More Information
Summary:In one embodiment, a non-contact print head cleaning device includes an elongated cavity underlying a print head and a vacuum port connected to the elongated cavity and generating a low pressure in the elongated cavity. A slot in a wall of the elongated cavity has a geometry that varies along its length to produce an airflow with a substantially uniform velocity into the slot. The airflow sucks contaminants off the print head into the slot. A method for non-contact print head cleaning is also provided.
