Now you should see the touch panel menu. I believe it is #1, the top left button to calibrate. You basically touch 2 circles and hit enter or #. Probably a good idea to use a pen or something with a fine point. GL
On this model the touch screen is more than likely about to fail if the calibration is drifting.
TonerMunkeh is correct. If is is messing up order another one. Many and we mean MANY of the new models Touch screens are crap. There are bulletins and plenty of questions and rants about it on CopyTechnet.
