Abstract: A system and method are provided for determining a light output of a light emitting diode (LED) in a scanner. The system includes a processor circuit to execute current control logic to obtain an optimum light output from the LED. The current control logic repeatedly applies increasing or decreasing currents to the LED until a saturation point is identified. This may be accomplished, for example, by comparing two measures of the light output of the LED for two different currents applied to the LED. When a difference equaling a predetermined threshold between the two measures is detected, then the saturation point is identified.

Abstract: A method and system of selectively and securely enabling an added or premium functionality in a printer can be created by transmitting or inputting to the printer an electronic key correlated to the unique serial number stored in that printer. In this way, the key used to activate an added or premium functionality in a particular printer cannot be used to activate the same functionality in any other printer. This prevents the unauthorized activation of added or premium functions in other printers.

Abstract: A system and method are provided for calibrating an output from a sensor array in a scanner. The system comprises a processor circuit having a processor and a memory. Stored on the memory and executable by the processor is the scanner calibration logic. The scanner calibration logic comprises logic for determining a minimum dark value for the sensor array, and logic for determining an optimum exposure time of a number of light sources associated with the sensor array. The scanner calibration logic also includes logic for determining a maximum white value for the sensor array at the exposure time, and logic for setting an analog offset based upon the minimum dark value. The scanner calibration logic further comprises logic for setting an analog gain associated with the sensor array based on a sensor output range from the minimum dark value to a maximum white value.
