Star Wheel with Adjustable Directional Biaser

A print media feed system in an inkjet printer, said system comprising:

• a feed roll;
• a first star wheel mounted opposing the feed roll forming a nip therebetween for receiving and feeding a sheet of media;
• an adjustable directional biaser coupled to the first star wheel;
• and
• a controller communicatively coupled to the biaser, the controller being configured to adjust the biaser to provide in a first position a biasing force to move the first star wheel toward the feed roll and in a second position to provide a biasing force to move the first star wheel away from the feed roll with the biasing force changing magnitude and direction as the directional biaser moves between the first and second positions.

A print media feed system in an inkjet printer, said system comprising:

• a feed roll;
• a first star wheel mounted opposing the feed roll forming a nip therebetween for receiving a sheet of media;
• a first lever having a first end pivotally mounted in the inkjet printer and a second end rotatably coupled to the star wheel;
• a first cam having an elliptical shape operably coupleable to a motor;
• a first biasing member holding the first lever against the first cam;
• and
• a controller communicatively coupled to the motor, the controller being configured to adjust the angular position of the motor to adjust the angular position of the cam to provide one of a plurality of biasing forces to the first star wheel as the angular position of the first cam changes, each of the plurality of biasing forces having a unique magnitude, a unique direction, or a unique magnitude and direction.
