Does anyone know more about the white calibration strips on modern flatbed scanners? I'm looking to replace mine, not sure if there's a particular set of parameters I should stay within. I.E. 75%, 80%, or 99% Reflectance values Epson 10000XL & 11000XL scanner model Epson does not provide this strip as a part I can order. It's only available as a complete upper assembly replacement. Not what I want or need. Any suggestions, advice or knowledge on these calibration strips is appreciated!!!1 Andre
