Abstract:
A scanning device includes a housing, a cold cathode fluorescent lamp (CCFL), and a light emitting diode (LED), a photosensor for detecting light that is emitted from the CCFL and the LED and then by way of a document, and a control circuit for controlling operations of the scanning device. The LED can be used to perform scans while the CCFL is heating.
