A scanner flipper oscillation frequency analyzing method, computer-readable medium, and apparatus is provided. In one embodiment, the method turns a laser off if the laser is on and receives a signal indicative of a flipper oscillation frequency. The method then compares the signal with stored parameters. Based on the comparison, the method adjusts the flipper oscillation frequency when a percentage variation between the signal and the parameters is above a predetermined value. If the flipper oscillation frequency is adjusted a Digital-to-Analog Conversion value associated with the adjustment is stored in memory. The signal received can be transition signals. In other embodiments, an apparatus and computer-readable medium is also provided which performs the similar features recited by the above method.
