Device and method for adjusting printing position of a printer

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.

FORCELESS SUPPORT FRAME FOR PRINTHEAD SHUTTLE IN DIGITAL PRINTERS

In a digital printer the elements involved directly in the print process, which are located on a shuttle assembly are mounted upon a metrological frame which is isolated from the base frame by vibration dampers. Because the elements of the shuttle drive systems, such as a belt drive system having a motor and pulleys, are mounted upon the base frame, the drive and reaction forces from the motor drive systems are led to the base frame while the shuttles assembly is guided by the force-free, vibration free metrological frame. This allows for higher accuracy during printing as the metrological frame serves as a vibration free reference element.
