Multi-function printing (mfp) device calibration

A multifunction printing (MFP) device comprising:

• a scanning device;
• a background of the scanning device comprising a repeating series of alternating darker tones and lighter tones perpendicular to a scan direction of the scanning device;
• a memory device comprising a calibration target image stored thereon;
• a printing device to print the calibration target image on a plurality of print media from a corresponding number of print medium sources;
• and
• a calibration engine to, for each of the plurality of print media, calculate a calibration target error based on a number of fiducials within the calibration target image and a number of scan measurements defined by the background.

A computer program product for calibrating a multi-function printing (MFP) device, the computer program product comprising:

• a computer readable storage medium comprising computer usable program code embodied therewith, the computer usable program code to, when executed by a processor:
• print a calibration target image on a first side of a print medium from at least one print medium source with a printing device of the MFP device, the calibration target image comprising at least one fiducial;
• scan a first side of the print medium comprising the calibration target image with a scanning device of the MFP device to create a first scanned image;
• identify a leading edge and a number of side edges of the print medium via a background pattern to determine a number of scan measurements;
• identify at least one position of the at least one fiducial within the calibration target image;
• calculate a calibration target error based on the at least one fiducial and the scan measurements.
