Abstract:
An image processing apparatus, comprising:a carriage configured to carry an image reading device; a white plate configured to be read by the image reading device for adjusting a reading level of the image reading device, said white plate being arranged above a track of said carriage; a home position sensor configured to detect a position of said carriage; a controller configured to control a movement of said carriage, said controller moving said carriage based on an output of said home position sensor to perform an initializing process of the image reading device including a homing operation and a white plate reading operation, wherein said controller is configured to (1) determine a direction of the movement of said carriage based on the output of said home position sensor when the initializing process is initiated, (2) perform a tentative homing operation of the image reading device when said home position sensor changes the output after said carriage is moved, and (3) move said carriage to a white plate reading position based on the performance of the tentative homing operation.
