DISTURBANCE ISOLATION IN A BELT RECEPTOR OF A COLOR PRINTER

摘要

A belt receptor module for a color printer isolates disturbances such as impulsive and high-frequency force disturbances caused by entrance of a recording medium into a transfer nip of a transfer station. The belt receptor module includes a belt receptor positioned about a plurality of spaced rollers. A transfer station is located adjacent an area of the belt receptor. A tension roller is located adjacent the belt receptor on either side of the transfer station. The tension rollers each articulate about an appropriate axis to enable the belt receptor to enter a subsequent roller at an angle of approximately 90.degree. to its axis without generating lateral forces. Each tension roller is movable along a different line to create a tension level therein, each tension level being different from the other tension level. The tension levels generated by the tension rollers do not substantially change with the position of said rollers and, thus, providerelief from the impulsive and high-frequency force disturbance caused by the entrance of a recording medium into a transfer nip of the transfer station. Theisolation of the disturbance enables proper registration of the color separations while avoiding motion-induced artifacts.
