Claim:
A media sheet transport comprising: a belt for supporting the media thereon, the belt being operably connected to a drive mechanism for moving the belt in a process direction past an image marking unit, the belt having a plurality of openings therein; a vacuum plenum having a surface disposed below the belt and being operably connected to a vacuum source, the vacuum plenum being adapted to applying a negative pressure to the media for holding the media to the belt; and an electrostatic hold down apparatus including a first tacking roller spaced in a cross-process direction from a second tacking roller, the first and second tacking rollers being engagable with the belt, the first tacking roller being disposed to engage the inboard edge of the media and the second tacking roller being disposed to engage the outboard edge of the media, the first and second tacking rollers depositing an electrostatic charge to the edges of the media for electrostatically securing the inboard and outboard edges of the media to the belt, and wherein a position of the first and second tacking rollers is adjustable in the cross-process direction and the first and second tacking rollers are operably connected to an adjustment mechanism for adjusting their position in the cross-process direction responsive to the width of the media.
