This is when I enlisted the aid of my coworker who had the only working one of the bunch. Bad power supply. Here is where the story gets really ugly. I called the CGDW and informed them that the scanner was not working and could they replace it. No, I said you guys can pay.
Second scanner comes, crappy imaging with lines all up and down the picture.
Same song and dance. Third scanner comes, power supply case is cracked in half and no calibration card. I call again. This scanner is useless without the calibration card. Luckily they find one for me.
