How do I reset printer to factory defaults?

I turned off my printer after getting to the touchscreen calibration assuming it would just reboot without saving.  My touchscreen is no longer functioning.  I can't get to the touchscreen calibration because no touch is being registered.  How do I reset my printer or what can I do to get around this issue?

So I figured this out.  I took off the front panel.  On the main board, there's a reset button.  Pressed that, easy peasy, touch screen is working perfectly again!
