Patent abstract
A method of operating a digital printer comprises printing a machine-readable code and at least one test patch on at least one sheet. The photosensor detects the machine readable code on the moving sheet, and, in response to the detecting, initiates the photosensor reading the test patch on the moving sheet. The test patches can be distributed over many sheets, depending on the nature of the desired test routine and the type of sheet that has recently been output by the printer.
