A simple, yet accurate way of determining calibration values for correcting the characteristic sinusoidal feed errors of a printer or other recording device (such as a fax machine, plotter, etc.). A sheet of calibration media is employed for facilitating the calculation of the calibration values. The sheet is used in a way that prevents the calibration media errors from affecting the calculation. In particular, the sheet of calibration media is fed twice through the printer, and position data is collected each time. The data is processed in a way that cancels the attendant calibration media errors so that the calculated calibration values precisely correct the characteristic sinusoidal feed errors of that printer.
