| Question: | The scanner automatically re-sets up itself when Prescan or Scan button is clicked. Why? | Answer: | The re-set-up is to collect the information of uneven light on the CCD, which varies depending on the lighting duratino and focus position. When a certain period of time passes after the fluorescent is turned on, or when the focus position is shifted, the scanner re-sets up itself to achieve more accurate shading compensation. |
