The present work has been performed to study in detail the Epson Expression 10000 XL scanner for photographic archive collection of the Ulugh Beg Astronomical Institute (UBAI) of the Uzbekistan Academy of Sciences. The specially developed software in the LINUX/MIDAS/ROMAFOT was used to process the plates. The test plate was digitized with grayscale 8 and 16 bits with different resolutions of the scanner. Astronomical and photometric parameters were obtained from the plate and an assessment of the accuracy of the developed method for determining rectangular coordinates and photometry, the repeatability of astrometric and photometric errors of the scanner for the digitized resolutions were processed.

Key words: Stellar catalogs, digitized plate processing, photometry, UBV system.
