Claim:
In a 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 pair of rollers, comprising: a first driven roller, for transporting the medium, having a precision diameter and capable of rotating about a first axis in first and second opposing directions; and a first non-driven roller having an axis of rotation that has a first horizontal offset and a first vertical offset from an axis of rotation of said first driven roller, wherein said first horizontal offset is in a direction in which the medium exits from the system; a second pair of rollers, comprising: a second driven roller, for transporting the medium, having a precision diameter and capable of rotating about a second axis in first and second opposing directions, in concert with said first driven roller, the speed at the diameter of said first and second driven rollers being substantially the same, and wherein said first driven roller receives the medium prior to said second driven roller; and a second non-driven roller having an axis of rotation that has a second horizontal offset and second vertical offset from an axis of rotation of said second driven roller, wherein said second horizontal offset is in a direction in which the medium is received in the system; and wherein at least one of said first driven and non-driven rollers and said second driven and non-driven rollers contact the medium while the image is recorded on the medium.
