Abstract
In accordance with the preferred embodiment of the invention, a cam-operated idler roller assembly maintains tension on a computer printer generated form as it advances through the print station of a computer printer. This invention provides a nip station that disengages on a print medium reversal to allow the form to be run in a reverse direction through the print station by means of a cam design that disengages the idler roller assembly from the drive roller. The cam design further allows the idler roller assembly to reengage on forward print media movement to reestablish tension in the printing station.
