ABSTRACT:
A method and a device for adjusting the printing position of a printer head. When a recordable medium having a greater thickness than that of a standard cut sheet of letter size paper is inserted in an electrophotographic apparatus, it is often necessary to increase the distance between the top recordable medium in the paper supply tray and the paper input port in the electrophotographic apparatus to allow a greater number of thick sheets of recordable medium to be loaded. One method of increasing the distance is to rotate a guide panel into a position that abuts the electrophotographic apparatus and increases the distance between the paper supply tray and the paper receiving port. Unfortunately, this causes the printer head to require adjustment, as the horizontal positioning of the printable medium fed into the printer has changed. This inventive method and device uses a sensor to determine when the guide panel has been rotated and automatically adjusts the printer head's position.
