Abstract
A method of determining calibration values for a media advance system of a page wide array printing device is described. A test pattern is printed on a calibration medium which advances along a media axis through the printing device. The test pattern comprises a plurality of test marks. The test pattern is scanned along a scan axis using a sensor and the calibration medium is advanced along the media axis through the printing device. The dimensions of the scanned test marks are analyzed, and calibration values are determined from the analyzed dimensions of the test marks. The scan axis is orthogonal to the media axis.
