Abstract

A hardcopy apparatus comprising a media holddown unit, having a platen (400), and a vacuum source (700) for generating negative pressure on a medium positioned on said platen (400) to keep it flat on said platen (400), the unit comprises at least two vacuum chambers (382, 383, 690, 691, 692, 693), both in air communication with the vacuum source. Each of said vacuum chambers (382, 383, 690, 691, 692, 693) can apply a negative pressure to a different portion of the medium positioned on a corresponding different region of the platen. A method for holding down a medium when placed on said platen. First the vacuum source is placed into independent air communication with a number of distinct regions of the platen, then the medium is positioned to cover one or more regions of the platen, and finally a negative pressure is applied to the back of the medium via the independent air communication.
