Abstract
A print media feed system in a inkjet printer, the system has a media feed roll, a star wheel mounted opposing the roll, an adjustable biaser coupled to the star wheel, and a controller coupled to the biaser. The controller varies a magnitude, a direction or a magnitude and direction of a biasing force applied to the star wheel by the biaser. In one form, the biaser comprises a motor driven cam that varies the angular position of a pivotable lever having a star wheel rotatably attached on one end. In another form, a rack and pinion gear assembly is used to vary the biasing force with a star wheel rotatably attached to the rack. In a further form, a solenoid is used to vary the basing force applied to the lever or applied to a star wheel rotatably attached to the end of the shaft of a solenoid.
