ABSTRACT:
The present invention provides a sheet-fed scanner which can preview a document. The sheet-fed scanner comprises a housing having an opening for feeding a document to be scanned, a scanning module installed in the housing for scanning the document, a driving mechanism for driving the document forward and backward, first and second sensors installed at a front end and a rear end of the driving mechanism for detecting the document, and a control circuit for controlling operations of the scanner. When the document is fed into the opening and detected by the first sensor, the control circuit uses the driving mechanism to drive the document forward until the document is detected by the second sensor. And when the control circuit receives a preview instruction, the control circuit uses the driving mechanism to drive the document forward and uses the scanning module to perform a preview scan over the document until the document is no longer detected by the first sensor. And then the control circuit will use the driving mechanism to drive the document backward for a normal scan.
