This paper assesses the viability of using a flatbed scanner to measure motion quality of a printer. The procedure utilizes previously printed reference marks from a high quality printer next to which a ladder chart of a given frequency is printed on the machine to be measured. The resultant print sample is scanned and processed to obtain centroid locations. A correction is applied to the printer positional error prior to Fourier analysis. This paper will investigate the accuracy of this method in determining positional errors incurred and removing scanner contribution.
