Patent ID: 7536118

Claim:
A method for automatically correcting an error during operation of an electrographic printing or copying device, comprising the steps of: determining whether the error can be automatically corrected in a main error correction mode, and in case the error cannot be corrected, ending the main error-correcting mode; in case the error can be corrected, switching individual modules to an error-correcting mode in succession; querying the individual modules in a sequence opposite to that of a printable media transport direction, said querying including testing a first module by transmitting a command to correct the error to said first module, said command including instructing the first module to move the printable media in the media transport direction in order to clear the first module, transmitting a status signal indicating that the error is corrected if the error correction is successful or if no error is present, otherwise transmitting a status signal indicating the error is not corrected, if the status signal indicating that the error has not been corrected in the first module is transmitted, making a determination as to whether operation of the electrographic printing or copying device can proceed without the first module that has the error and, if so, transmitting a status signal indicating that operation is possible, otherwise transmitting a status signal that the error is not corrected, and testing the further modules preceding the first module and clearing those modules if necessary; and if after checking and attempting to clear the modules, the status signal indicates that the error has not been corrected in at least one of the modules, then ending the error-correcting mode and reporting the module registering the error, otherwise ending the main error-correcting mode and transmitting a status signal indicating that the error has been corrected.
