<P>PROBLEM TO BE SOLVED: To provide a sheet transport capable of maintaining sheets in flat orientation without excessively adding costs or complexity. <P>SOLUTION: A belt 18 is operably connected to a drive mechanism for moving the belt in a process direction past an image marking unit. The belt has a plurality of openings 30 therein. A vacuum plenum has a surface disposed below the belt and is operably connected to a vacuum source. The vacuum plenum is adapted to applying a negative pressure to the media 14. An electrostatic hold down apparatus 32 includes a first tacking roller 36 spaced in a cross-process direction from a second tacking roller 34. The first and second tacking rollers are engagable with the belt. The first tacking roller is disposed to engage the inboard edge of the media, and the second tacking roller is disposed to engage the outboard edge of the media. The first and second tacking rollers impart an electrostatic charge to the edges of the media for electrostatically securing the inboard and outboard edges of the media to the belt. <P>COPYRIGHT: (C)2013,JPO&INPIT |
