Abstract
A scanning method that saves time by reducing calculations performed in a scanner. The scanner has a housing, a transparent platform installed on the housing, a document positioned on the transparent platform, a scanning module, a calibration paper, a memory, and a processor. If an effective image range has been determined within a predetermined amount of time after the scanner is turned on, the effective image range will not be redefined before scanning the document.
