Attorney, Agent or FirmInternational ClassB41J 11/00 (20060101)AbstractA constant velocity transport (CVT) is disclosed for use with a marking apparatus such as an ink jet printing system. The transport utilizes vacuum hold-down plenums to convey sheets to and away from the printing zone of the marking apparatus and a sheet-attracting vacuum arrangement, between the two plenums for drawing the sheet to a guide surface as the sheet moves through the printing zone. The sheet-attracting action is effective just at the point marking is effective upon the sheet thereby insuring the precise location of the sheet for printing. | |
