In a tightly integrated parallel printing architecture having at least a
first print engine and a second print engine, the first print engine and
a second print engine includes a first fuser system having a first fusing
member for fusing marking particles on the substrate and second fuser
system having a second fusing member for fusing marking particles on the
substrate, including: a calibration system for maintaining uniform gloss
characteristics between printed images generated by the first fusing
system and the second fusing system, the calibration system including
sensor for sensing a gloss value indicative of the gloss of the fused
marking particles on the substrate.
