- FIG. 2 shows a block diagram of a printing system with connected maintenance computers
- FIG. 3 shows a block diagram for processing and displaying trace data according to the prior art
- Fig. 4 shows a block diagram for processing and displaying trace data of a trace data stream according to the invention
- 5 shows a flowchart for processing the trace data stream
- FIG. 6 shows a screen printout for displaying analysis data of the trace data stream.
- FIG. 1 shows a technical process 10 of a printer which comprises three components 12, 14, 16.
- Each of the components 12, 14, 16 contains both hardware elements, firmware and program elements for providing control functions and for processing data, especially useful data.
- the trace data generated by the respective component have a different data structure.
- the trace data preferably contain information about operating states and control and user data of the respective component to be processed. Due to the different data structure, the trace data cannot simply be analyzed and evaluated together. This problem occurs particularly in high-performance printers in which several components from different manufacturers are contained in one printer.
- a common evaluation of the trace data of several components is then not possible in the prior art.
- the trace data is thus evaluated separately for each component.
- a separate program module is started and processed in the prior art that reads the trace data of a trace data type, analyzes it and displays it in a suitable manner.
- a comprehensive analysis of trace data of several components is only possible visually by a development engineer. Normal service technicians are often overwhelmed with such a visual analysis, particularly due to the large number of high-performance printers that need to be maintained. The cross-connection of trace data from several components is therefore only recognizable to specialists.
- there is no uniform time base for the trace data which enables an exact statement about the sequence of trace data of several components. Reading out the trace data from individual components of the printer also often requires different operator actions, which makes it often too complicated for operators to download the trace data of a special component and save it on a data carrier for the printer manufacturer to analyze to send.
- FIG. 2 shows a printing system 20 in which a host computer 22 transmits print data to the printer 24.
- the printer 24 contains both a first control unit, the so-called controller, and a second control unit, the so-called device electronics.

- trace data with a different data structure ie from different components or control units of the printer are to be analyzed and processed with the aid of the system 30, in the prior art the personal computer 26 must first be connected to an interface of the first control unit of the printer 24 , whereby first trace data are read out.
- the first read-out trace data are processed and analyzed with the processing program module 34 and the processed data are output on a display unit of the personal computer 26 using the display software 36, as already described.
- the personal computer 26 is connected to an interface of the second control unit of the printer 24, second trace data having been read out from this control unit.
- a second processing program module which is different from the first processing program module 34 and with which the second trace data has been processed and analyzed, has then been loaded.
- FIG. 4 shows a system 40 for processing and analyzing a trace data stream 42 according to the invention.
- the trace data of the individual control units are combined in the printer or copier to form a trace data stream, which is saved in a file.
- This file with the trace data of several control units is then transmitted to the maintenance computer 26 for analysis and display.
- the processing software 46, the analysis instructions 44a to 44d and the display program modules 48a to 48c are contained in the maintenance computer.
- the processing software 46 selects the analysis rule 44a which searches the trace data stream for preset data sequences, so-called keys.
- the length of the data assigned to this key ie the memory area in which this data is stored, is contained at a fixed preset distance from the key. This length is read out by the processing program 46, one of the further analysis instructions 44b, 44c, 44d being selected depending on the specific key determined, in order to further process the data associated with the respective key.
- a first key is assigned to the trace data generated by the first control unit and a second key is assigned to the second trace data generated by the second control unit. If the processing software 46 determines the first key in the trace data stream, the associated data defined by the specified length are processed further with the aid of the analysis rule 44b assigned to the first key. The trace data identified with the aid of the second key and generated by the second control unit; second key-assigned length are further processed with the aid of analysis rule 44c, which is assigned to the second key. The second trace data are then searched for a further third key with the aid of the processing software, the data identified by this third key then being further processed and analyzed with the analysis rule 44d when the key is found.
- the trace data preferably contain a so-called structure area, which contains the key and the length field, and a so-called data area, the data of which are further processed by processing software 46 depending on the key.

