The touchscreen on my printer is unresponsive. The only buttons that work at the back and question. It's currently giving me a message on ink that needs to be replaced. I've got new ink properly installed and it won't let me cancel that message or go to the home screen. It's currently a useless printer that will turn on/off but won't print/scan/copy. I've done the power restart and taken the ink cartridges in/out. Help?!
