The invention provides a homing method for a scanning device and a scanning module thereof. A positioning plate of the scanning device is arranged on the inner wall of a shell; the scanning module indentifies at least one X axis side image corresponding to the positioning plate and determines a starting line for scanning according to the X axis side image. The homing method identifies at least one X axis side image corresponding to the positioning plate by capturing images between the positioning plate and the inner wall of the shell of the scanning device and determines the starting line of scanning according to the X axis side image and captures the image of a document to be scanned by moving along a Y axis direction from the starting line for scanning. The scanning module of the invention can accurately carry out homing and positioning, thus completely capturing the image of the document to be scanned and correspondingly improving the quality of the scanning. Meanwhile, a monochromic positioning plate can
