Abstract:
A bidirectional media supporting system includes a first and second rollers configured to rotate to feed media in forward and reverse feed modes; a first clutch bearing set, and a second clutch bearing set configured to engage with the first clutch bearing set; and a gear transmission assembly configured to transfer a driving force from the first roller to the second roller. A method for reversing direction of printing media includes advancing media while maintaining a rotational speed of a platen roller assembly above that of a feeding roller assembly; receiving a signal to reverse the direction of advancing media; and adjusting operation by reversing a direction of rotation of a transmission gear coupled to the feeding and platen roller assemblies, and by rotating the roller assemblies in an opposite direction, while maintaining the rotational speed of the platen roller assembly below that of the feeding roller assembly.
