回复： showing error 15, 156 ,0.If you have a Mac this is what I did and it worked for me. 1 - Place image in scanner. 2 - Turn it on. 3 - Go to System Preferences 4 - Click on Printers and Scanners 5 - Click on the Scan button at the top center of the box 6 - Click on the open Scanner button. A grey Scanner box will appear. 7 - Push start on your Scanner and scanning will commence. I hope this helps.
