Abstract: In a method and arrangement for authenticating a data processing system, first information is generated by a first data processing system and delivered to a second data processing system for a control unit. First data are transmitted from the second data processing system to the first data processing system over a data line, the first data being generated by the second data processing system with aid of the first information and additional information contained in the second data processing system. Second data are generated by the first data processing system depending on the first data and transmitted from the first data processing system to the second data processing system. Authentication information for authenticating the second data processing system is generated by the second data processing system with aid of the second data.

Abstract: In a method or system for loading of program data for a graphical user interface for operation or for diagnosis of a printer or copier, first data are stored in a first storage region of a first data processing unit. The first data are transferred from the first data processing unit to a second data processing unit of an operating unit, the first data containing at least specifications about at least one program module necessary for generation of operation or diagnosis functions. With help of the second data processing unit, it is checked whether second data that contain the program module are contained in the second storage region of the second data processing unit. A version state of the program module stored as second data in the second storage region is compared with a version state of the necessary program module.

Abstract: In a system and method for maintenance of a printing or copying system, at least two system computers are provided comprising a central device control computer and a raster process computer. A print data network connection is provided for incoming print data or copy data to be rastered. A print data network connection is provided for incoming print data or copy data to be rastered. At least one of the system computers is designed as a service connection computer. A maintenance computer is connected to a maintenance data connection on the service connection computer. Control programs are loaded from the maintenance computer onto the service connection computer via a network connection.

Abstract: In a system and method for remote maintenance, remote configuration and/or remote operation of an electrophotographic printing or copying system, a data processing system is connected with a communication unit of the printing or copying system via a network. Given a deactivated printing or copying system, the communication unit receives first data transmitted by the data processing system via the network and processes the transmitted first data. After receiving the first data, the communication unit activates a data processing unit of the printing or copying system. After the activation of the data processing unit, second data can be transmitted between the data processing system and the data processing unit.

Abstract: In a method and a system to configure an electrophotographic printing or copying system, a first data set and at least a second data set are stored in a databank. The first data set comprises at least a value of a first default value and the second data set comprises at least the value of a second default value. A first program element reads out the value of the first default value and the value of the second default value from the databank with the aid of databank interrogation commands. Data with the value of the first default value and with the value of the second default value are transmitted to a first data processing system of an operating unit of the printing or copying system, whereby the data are supplied to a second program element executed by the first data processing system. With aid of a second program element, the data are transmitted via a data connection from the first data processing system to a second data processing system of the printing or copying system.
