Device for non-contaminating changing of a toner container in a toner conveying means of a non-mechanical printer or copier means

A system for the transfer of toner from a toner transport container into a developer station of a non-mechanical printer ro copier means, comprising:

• a suction nozzle,
• a guide means mounting said suction nozzle in vertically displaceable fashion,
• a toner-tight protective sheath mounted about said suction nozzle,
• a pipe line connecting said suction nozzle in communication with the developer station,
• an adapter being connected to the protective sheath and being releasably fastenable to provide a releasable, toner-tight fastening to the filling and emptying opening o the toner container, said suction nozzle passing through said adapter into the eh toner container for emptying the toner container;
• a holding mechanism mounted below said guide means and constructed to hold the toner container in a position that permits the suction nozzle to move into the toner container on the basis of its own weight;
• the toner container comprise a funnel-shaped floor that forms a lowest collecting region for toner in the toner container, a filling and emptying opening and the collecting region of the toner container are arranged relative to one another such that, given holding of the toner container the holding mechanism in a removal position wherein the collecting region is at a lowest region of the toner container, the suction nozzle is expendable into the collecting region.
