A slot scanner, for generating a scanned electronic image of a document, comprises a housing with a slot configured for manually feeding the document through the slot, so that feed mechanisms are not necessary. The slot extends completely through the housing and has first and second openings. The slot defines an interior surface of the housing. The following components are positioned on the interior surface: an image sensor extending over substantially the entire length of the slot, a navigational sensor, and an illuminator positioned proximate to the image and navigational sensors. The scanner includes an image processor enabled to track movement of the document and to generate an electronic image of the document based on data from the image and navigational sensors. A method is described for removing image distortion artifacts from the image data, arising from the non-uniform way in which the document may be moved through the slot. This method utilizes data from the navigational sensors.
