Method  for estimating the accuracy of astrometric  (rectangular coordinates) and photometric (diameters and magnitudes) characteristics of commercial scanners is proposed and applied. The method is demonstrated using an example of processing of sequential scans of plates, which were exposed with different  telescopes and then digitized with  resolution  of  1200  dpi with several  Epson scanners. Scanning operations were carried out in various observatories as part of development of  the database of photographic observations  for  Virtual Observatories  (Vavilova, 2012). Errors of studied scanners are equal to σx, y = ± 0.02-0.06px and σm = ± 0.015-0.024 mag for astrometry and photometry, respectively.
