摘要： An apparatus and method for cleaning an image transfer surface in an image transfer device. The cleaning apparatus includes a first cleaning station and a second cleaning station positioned to consecutively clean the image transfer surface. The first and second cleaning stations apply cleaning fluid to the image transfer surface and remove cleaning fluid with residual material from the image transfer surface. A first tank supplies cleaning fluid to, and receives cleaning fluid with residual material from, the first cleaning station. A second tank supplies cleaning fluid to, and receives cleaning fluid with residual material from, the second cleaning station. The second tank also supplies cleaning fluid to the first tank.

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.

摘要： Hard imaging devices and methods are described. According to one arrangement, a hard imaging device includes a media transport system configured to move media along a media path and a print device adjacent to the media path and configured to eject a plurality of droplets of a liquid marking agent in a direction towards the media moving along the media path to form hard images using the media. The ejection of the droplets of the liquid marking agent by the print device creates satellites of the liquid marking agent suspended in air in a region adjacent to the print device and the media. The device also includes a satellite removal system in one arrangement to remove the satellites from the air in the region adjacent to the print device and the media.
