Scanner Jam

Post by smgrisw » Fri Nov 13, 2009 1:44 am

I have a issue that I have not been able to resolve.

User starts scanning and scans several pages.
Scanner jams and the feeder tray is opened and the page is fixed
User continues to scan and when they are done with scanning they process the scans to PDF. The problem is that the scans that were done before the jam are missing the scans done before the jam are missing.

1. Does the process of the scanner jamming cause the number of images to be dropped?
2. Is there some other issue that might be causing the image count to reset back to 0?

Hello Scott,

Do not stop the device if paper is jammed, simple close the data source and start new acquisition process.

VintaSoftTwain.NET Library has built-in images buffer, this buffer cleared when:
  • StartDevice methods is called
  • StopDevice methods is called
  • Value of the MaxImages property is changed
Please read the documentation for more info.

Best regards, Alexander
