Abstract:
1. In a platesetting system that receives a recording medium and records an image on the received medium as the medium is transported through the system, a drive assembly for transporting the medium comprising: a first driven roller having a precision diameter; a second driven roller having a precision diameter; a first non-driven roller having an outer surface substantially centered in a vertical position about said first driven roller; a second non-driven roller having an outer surface substantially centered in a vertical position about said second driven roller; a first motor operationally connected to said first driven roller; a second motor operationally connected to said second driven roller; and a controller receiving as input the speed of an outer surface of said first and second driven rollers and optionally adjusting the speed of at least one of said first and second motors to provide a substantially same speed at the outer surface of said first and second rollers for transporting the medium at he substantially same speed in first and second opposing directions as determined by simultaneous counterclockwise and clockwise rotation, respectively, of each of said first and second driven rollers.
