Definitions

  • Printing or copying devices are generally made up of several units, each unit being able to consist of modules. Examples are the printing unit and input unit or output unit for a printing material. Such a printing device is e.g. removable from WO 98/18052 AI. There the printing unit has two printing units, which as modules e.g. contains a photoconductor drum, components for generating charge images on the photoconductor drum, a transfer printing module, a fixing module, modules for determining the transport path for the printing material through the printing unit, etc. In addition, an input unit at the input of the printing unit and an output unit for the printing material, e.g. a stacker is provided at the output of the printing unit.
  • modules e.g. contains a photoconductor drum, components for generating charge images on the photoconductor drum, a transfer printing module, a fixing module, modules for determining the transport path for the printing material through the printing unit, etc.
  • an input unit at the input of the printing unit and an output unit for the printing material
  • EP 0 810 484 A1 describes a transport system for a printing material, in which the individual units of the transport system can carry out their task automatically after they have received control information from a central controller.
  • the units are designed in such a way that they can carry out self-diagnosis and self-repair, whereby these activities can be carried out in parallel with the central control system. If the central controller has identified an error, it gives control information to the units in which the type of error is specified. With this information, the unit tries to remedy the error autonomously.
  • EP 0 416 919 A2 discloses the synchronization between image scanning and paper transport in a copier. Copying will stop if it is determined that the paper feed is too slow.
  • EP 0 583 928 A2 describes a device with which the paper feed in the transport path for the paper can be checked. To do this, the speed of the transport rollers for the paper is measured. If the measured speed does not correspond to a predetermined speed, an error signal is generated.
  • the control units provided for operating the units under the supervision of a main control unit are additionally used to check the modules of the unit for errors and, if a remediable error is found, to remedy this error.
  • each module can advantageously be checked in succession per unit, it being expedient to eliminate a printing material error by starting with the last module as seen in the transport direction of the printing material and examining the adjacent and previous modules one after the other. At the end of the test process, the error (s) are eliminated or a status signal "Error not corrected" is issued.
  • Another advantage is that a module that works incorrectly is examined to determine whether operation is possible without this module and, if this is possible, to report this. Further developments of the invention result from the dependent claims.
  • the troubleshooting can be carried out separately for each unit in this way. However, it is also possible to test all units one after the other in the opposite direction of the transport path of the printing material, and possibly. correct any errors found, if possible.
  • Fig. 2 is a flowchart of the method.
  • switch modules W through which the sheets of the printing material can be fed to output containers 32 to 36 or output channels to the following units, such as stackers, or in the input unit 16 there are storage containers 18 to 24 for the sheets of printing material and an input channel 26, to which printing material can be fed from other input units, is shown.
  • control units ST The individual units of the printing device DR are controlled by control units ST, the printing unit 10 by the printing control unit D-ST, the input unit 16 by the input control unit E-ST and the output unit 30 by the output control unit A-ST.
  • control units ST are connected to a main control unit H-ST, which coordinates the operation of the printing device DR.
  • the control units ST are of known construction and are therefore not explained further. Examples of this result from WO 98/39691 AI.
  • an error now occurs in the printing device DR during transport of the printing material for example a jam of the printing material, it must be determined in which unit and in which module of the affected unit the error has occurred. It must also be determined whether the error can be remedied without operator intervention.
  • the control units ST are used, which have so far given "error messages" to the main control unit H-ST when such errors occur, from which it can be seen where the error occurred.
  • the aim of the invention is now to use these error messages in order to automatically eliminate the error, if possible.
  • the prerequisite is that there is a fault in a module that can be remedied without operator intervention. If, for example, there is a fault in a switch module W, you can try to clear the transport path for the printing material by changing the switch position.
  • step S3 If the fault can be remedied automatically (step S2), the corresponding control unit D-ST changes to the unit fault remediation mode (step S3).
  • step S4 a command is issued by the control unit D-ST to the module, which is located at the exit in relation to the transport path of the printing material, which causes this module, for example the switch module W4, to empty the transport path for the printing material.
  • step S5 the module tries to empty the transport route. Whether this was possible is checked in step S6. If the error can be rectified, the assigned control unit D-ST reports the status signal SSI "error rectified" in step S7. Subsequently, in step S8, a query is made as to whether all modules of the unit have been processed.
  • the method can also be used in such a way that the entire printing device DR is examined, first the modules of the output unit 30 for the printing material, then the modules of the printing unit 10 and finally the modules of the input unit 16.
  • Errors that occur in the transport path of a printing material in an electrographic printing or copying device are automatically eliminated as far as possible with the described method.
  • the individual modules of the units of the printing device are successively tested opposite to the transport direction of the printing material with the result of whether the module can eliminate the error or not, and in the second case it is also examined whether this module can be bypassed.
  • the status of the module checked and, depending on the result, the printing process resumed or the printing device stopped.

Abstract

L'invention concerne un procédé servant à éliminer autant que possible automatiquement des erreurs survenant dans le chemin de transport d'une matière à imprimer dans un dispositif d'impression ou de reproduction électrographique. A cet effet, les différents modules des unités du dispositif d'impression sont contrôlés successivement, à l'inverse du sens de transport de la matière à imprimer, afin de savoir si le module peut éliminer l'erreur ou non et, dans ce deuxième cas, si le module peut être évité. A la fin de la procédure de contrôle, l'état de chaque module contrôlé est interrogé et, selon le résultat, l'impression reprend ou le dispositif d'impression est arrêté. Si un module fonctionne mal, le procédé vérifie si le fonctionnement est possible même sans ce module ; dans l'affirmative, un message signale que c'est possible.
