摘要： Systems and methods for industrial printing, e.g., using drop-on-demand (DOD) inkjet print heads, include, in at least one aspect, a printing device including: a print head including a print engine, including multiple nozzles, and circuitry to selectively eject ink through the multiple nozzles to form an image on a moving substrate, and to purge the ink through the multiple nozzles; and a printhead enclosure having an opening in front of the multiple nozzles to allow the selectively ejected ink to pass through the opening when the selectively ejected ink is ejected toward the moving substrate; wherein the printhead enclosure includes a hole placed away from the multiple nozzles; and wherein the printhead enclosure is configured to direct the ink that is purged through the multiple nozzles along an inside surface of the printhead enclosure to the hole through which the ink flows and exits the printhead enclosure.

摘要： Systems and methods for industrial printing, e.g., using drop-on-demand (DOD) inkjet print heads, include, in at least one aspect, a printing device including: a print head configured to selectively eject liquid through nozzles to form an image on a moving substrate; and a printhead enclosure configured to contain a pressurized airspace at least in front of the nozzles; wherein the printhead enclosure includes a slot that aligns with the nozzles to allow the selectively ejected liquid to pass through the slot when the selectively ejected liquid is ejected toward the moving substrate; and wherein the printhead enclosure is configured to contain the pressurized airspace and cause airflow through the slot at a flow rate that prevents dust and debris from entering the slot while the selectively ejected liquid passes through the slot and the airflow without a direction of the selectively ejected liquid being impeded by the airflow.
