Zusammenfassung:An ink-jet apparatus is disclosed having a vacuum type print media transport subsystem for moving the print media through a printing zone. A transport belt is provided with an array of perforations such that vacuum flow is restricted. The perforations only pass vacuum induced airflow through the belt when over vacuum ported platen regions. In an alternative embodiment, belt lifting is controlled and substantially eliminated via vacuum ports associated with non-perforated regions of the transport belt.
