摘要:
A method and device controls a printer or copier to generate a plurality of marks that are assembled into a coherent marking band that is then inked by the toner. A sensor measures the marking band. The printer or copier are controlled based on the output of the sensor.
摘要:
A method for operating a printer or copier provides that error conditions are sensed utilizing monitoring units. A determination is made as to whether the error condition is readily repairable by the user and, if so, the display unit displays information on the error condition including instructions for repairing the error condition. If, on the other hand, the error condition is determined to be repairable only by a skilled technician, the display unit displays only the instructions to contact the skilled technician.
摘要:
In a method or system for controlling an electrophotographic printer or copier that has at least one developer station, a toner discharge from the developer station is detected during the print operation and a developer regeneration process is started when the detected toner discharge fulfills a predetermined first regeneration criterion. A charge image is generated on the photoconductor, the charge image is developed by the developer station, and the developed image is removed by a cleaning device without being transferred as printed onto a recording medium. New toner is introduced into the developer station. Also in accordance with the method or system for controlling an electrophotographic printer or copier that has at least two developer stations, during a print operation the print data is used to determine which developer stations are needed for printing of the data. In the event it is established that a developer station was not needed or will not be needed, the developer station is shifted into a standby state in which at least one part of mechanical actuators of the developer station is stopped.

摘要:
In a printing or copying device which has one or several exchangeable part units with a modular assembly, the part unit to be identified has an identification device with a non-volatile memory for storing function-relevant operating data of the part unit, said operating data being allocated to operating states. The part unit also has a communication interface for detachably connecting the identification device to a process control device of the printing or copying device.
