Abstract (en)
[origin: EP0711668A2] The refilling system for the ink cartridge, of an ink jet printer, has a pump with a reversible flow direction. An electronic control gives a fully automatic control of the refilling operation. It activates the pump to transfer ink from the ink tank to the supply zone, until a given level is achieved. It then reverses the pump, to cancel the feed pressure and, if required, develop an underpressure in the ink supply station. The printing head is positioned in the mounting with the jet plate open upwards in the filling position. The pipe connections are flexible tubes pref. of silicon, PTFE or polyethylene.
