METHOD AND CONTROL DEVICE FOR DISPLAYING DIAGNOSIS DATA OF A PRINTER OR COPIER

In a method for outputting data of a diagnosis data stream of a printer or copier, the diagnosis data stream comprises first data of a first data type and at least second data of the second data type, the first data and the second data each including structure date and use data corresponding to the respective data type. The diagnosis data stream is supplied to an evaluation program of an evaluation unit for evaluating the first and the second data. The structured data of the first data is analyzed with aid of the evaluation program, a first identification which is characteristic of the first data type being determined. Upon the determination of the first identification, selecting a first evaluation instruction from a plurality of evaluation instructions with aid of the evaluation program and loading it, the use data of the first data being evaluated with aid of the first evaluation instruction. With aid of the evaluation program it is verified whether the evaluated first data include further data areas comprising the second data which can be evaluated with aid of a further second evaluation instruction which can be selected from the plurality of evaluation instructions. The second data is analyzed with aid of the evaluation program, a second identification which is characteristic of the second data type being determined. Upon the determination of the second identification, the second evaluation instruction is selected from said plurality of evaluation instructions with aid of the evaluation program and loading it. The second data is evaluated and output with aid of the second evaluation instruction.
