    MXB427W touch screen

    Anyone know how to calibrate the touch screen on this Sharpmark? The screen starts rolling up or down when your finger gets touches the screen.

    Unfortunately, there is nothing in the service manual about calibrating the screen. This is low budget Lexmark. You probably need to replace the screen with a new one (Control Panel Assy 41X2595). Once I had a case when after a while the screen stopped responding to touch and I had to replace it.
