A scan image correction device includes a scanning part to scan an image of a document in a block unit, an electro static discharge (ESD) determination part to determine a presence of an external ESD while the scanning part scans the image, a document feeding adjustment part to feed the document backward by the block unit to allow the scanning part to re-scan the image if the ESD determination part determines that the ESD present, and an image process part to receive the image as an ESD free scan image and to process the received image. Accordingly, the scan image correction device prevents one or more black lines from appearing by an influence of the ESD during scanning so that a high-quality scan image can be provided.
