If your model has not been checked for PaperScan yet the app throws a message before the first start. Nevertheless you can use the app and scan documents.

Lay the document on a high-contrast background withdocument and try to flatten it. Then the scan will triggered automatically in most cases. The recognition algorithms of PaperScan are looking for edges of your document. The algorithms rely very strongly on contrast, so a white sheet of paper on a dark table is ideal. Another key factor is the quality of your original. You should be able to recognize a set of four edges where two are relatively parallel to each other. If you can`t, the algorithms have a hard time recognizing the edges. PaperScan is optimized for iPhone 5. If you install it on an anterior model, you may have to capture scans manually and deskew the images by hand.

The focus of the scan depends on where your camera focused. There may be situations where the edge detection algorithms are quicker than the auto-focus of the camera. Just make sure your document is steady, and repeat your scan.

Due to complex algorithms, the app requires a lot of memory. For best results, close other apps and restart PaperScan.

The individual pages are combined into one PDF.

If the hard-copy original is still needed for tax etc.depends of the policies of your country and your business. To be sure, ask your accounting clerk or tax consultant.
