Have you tried looking up that exception message? It means "There are no documents in the document feeder."

I think you should be catching this exception and handling it appropriately.

Yes I did. I just don't understand why it is giving me that because it scans all the documents, and then it throws that. I just added in a try/catch to it, but it just throws the same exception. If I take the foreach loop out, the program works fine, but it only will scan one page and end.

You have done some sort of hard coding
scannerDevice.Items[1]

What is the output of the following statement
scannerDevice.Items.Count

Why use a for each loop if you don't use Property in the loop ?

C#

foreach (Property item in scannerDevice.Items[1].Properties)

You continuously scan all sheets of paper without checking if there is something to scan and you wonder why you get an exception when feeder is empty and nothing to scan ? Serious ?
Do you expect you code to stop scanning magically ?

Either you handle the exception or you test if there is something in the feeder.
