ABSTRACT:
A sheet transport system with improved sheet contacting thermal uniformity for transporting thermally sensitive imaged print media sheets in a sheet path of a printer, in which multiple sheet feeding rollers are spaced along sheet feeding path, with each said sheet feeding roller having a substantially uniform diameter extending transversely fully across the sheet feeding path for uniform sheet contact, with uniform baffles between the rollers also extending transversely fully across the sheet feeding path, for uniform sheet contact, and with vacuum sheet holddown provided by airflow slots on oppose sides of each sheet feeding roller extending transversely across the sheet feeding path.
