Abstract
A prefuser vacuum transport apparatus that increases the latitude of sheet acquisition includes at least one perforated belt entrained around a vacuum plenum to provide a limited drive force on sheets being driven by the vacuum transport apparatus. The vacuum plenum includes a vacuum port surface having a profile that is contoured to follow the profile of the stiffest sheet to be transported with the maximum specified curl. The belt follows the port surface contour.
