than or equal to about 300 pS/cm, an inkjet print head, a transfer medium, a developer, a remover and an image transferer. In the method of printing, the ink is nonelectrostatically jetted to the transfer medium, and developed into a fixed image. A portion of a supernatant is removed from the fixed image, and the fixed image is transferred to a media substrate.

An imaging device can include an imaging drum to support a carrier fluid. A roller can remove a portion of the carrier fluid from the imaging drum. A fluid container can collect the carrier fluid from the roller. A fluid remover on the container can be used to remove the carrier fluid from the roller.

A printing assembly includes a pressure control tank and a printhead assembly. The printhead assembly is in fluid communication with the pressure control tank while the printhead assembly and the pressure control tank are selectively rotatable into a plurality of different positions relative to one another.

Techniques for protecting imaging access of electronic paper are described herein. For example, an electronic paper device with protected imaging access includes a substrate, an e-paper surface disposed on the substrate, a removable cover to prevent alteration of the e-paper surface when the cover is disposed over the e-paper surface, and a reversible locking mechanism engaging with the cover to secure the cover in place over the e-paper surface. A method for secure writing to e-paper is also provided.
