Abstract
An escort belt facilitates removal of particulate from a print zone in an ink printing machine while maintaining proper registration of printing media in the print zone. The escort belt includes an endless belt having a width between a first and a second edge of the escort belt that is greater than a media sheet carried by the escort belt, a first plurality of apertures arranged in a longitudinal line proximate one of the belt edges of the escort belt, and a second plurality of apertures distributed between the first plurality of apertures and the other edge of the escort belt, the apertures of the first plurality having a shape different from that of the second plurality of apertures and the apertures of the first aperture plurality being positioned so the apertures are only partially covered by edges of the media being held to the escort belt by a vacuum source applied to the first and the second pluralities.
