Suction device for cleaning a nozzle surface of a print head

摘要

A suction device is provided for cleaning a nozzle surface of a print head. The suction device comprises a suction surface and a spacer, whereby the spacer is provided with a spacer channel, the spacer channel comprising a spacer opening at an outer surface of the spacer and the spacer channel being operatively coupled to an air flow source. The spacer is configured for positioning the suction surface at a predetermined distance from the nozzle surface for providing a suction gap. The suction device is configured to provide in operation an air flow through the suction gap, along the nozzle surface and into the suction channel. An air flow may be provided through the spacer channel of the spacer in order to clean an area of the nozzle surface of the print head.
