I have been using 2 different programs for scanning, Orpalis & NAPS2 with my Samsung MFP. This past week, both programs have indicated error messages when trying to scan with TWAIN. If I switch to WIA, NAPS2 works, Orpalis not. I have reinstalled both programs from clean. I am running latest Windows 10 64 bit. The printer has all the latest Drivers.
