摘要

Print head (1) comprises a print component (2) with jets (13) arranged in a row, a print medium reservoir (3) and a guide plate (4) with a fluid flow channel for the ink from the reservoir. The jets are directed upwards, while a run-off channel (9) surrounds the reservoir and the guide plate. The ink caught in the run-off channel collects in an intermediate tank (10) and is then transported via a flow-off line (11) to a collection tank (12). Pressure to the ink reservoir is supplied via compressed air.
