That is my assumption as well. But please note that the 0x59 value comes from Alessandro Zummo and was already existing in the epson2 driver. I did not verify it yet because I was only scannning on glass. We might need a custom value later in case we build some frame, too, to avoid glass on glass contact. We will see. > Welcome and hope this helps, Yes, it did. Thank you!
