Abstract: The present invention relates to the image correction device of the combination apparatus for eliminating the step difference of the image data by compensating the image step difference quantity occurring according to the environment or the transport or the assembly allowance of the carriage mechanism automatically when the data are read with the shuttle scanner module used as the reading means of the data, the image is corrected automatically within the system itself by correcting the wrong data with the image correction table and recording on the buffer by first reading the beginning data at the beginning driving of the system so the production time is reduced and the cost of the apparatus is lowered as the result of the reduction of the prim cost and the precise image is secured because the image is corrected automatically also under shocks in movement or the environment when a user buys and transports and uses it after it has been produced, therefore the reliability of the product improves.

Abstract: An apparatus and a method for correcting image errors in a shuttle type of a scanner, in which a predetermined pattern is printed on a recordable paper. Then the recordable paper is positioned at an initial position, and the printed pattern on the recordable paper is scanned and scanned pattern data are stored. The pattern data are then compared to preset reference data so as to calculate an amount of image errors. Continuously, the amount of corrections corresponding to the amount of the image errors are determined from a preset correcting table and the amount of the corrections are stored. Finally, a document is scanned and scanned document data are corrected by the stored amount of corrections. Accordingly, the stable data can be obtained by correcting the image errors in the shuttle type of the scanner in such a manner as described above.
