Printer having skewed transfix roller to reduce torque disturbances

Abstract

An inkjet offset printer includes an imaging drum and a transfix roller skewed with respect to and defining a continuously applied or an uninterrupted nip with the imaging drum to reduce torque disturbances and media wrinkling issues. Acoustic and physical disturbances resulting from a sheet of recording media entering and leaving the nip are reduced or eliminated.

Description

technical field [0001] The present disclosure relates generally to solid ink flatbed printers, and more particularly to transfix rollers that are skewed relative to an imaging drum and together define a continuously applied or uninterrupted nip to reduce torque interference. Background technique [0002] A typical inkjet printer uses one or more printheads, each containing an array of individual nozzles, during printing ink droplets are ejected by the inkjet through the nozzles through open gaps to an image receiving member having an image receiving surface to form an ink image. The image receiving surface may be the surface of a continuous web of recording media, the surface of a series of sheets of media, or the surface of an image receiving member, which may be an imaging drum, a rotating print drum, or an endless belt. In an inkjet printhead, individual piezoelectric, thermal or acoustic actuators generate a mechanical force to eject ink through holes, often called noz...
