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.
Claims9
A method of operating a digital printer, the printer including a photosensor disposed in a substantially fixed location, comprising:
- deciding whether to print a machine readable code on a first sheet and at least one test patch on a second sheet, or to print the machine readable code and the at least one test patch on a one sheet;
- moving the sheet having the machine readable code at a substantially constant velocity past the photosensor following printing;
- and
- in response to the photosensor detecting the machine readable code, initiating the photosensor reading the test patch.
