Abstract

A cleaning head includes an end face that faces an inkjet print head to be cleaned. A supply opening and a discharge opening are spaced apart on the end face. A supply channel carries cleaning fluid to the supply opening. The discharge opening receives cleaning fluid that is to be conveyed away after having been emitted through the supply opening. The cleaning head emits a cleaning fluid jet through the supply opening with the cleaning fluid jet being emitted in a direction having a component that is directed towards the discharge opening so that the cleaning fluid can be conveyed away by suction through the discharge opening.
