ABSTRACT:
A device that addresses the problem of substrate distortion created by a fuser nip being transmitted back to a transfer nip includes a post transfer corrugator that introduces a non-image side protrusion in the substrate path between the transfer zone and the fuser zone. The post transfer corrugator forces the substrate to flatten out any distortion caused by the fuser
ip and prevents this distortion from entering the transfer zone. The corrugator also supports the substrate so as to increase the wrap angle of the substrate around an electrostatic member.
