Abstract

A device and a method are provided for recharging a belt conveyor which is used for transporting a printing medium in the transfer area of an electrophotographic printer or a copying machine. The device includes a blade-like contacting element which is adjacent to the belt conveyor and arranged transversally with respect to the forward motion thereof. The contacting element makes it possible to transfer an electric charge to the belt conveyor and is mounted on a bearing element which can be inserted into a printer or a copying machine and withdrawn therefrom. A method is provided for controlling a printer or copier device by which errors, such as paper jams, can be cleared automatically. A controller commands a module having the error to clear the error automatically. The commands are sent to modules beginning at the output of the printer or copier device and moving in a reverse direction to the paper flow direction of the printer or copier so as to automatically clear errors such as paper jams. Status signals indicating whether the error has successfully been cleared are reported back to the controller. A printer or copier for carrying out the method and a computer program for car…
