Abstract: In a method and a device to sort pixel data in a print data stream, a data sorting memory is used configured so that it can be written per column and read per row. The pixel data are entered per column into the data sorting memory in the order of the incoming print data stream. Via the per-row readout the pixel data are re-sorted into an order suitable to control the print head. The sorting can thereby take place in only one write process and one read process.

Abstract: In a method to convert color-describing input print data suitable for graphical output with aid of an output apparatus into color-describing output print data, color proportions, defined by the input print data, of at least one region to be inked with at least two color separations, are determined, and a color space value to be generated with aid of the color separations is determined. An association rule is determined to convert the input print data into the output print data while retaining the color space value.

The input print data is converted into the output print data with aid of the determined association rule.

Abstract: In a method to remove toner deposits on a surface of a cleaning element, electrically charged toner particles are transferred from a transfer element surface to a photoconductor. On the cleaning element, untransferred, electrically charged toner particles as residual toner from the transfer element surface are received. Electrically charged toner particles on the cleaning element are directed past an electrode arrangement arranged at a distance from the surface of the cleaning element. An alternating electrical field is generated which acts on the toner particles to loosen them. The toner particles remaining on the surface of the cleaning element are brought into contact with a mixture of carrier particles and toner particles during further transport along a transport direction of the cleaning element.

Abstract: In a method or system for generation of a toner image layer with a preset layer thickness on a surface of a photoconductor, the two-component mixture of electrically charged toner particles and carrier particles is directed on an auto-surface of a roller adjacent a surface of an applicator element to be inked. At least a portion of the toner particles is transferred onto the surface of the applicator element. An electrical field is generated that exerts at least one force on a portion of the electrically charged toner particles between the roller and the applicator element. A strength of the electrical field is varied to adjust a layer thickness of a layer of the toner particles transferred onto the surface of the applicator element and thus to adjust a thickness of the toner image layer on the photoconductor. A measurement arrangement detects a thickness of at least one region of the toner image layer inked on the surface of the photoconductor as a real value.

Abstract: A recording medium is moved to a transfer printing station and print images are transfer-printed. The recording medium is transported to a fixing station. A print stop is initiated whereby the recording medium is halted, a further transfer printing is prevented, and a fixing is deactivated. It is checked whether a transfer-printed but unfixed page is still located in the printing apparatus. If so, a warning notification is automatically generated. A query is made as to whether an operating command has been input. If so, it is checked whether the unfixed page would also be output unfixed. If no, the operating command is executed. If yes, the print stop is automatically maintained. It is also inspected as to whether the unfixed page would be output upon execution of an additional operating command. If no, the additional operating command is executed. If yes, an error message is automatically generated.
