You can't scan anything with a printer, you need a scanner.





Some devices contain a printer and a scanner in one unit, if you have one of those then you haven't provided enough information for anyone to help you:





- where is this scan button you are clicking?


- what model of scanner is it?


and, most important:


- what does the error message say?!
