Abstract
(DE)
Beschrieben wird ein Verfahren zur Regelung eines eletrografischen Druck- oder Kopierprozesses, bei dem zu druckende Informationen als Tonerzwischenbild auf einem Zwischenbildträger (4, 122, 130, 136, 144) erzeugt werden und später in einer Umdruckzone (5, 132, 146) von einer Umdruck-Oberfläche (130, 144) auf einen Aufzeichnungsträger (2, 114) übertragen werden. Dabei wird auf einem elektrografischen Zwischenbildträger (4, 130, 144) eine Tonermarke erzeugt, die Tonermarke auf dem Zwischenbildträger (4, 122, 136) zumindest bereichsweise abgetastet und die Tonermarke anschließend vom Zwischenbilträger (4, 122, 136) wieder entfernt. Mit dem gemessenen Wert wird die Tonerkonzentration in einer Entwicklerstation (8) geregelt. Der Übertrag des Tonerzwischenbilds von der Umdruck-Oberfläche (130, 144) auf den Aufzeichnungsträger (2, 114) wird im Zeitraum zwischen der Erzeugung und der Entfernung der Tonermarke zumindest zeitweise verhindert. Durch die Erfindung werden insbesondere zwei Betriebszustände geschaffen.
(EN)
The invention relates to a method for adjusting an electrographic printing or copying process. Information to be printed is generated as a toner intermediate image on a support for intermediate images (4, 122, 130, 136, 144) and is subsequently transmitted from a reprinting surface (130, 144) to a recording medium (2, 114) in a reprinting zone (5, 132, 146). A toner mark is produced on a electrographic support for intermediate images (4, 130, 144). Said toner mark is at least partially scanned on the support for intermediate images (4, 122, 136) and then removed from the support for intermediate images (4, 122, 136). The toner concentration is adjusted in a developing station (8) by means of the measured value. Transfer of the toner intermediate image from the reprinting surface (130, 144) to the recording medium (2, 114) is at least temporarily prevented in the period between the production and the removal of the toner mark. The invention especially provides two operating states.
(FR)
L'invention concerne un procédé et un dispositif pour réguler un procédé d'impression ou de duplication électrographique. Selon l'invention, les informations à imprimer sont produites sous la forme d'une image intermédiaire de toner sur un support d'image intermédiaire (4, 122, 130, 136, 144) puis sont transférées ultérieurement, dans une zone de duplication (5, 132, 146), d'une surface de duplication (130, 144) vers un support d'impression (2, 114). Une marque de toner est produite sur le support d'image intermédiaire électrographique (4, 130, 144), puis la marque de toner sur le support d'image intermédiaire (4, 122, 136) est balayée au moins partiellement et retirée ensuite du support d'image intermédiaire (4, 122, 136). La valeur mesurée est utilisée pour réguler la concentration de toner dans une station de développement (8). Le transfert de la surface de duplication (130, 144) sur le support d'impression (2, 144) est empêché au moins en partie pendant l'intervalle de temps compris entre la production et le retrait de la marque de toner. L'invention permet de créer au moins deux états de fonctionnement.
