Hello I downloaded your program last week to use with my Lexmark MC2425.
It worked well for a couple of days.
I tried to use it today and got the following error message
NAPS2.Scan.Exceptions.ScanDriverUnknownException: An error occurred with the scanning driver. ---> NAPS2.Scan.Wia.Native.WiaException: WIA error code 80070057

Sorry I forgot to mention that I turned both the computer and printer off and on several times without effect
