Some people had problems with them. I'd say if you simply check the forms for errors and dust them off before putting them in the bins, you'll get a piece-by-piece copy with the front page and thumbnails intact. So make your master as perfect as you can. Just a small catch. My first entry showed the word Fail - 0 on the display. means it's gone. If it failed, there is a number indicating the failed tray. If it passes successfully, you might think the display will say 'pass'. Otherwise, just place your master in the top tray, blanks in the bottom trays, and press enter. He does everything else. Note that it has many self-test functions, so don't lose the user manual! It explains everything.
