摘要:
A vacuum transport belt for use in a multipass, multicolor raster printer has a vacuum attach means for providing a strong hold down vacuum force in the direction of paper travel for complete registration of a recording material with respect to a writing head and toner system. The vacuum attach means comprises a thin metal strip bonded to a transport belt such that the surface of the strip is substantially flush with the surface of the belt. A strong hold down vacuum is conducted through channels underneath the bonded strip to a series of closely clustered apertures which form a vacuum contact region on the strip. The force of the vacuum applied at the contact region and the substantially flush contact between the surface of the strip and the transport belt tightly seals the entire surface of the recording material to the transport belt, thereby registering the recording material precisely to the transport belt in an invariant desired alignment with a writing head and toner system.
