Abstract
A continuous inkjet printer has an ink circuit comprising an ink tank, an ink pump and a Venture suction device. The Venturi is used to suck an extra solvent or ink as required. However, if the ink tank is empty, no ink can be pumped through the Venture and so it will not develop suction and thus, cannot be used to suck in an initial supply of ink to an empty tank. A removable ink container may be connected to the ink tank or elsewhere in the ink circuit, for example, between the Venturi outlet and the pump inlet. Compressing the ink container manually will force ink into the ink circuit. When enough ink has been added, the pump will drive ink through the Venturi and suction will be generated.
