Abstract (en)
A scanning inkjet printing assembly comprises a driving roller for moving the recording medium. Irregularities in the surface of the driving roller affect the accuracy for positioning the recording medium, and thereby the image quality. Width dependent irregularities in the outer surface of the driving roller can be corrected by a sub-carriage moveably supported on a carriage which scans across the recording medium for printing consecutive swath. The sub-carriage is moveable in the transport direction of the recording medium with respect to the carriage. From stored cyclic deviation data a control unit appropriately controls the movement of the sub-carriage in the transport direction as the carriage scans over the recording medium, thereby correcting for the irregularities in the surface of the driving roller.