- the data is output on a graphical user interface in which the data format by the user, e.g. can be easily selected by the service technician.
- the individual analysis instructions 44a to 44d are preferably stored in separate files in a memory area, preferably on a hard disk, of the personal computer 26. As a result, further analysis instructions 44a to 44d can be very easily incorporated into the processing analysis and display system 40 can be integrated. It is then very easy to adapt the system 40 when additional control units of the printer or copier are added or when changing the data structure of the trace data, individual control units of the printer. The data structure of individual trace data is therefore contained in the analysis instructions 44a to 44d. If more than two control units are provided in the printer or copier that generate trace data, then alternatively a trace data stream with trace data from selected control units can also be generated. Furthermore, the operating events and user data to be recorded in the trace data of the individual control units can be individually preset for each control unit. This makes it very easy to generate a problem-oriented trace data stream.
- the trace data contained therein of the individual control units are assigned unique trace type designations, in particular with the aid of keys.
- the trace data is divided into structure areas and data areas in the trace data stream, the structure area in particular containing information about the key and information about the length of the data area.
- the trace data generated by the individual control units of the printer dynamically, ie continuously, so that there is always a current trace data stream in the printer and the trace data for error analysis is not first combined in a trace data stream Need to become.
- By dynamically combining the trace data of several control units at least the order of the operating states contained in the trace data can be easily determined.
- Additive- The trace data generated by the control units can contain a time stamp generated by the control units and, additionally or alternatively, can contain a time stamp when the trace data is added to the trace data stream.
- Trace data that are older than one day can be automatically deleted from the trace data stream in one embodiment of the invention.
- the time period after which the trace data are to be deleted can be preset as parameters in the printer or copier.
- the trace data of several control units can also be simply summarized in a problem-oriented manner.
- individual events contained in the trace data can be linked to one another in terms of time, for example by outputting the operating events contained in the trace data in a list in the chronological order in which they occurred. This enables a very clear chronological sequence of operating events of several control units of the printer.
- the trace data are preferably divided into at least one data area and one structure area.
- the structure area contains in particular the data type of the data contained in the data area and the type of data display.
- the length of a data field such as bytes or word long
- the data format such as ASCII, EBCDI or HEX
- the type of data such as image, sound, video or statistical data
- the structure area contains at least one length field by which at least the size of the data area is determined.
- both the structure area and the data area contain a so-called header, which contains further information about the data stored in the data area and / or in the structure area.
- the type of display of the data contained in the data area is preferably determined for this data object by the preset display rule 48a to 48c in the processing software 46 and / or in the analysis rule 44a to 44d.
- the processing software 46 uses several trace data types for display, the method according to the invention which has already been explained.
- the analysis instructions 44a to 44d are stored in so-called Structure Define Language files (SDL files), which, as already explained, are used by the processing software 46 to process the trace data stream 42.

- the processing software 46 By loading the analysis instruction 44a into the main memory, the processing software 46 has access to the analysis instruction 44a stored in the file.
- the processing software 46 then uses the analysis rule 44a to process the supplied trace data stream and in doing so interprets and analyzes the data contained in the diagnostic data stream in step S110.
- the trace data is broken down into trace objects using a parser.
- a trace object contains an offset which specifies the distance from the beginning of the file, a length of the object, ie the number of bytes of the trace object, the preferred display format and a description text for each display element.
- the display is selected, whereby conversion tables are selected by which the trace data are processed or converted.
- trace data in HEX, EBCDII and ASCII data format are converted into the ASCII data format according to the respective conversion table.
- sequence of the trace data can be changed.
- the bytes of the file formats WORD and LONG can be rotated, ie the LOW bytes and the HIGH bytes are interchanged, which means that the data sequence 0010 in Intel data format is converted to data sequence 1000.
- a display program 48a is selected on the basis of the analyzed data in accordance with the display format specification in the trace data for displaying the data processed in step S 110.
- the display program 48a is selected using the parser used when processing the trace data. Furthermore, the processed data to be displayed are transmitted to the display program 48a in step S 112.
