Abstract:
This invention relates to a process for cleaning an inkjet printing head which has nozzle openings and ink channels which lead to them, in which electrical drive elements for ejecting ink out of the nozzle openings are located, in which the nozzle openings and the ink channels are forcibly flushed with cleaning liquid. To achieve improved cleaning action more gently and less expensively, the drive elements are triggered in an oscillating manner during the forced flushing with cleaning liquid. A cleaning device for carrying out this process is also disclosed.
