But the scanner is no more recognized. Scanners that are affected are(besides others): - Epson Perfection V10 - Epson Perfection V1000 - Epson WorkForce GT-1500 - Brother MFC-8510DN - Epson Perfection V33 It is to note that the probability that the scanner manufacturers fix things others broke is below 100%.
