摘要:
Charge patterns of the images to be printed are produced on a photoconductive strip (OPC) and transformed into toner images using toner, and the toner images are transferred to a transfer strip (TFB) from which they are pressed onto an end image carrier (AT) once the end image carrier has been pivoted onto the transfer strip. The time of the production of the charge pattern on the photoconductive strip (OPC) and/or the transfer of the toner images to the transfer strip (TFB) is set such that the vibrations and disturbances caused on the transfer strip (TFB) and the photoconductive strip (OPC) by the pivoting of the end image carrier (AT) onto or off the transfer strip (TFB) do not have any influence on the production of the charge patterns on the photoconductive strip (OPC) and/or on the transfer of the toner images from the photoconductive strip (OPC) to the transfer strip (TFB).

The invention relates to a method and arrangement for inking up an applicator element (14) of an electrophotographic printer or copier. A two-component mixture, which is comprised of electrically charged toner particles and of ferromagnetic particles and which adheres to the outer surface of a roller (16), is moved past a surface of an applicator element (14) to be inked up. When the two-component mixture is moved past, at least a portion of the toner particles contained in the two-component mixture is transferred to the surface of the applicator element (14) to be inked up. An electrical field is generated that acts at least upon the portion of the two-component mixture located between the surface of the roller (16) and the surface of the applicator element (14) to be inked up. The strength of the electrical field can be controlled with the aid of a control unit so that the transferred toner particles produce a preset layer thickness on the surface to be inked up.

The invention relates to a method for producing a developer mixture in a developer station (14, 16/1 16/5) of an electrographic printing device. According to said method, the developer station (14, 16/1 16/5) is simultaneously filled with ferromagnetic carrier particles and toner. In the event of a malfunction, the filling process is continued, using the last detected quantity of carrier particles and/or toner, in a predetermined process step.

The invention describes a method and a device for removing toner deposits from the surface of a cleaning element (36). Electrically charged toner particles (12) are exposed to the alternating electric field of an electrode arrangement (44) which loosens the toner particles (12). A mixture of carrier particles (14) and toner particles (12) transports the loosened toner particles away.

The invention relates to a method, a computer program and a print system for trapping print data having a plurality of objects. According to the invention, the objects are transferred one by one to a pixel file while at the same time carrying out trapping. The method can be carried out in real time without causing any delay in the printing process. It can therefore be integrated into a print data flow for high-speed electrographic printers.

In order to replenish toner in the developer stations (EWS) of an electrographic printing device, toner reservoirs (TF) are connected to the developer stations (EWS) via toner transport channels, e.g. feed channels. The invention relates to a device that is controlled by a feed time manager and that transports the toner from the toner reservoirs (TF) to the developer stations (EWS). When toner is needed, the developer stations issue feed requests to the feed manager. The feed manager coordinates the feed requests of the developer stations (EWS) and accords feed permission to the developer stations (EWS) especially in a clocked manner.

The invention on relates to a method and a device for archiving printed images. At least one printed image produced using at least one printing or copying system (18, 19a, 19b) is acquired by means of an acquisition unit (26). Image data that correspond to the acquired printed image are produced and are archived in an archive (32).

A toner supply container has a toner bottle and a cover, in which the toner bottle is fastened. The cover (DE) comprises a cover upper part (1) for receiving the toner bottle (TF) and a cover lower part (2) which can be displaced and locked in a guide (22) in the cover upper part (1) for closing the outlet opening (18) of the toner bottle (TF). A first locking means (4) is provided in the cover upper part (1), which first locking means (4) locks the cover lower part (2) in the guide (22) in the cover upper part (1), as long as the toner supply container (TV) is not placed on the toner receiving container (TA). A slide (SE) provides an unlocking means (3) which unlocks the first locking means when the cover (DE) is placed onto the toner receiving container (TA), with the result that the cover lower part (1) can be moved together with the slide (SE).

The invention relates to a method and to a device for scanning an image, wherein a source image is detected by means of a colour sensor. The colour sensor comprises several line arrays which are formed, respectively, to detect a specific colour. Colour separations are generated by means of said line arrays. According to the invention, separate FIR partial filters are applied to the colour separations without having to mix said colour separations prior to a complete colour image. Mixing of the image pixels occurs automatically during filtering. As a result, the several line arrays can scan the image points of the source image simultaneously and said image points can be formed in real time on image pixels of a target image.

The invention relates to a method for generating and/or processing a ressource-based document data stream with which the output of at least one document on an output medium, particularly a recording carrier, can be controlled. The document data stream which contains ressource reference data related to a colour management ressource and medium reference data related to the output medium is configured in such a manner that the ressource reference data and the media reference data are logically interconnected so that a change of a relation on an output medium within the document data stream causes automatically a change in the relation to a colour management ressource.
