While setting up a network at an office, the owner asked if I knew anything about copiers, I should have said no! The LCD touch screen calibration was way off, you basically had to touch below and to the right of the button you want to activate. A bit of Google searching and I found how to access the calibration menu item. From this copytechnet.com article, user D_L_P, mentions you have to press the yellow Reset button, followed by the numbers 1,9,9,3 in sequence and then the red stop key 5 times. One annoying thing is while pressing the 1993 sequence (and it might be just this Savin model: 8025), pressing 1, the machine beeps, pressing 9, the machine beeps, pressing the next 9 the machine beeps, then the final 3, the machine DOES NOT beep. This makes you think you did not press the button or it did not register and you end up pressing it again. It did however register and for some reason does not beep. Once you finish that sequence, and pressing the stop button 5 times, you are presented with a set of menu items, to calibrate is item #1. It will then ask you to use a sharp object and press a tiny little circle on the screen, I just used the end of a key, then it requests you press a second circle with the sharp object. Once that is done you are finished and the LCD should be calibrated.
