I got a problem with a Lexmark X5500 MFP Option.
From one day to the other the touchscreen was "decalibrated", means you have to tip one button to th eleft to get the richt one (about half an inch).
I thought that'll be no problem, just calibrate again.
So I got into the menu (over the key button) to touchscreen calibration, to push the twelve points. But I'm not able to push the three left ones, evereytime I try I get three beeps (3 short beeps), means error.
So I tried to reset the MFP to feactory defaults, by service menu **411, but it hasn't made any change to the touchscreen problem.
Any idea would be highly appreciated!
Thanks in advance!
Christian
