Definitions

  • the invention relates to a device according to the preamble of patent claim 1.
  • charge images are recorded on a recording medium e.g. produced directly on an intermediate carrier (photoconductor drum) or directly on special paper and then colored with a black powder (toner) in a developer station.
  • a recording medium e.g. produced directly on an intermediate carrier (photoconductor drum) or directly on special paper and then colored with a black powder (toner) in a developer station.
  • an intermediate carrier photoconductor drum
  • this toner image is then transferred to normal paper and fixed on it
  • a two-component developer is used for development, which consists of ferromagnetic carrier particles and the color-carrying toner particles.
  • the developer is guided past the charge image on the intermediate carrier by means of a magnetic brush arrangement, to which the toner sticks due to electrostatic forces.
  • An electrophotographic copier that develops charge images according to the specified principle is e.g. known from DE-AS 21 26 667.
  • the toner concentration in the developer mixture of the developer station decreases continuously. It is therefore necessary to continuously add new toner to the developer mixture. Since the toner consumption per unit of time is very high in the case of fast copying machines and high-performance data printers, a spacious toner reservoir is used in such machines in order to avoid downtimes by refilling the toner. When this toner reservoir is empty, the toner, which is usually supplied in handy containers, is filled into the reservoir. It is important to fill the toner from the container into the storage container in such a way that no toner is spilled and the environment is thereby contaminated.
  • a device for filling and sieving toner from a container into a toner storage container is known.
  • the toner located in a transport container namely a toner bottle
  • a storage container in that the toner bottle is slipped into a filling opening of the storage container.
  • a sieve basket which is closed off from the storage container by a sieve and which is connected to an electrical vibrating device which can be triggered if necessary.
  • the vibrating device is triggered by opening the lid that closes the filling opening.
  • the object of the invention is to design a toner container of the type mentioned in the introduction in such a way that the toner can easily be used in non-mechanical printing or copying devices can be supplied without escaping toner can pollute the environment.
  • the toner is removed from the toner container with the aid of a suction nozzle which is arranged within a protective cover which is connected to a filling and emptying opening of the toner container via an adapter, no toner dust can contaminate the surroundings.
  • a safety device ensures that the proboscis can only dip into the toner container for suction when there is a dust-proof connection between the filling and emptying opening of the toner container and the adapter.
  • the same safety device also prevents the closure from loosening when the proboscis is immersed.
  • the toner containers are advantageously delivered with a sealed filling and emptying opening.
  • the adapter is designed so that only when the toner container is connected to the adapter does the adapter pierce the sealing film via a cutting device. Spilling of toner when inserting the toner container into the corresponding receiving device in the printing device is therefore not possible.
  • the changing of the toner container is facilitated in that the container receiving the toner container is designed to be pivotable out of the printer.

Abstract

Dans un système de transfert (19) situé dans l'imprimante, un bec aspirant qui communique via une canalisation avec l'unite de développement est agencé de manière déplaçable verticalement à l'intérieur d'une gaine de protection (28) étanche au toner. Le système de transfert (19) comporte à son extrémité inférieure un adaptateur destiné au raccordement du réservoir de toner (10). Lors du remplacement, on fait pivoter le nouveau réservoir (10), par l'intermédiaire d'un dispositif porteur (32), vers l'adaptateur et on le raccorde avec celui-ci. Un système de coupe (31) adjoint à l'adaptateur perce alors un film de scellement dudit réservoir (10). Pour la vidange, le tube aspirant est immergé verticalement dans le réservoir de toner (10) dont le fond présente une configuration en entonnoir servant de région de stockage de toner.
