Abstract
A printing apparatus has a series of inkjet print heads spaced from one another in a transport direction. A continuous belt driven around a roller system is used to feed sheet media successively to the print heads so that a partial image printed by one print head is overprinted at a subsequent print head with registration of the partial images. A sheet medium is caused to become electrostatically tacked to the belt by passing the sheet past a charging device. Movement of the belt is tracked by a tracking sub-system and operation of the print heads is coordinated with the tracked belt movement to achieve precise registration of the partial images.
