Hi Patrick, It seems that we have a general problem with ADF scanning from all Maxify scanners.
If possible, please provide USB logfiles from a Windows machine scanning from ADF and duplex ADF, one page and two pages, using Wireshark. Then I can try to fix this. In the meantime I'll update the doc files. Many thanks for your help. Cheers, Rolf Am 28.01.2018 um 15:26 schrieb Patrick Roncagliolo: > Hi Rolf, > > I tested scanimage with different options today.
