An electrophotographic process which comprises the generation of a latent image; developing the image with a toner composition comprised of resin particles, magnetite particles, and a polymeric fluorocarbon; and subsequently providing the developed image with magnetic ink characters thereon to a reader/sorter device whereby toner offsetting and image smearing is avoided or minimized in said device.

Toner compositions and processes thereof

An ink handling system in an ink jet printer. In accordance with the invention an ink handling system is constructed including two ink processing loops. A first relatively low-volume, high pressure ink handling loop or circuit routes ink to an ink jet printhead for directing one or more columns of ink toward a printing medium. A second relatively high volume yet low-pressure loop or circuit routes ink through a number of processing stations which, for example, include ink de-aeration, filtration, and temperature control. The bulk of the processing is performed in this second loop, yet limited processing steps are also performed in the high-pressure, low-volume circuit which directs ink to the printhead. As ink is lost due to evaporation and/or printing on the print medium, the ink is replenished via an ink source which is coupleable to a main ink tank forming a portion of the high-volume ink handling loop.

Ink jet ink handling system

A contact fuser assembly for use in electrostatic reproducing apparatus including a heated fuser roll structure cooperating with a backup roll to form a nip through which copy sheets having toner images thereon move with the toner images contacting the heated fuser roll structure. The fuser assembly is characterized by the provision of a cleaning arrangement comprising a roll having a tacky surface which is adapted to contact the fuser roll structure to thereby remove contaminants therefrom. The cleaning arrangement is further characterized by the provision of means for rejuvenating the tacky surface of the cleaning roll wherein polymer material is applied to the cleaning roll and is tacky at the operating temperature of the fuser apparatus.
