Clutch bearing to keep media tension for better sensing accuracy

A bidirectional media supporting system, comprising:

• a first roller configured to rotate to feed media in a forward feed mode and in a reverse feed mode;
• a second roller positioned parallel to the first roller, and configured to rotate in the same direction as the first roller;
• a first clutch bearing set operably coupled to the second roller;
• a second clutch bearing set operably coupled to the second roller, and configured to engage with the first clutch bearing set;
• and
• a gear transmission assembly, operably coupled to the first roller with a belt pulley assembly, and directly coupled to the second roller with the first clutch bearing set, and configured to transfer a driving force from the first roller to the second roller, the second clutch bearing set on the same shaft as the second roller.

A method for reversing direction of printing media, comprising:

• advancing media in a first direction, with a feeding roller assembly and a platen roller assembly, by rotating the feeding roller assembly and the platen roller assembly in the first direction and maintaining a rotational speed of the platen roller assembly above a rotational speed of the feeding roller assembly;
• receiving a signal to reverse the first direction of advancing media;
• and
• adjusting operation of the feeding roller assembly and the platen roller assembly by reversing a direction of rotation of a transmission gear assembly operably coupled to the feeding roller assembly and the platen roller assembly, and by rotating the feeding roller assembly and the platen roller assembly in a second direction opposite the first direction and maintaining the rotational speed of the platen roller assembly below the rotational speed of the feeding roller assembly.
