ABSTRACT:
A tank system for cold fixing a toner powder on a paper as it is conducted through a fixing station of a non-mechanical high speed printing and copying device characterized by the printed paper being conducted through an atmosphere enriched with the vapor of a fixing agent. The tank system includes an injection tank which is connected to a replaceable feed container containing the agent with the injection tank being controlled to inject the agent into the fixing station to maintain the desired concentration of the vapor. The system also includes a recovery device including a water separator which separates condensed fixing agent from the water of the condensate. The system also includes a buffer tank which receives the recovered fixing agent, a pressure tank which is coupled to the buffer tank and has an outlet with a valve connected to the supply system, and an air pump to supply compressed air to the pressure tank to return any agent in the tank into the feed container and/or into the injection tank.
