Abstract: In a method for initializing an image scanner having a scanning module and an automatic document feed (ADF) glass, the scanning module is moved in a forward direction toward the ADF glass to search for a reference mark located within a relatively close proximity to the ADF glass. The scanning module is moved forward to search for a black-white transition in response to the reference mark being located and the scanning module is moved in a backward direction away from the ADF glass in response to the black-white transition being located. The scanning module is stopped when the image sensor of the scanning module is aligned with an origin mark to thereby accurately position the scanning module.

Abstract: A method and mechanism to set a platen glass of an image reader by demounting the platen glass after the platen glass has previously been position-adjusted and positioning means have been fixed to this adjusted position and then achieving the desired positioning by these positioning means before the platen glass is mounted again on the image reader. Upon completion of optical adjustment, the platen glass is temporarily fixed to a casing of the image reader and then the platen glass is position-adjusted until image data formed on a test chart sheet coincide with predetermined image data. After the adjustment, positioning blocks are secured to top-plates of the casing and a glass retaining plate is secured to these top-plates. Subsequently, the platen glass may be mounted on the image reader in operative association with these positioning blocks to set the platen glass to the adjusted position.
