Abstract
A printer includes a plurality of a plurality of printheads and a plurality of rolls positioned opposite the printheads along a media path in the printer. Print media contact and move over the rolls as the printheads eject ink onto the print media moving along the media path. A controller is configured to generate a signal to operate a printhead with reference to an angular position of a roll positioned opposite to the printhead that receives the signal to compensate for flight time errors due to backer roll eccentricity.
