Abstract
The on-site assembly work can thus be minimized with a device for supplying ink to at least one compartment of an ink reservoir of a printer having at least one supply channel which extends beyond the respective ink reservoir area and is provided with outlet orifices assigned to the ink reservoir, the supply channel being connected to an ink supply line which is provided with a valve arrangement, and having at least one filling level sensor whose signals can be processed by means of a control unit to yield switching commands for an operating device assigned to the valve arrangement; this is accomplished by providing a multifunction rail that spans the respective ink reservoir area, having at least the supply channel with the respective outlet orifices and at least one insertion channel which is open at the bottom to accommodate at least one filling level sensor and being provided with covers at the ends, with at least one cover having at least one end area of an ink supply line and the valve arrangement assigned to it with the respective operating device.
