DOCUMENT PROCESSING APPARATUS WITH IMAGE SCANNING RESOLUTION CORRECTION FUNCTION AND METHOD FOR CORRECTING IMAGE SCANNING RESOLUTION

PROBLEM TO BE SOLVED: To provide a document processing apparatus with an image scanning resolution correction function, and a method of correcting an image scanning resolution of the document processing apparatus. SOLUTION: An embodiment of a document processing apparatus includes: a first reflector that reflects reflected light from a document fixed on an original placing glass plate in a predetermined direction; a second reflector that changes a direction of incident light from the first reflector by 180 DEG; first and second driving units for moving the reflectors in the same direction; first and second driving control units for controlling the driving units; and first and second memories for storing control parameters including parameters of a default setting state specifying control operation of the driving control units. The second memory further stores a parameter relating to correction from the default position of the second reflector. The parameter relating to the correction is obtained in advance so as to obtain a predetermined resolution in plural scanning positions of the first carriage. COPYRIGHT: (C)2008,JPO&INPIT
