Hello har digi. I wish I had better news for you, but if your scanner only shows a dot and not a line, it means that something has gone wrong with the scan engine. This is fixable, however you'll probably end up spending as much getting it repaired as you would buying a whole new scanner. If you'd like to send me a message or email, I'd be happy to recommend some scanners that would work just like the one you're using and have a low price-point. I hope this helps. Good luck!
