The 4 arrow keys around the circular "select" key are super touch sensitive, it jumps 2 or more settings when you try an entry, no matter how hard or soft you touch them. If you press the button and hold it down, it scrolls through the settings over and over. I installed a brand new operation panel and updated firmware, but it is still the same. The buttons only make one click when you touch them, so it does not seem to be "double entry". I know some copiers have a "touch sensitivity" adjustment or "panel calibration", but they are mostly touch panel machines.
