摘要:
A vacuum control assembly for use in an image production device is provided. The assembly has a plenum, a perforated plate, a plurality of valve assemblies, and a controller. Each valve assembly has a rotating valve having a vacuum passage, and a chamber body having a plurality of chambers. Each valve is rotatable between a first position that fluidly connects the vacuum passage with at least one of the chambers to complete a fluid path between the plenum and the perforated plate, and a second position at which the vacuum passage connects the plenum with none of the chambers. The controller controls the plurality of valve assemblies to provide vacuum to a first predetermined portion of the perforated plate while also providing no vacuum to a second predetermined portion of the perforated plate.
