Patent ID: 6873821

Claim:
A sheet transport system for transporting print media sheets in a part of a printer sheet feeding path, said sheet transport system having at least a plurality of sheet feeding rollers spaced apart along said sheet feeding path, each said sheet feeding roller having a substantially uniform diameter extending transversely fully across said sheet feeding path and uniformly exposed to direct contact with said print media sheets in said printer sheet feeding path, wherein there is additionally provided in said sheet transport system a vacuum manifold underlying said plurality of sheet feeding rollers and at least one sheet transport baffle and airflow slot between each of said plurality of sheet feeding rollers, said airflow slots extending transversely across said sheet feeding path, said airflow slots pneumatically communicating with said underlying vacuum manifold to provide a vacuum force on said sheets in said sheet transport system adjacent said plurality of sheet feeding rollers via said airflow slots extending transversely across said sheet feeding path to hold said print media sheets against said sheet feeding rollers to provide substantially uniform transverse temperature control over said print media sheets being fed by said sheet transport system.
