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.

Calibrating a media advance system of a page wide array printing device

An apparatus includes a plurality of transport elements to cause a movement of a medium received at a media input in a movement direction towards a media output, wherein the plurality of transport elements are arranged spaced apart from each other in the direction transverse to the movement direction of the medium, wherein the plurality of transport elements include a first transport element to be moved with a first velocity, a second transport element to be moved with a second velocity, and a third transport element to be moved with a third velocity, the second transport element arranged between the first and third transport elements, and wherein the first and third velocities are greater than the second velocity.
