PROBLEM TO BE SOLVED: To easily determine/input the altitude in an electrophotographic printing system without any operator's intervention. SOLUTION: A method for determining an altitude with a corona generating device having a grid and a coronode and a power supply for supplying power to the grid and coronode, including: setting the grid at a predefined voltage with the power supply; applying a charge output voltage and a charged output current to the coronode with the power supply; monitoring the charged output voltage and the charge output current to the coronode from the power supply until a predefined charge output voltage is reached; correlating charged output current to an altitude when the predefined charge output voltage is reached.
