A method for detecting accuracy of media advancement is disclosed. A first set of nozzles of a printhead imprints a first swath of prints on a media sheet. After the media sheet is advanced by a predetermined distance, a second set of nozzles located in front of the first set of nozzles in the direction of the media advancement imprints a second swath of prints on the media sheet. The degree of the alignment of these two swaths of prints then serves as an accuracy factor of the media advancement and the accuracy factor can then be ascertained.
