Because touch pad is miscalibrated, can not naviagte to diagnostics and enter dC305 UI test.
Is there a way to use key pad sequence such that I can calibrate touch screen?
A service tech would be need to do the calibration through a special Diagnostics mode.
I found on 3635 supprot section that one should be able to press *,C,# to get to diagnostics and then C, to start calibration. I will not be able to try this until I get machine back from repair company that wanted $400 to do this!
