Embodiment Construction

[0017] Figure 5 A high speed phase change ink image producing machine or printer 10 is shown. As shown, printer 10 includes a frame 11 that directly or indirectly supports operating subsystems and components, as described below. The printer 10 includes an image receiving member 12, which is shown in the form of a drum, but may also include a supporting endless belt. The image receiving member 12 has an imaging surface 14 movable in a direction 16 and on which a phase change ink image is formed. A transfix roller 19 , rotatable in direction 17 , is loaded against surface 14 of drum 12 to form a transfix nip 18 in which the ink image formed on surface 14 is transferred to a recording medium 49 .

[0018] The high speed phase change ink printer 10 also includes a phase change ink delivery subsystem 20 having at least one source 22 of one color phase change ink in solid form. Because the phase change ink printer 10 is a multicolor image producing machine, the ink delivery syst...

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...
