Hello everyone
This tool is created for people who own a scanner with a document feeder which isn't able to scan duplex (both sides of a sheet in one scan).
Note: This tool runs on all computer-platforms! :)
Step by Step:
1. Scan all sheets frontsided to one PDF-file.
2. Without changing the sort of the sheets, turn the whole bunch of sheets and scan it again (all the backsides). It's important to scan the same amount of pages (even the empty ones), like before! Otherwise it won't work...
