Abstract

The present invention pertains to an ink reservoir for an inkjet printer, having a chamber that can be filled with ink, in the underside of which is an ink outlet with an ink discharge opening. In order to make the delivery of the ink uniform and independent of fluid movements of the ink contained therein, the invention suggests that the ink outlet be configured in a siphon-like fashion, having a segment that extends from the ink discharge opening into the interior of the chamber and that makes a transition via a deflection bend w into an intake opening that is directed towards the chamber bottom from inside.
