Problems solved by technology

[0004] Additionally, when inks contain volatile components, the ink at the nozzle may lose these components, in some cases causing the remaining components of the ink to form a semi-solid skin at the nozzle
A buildup of semi-solid skin or solid deposits can interfere with ink jetting from the nozzles, reducing print quality or even preventing ink from jetting from one or more nozzles
Also, using UV-curable inks can lead to buildup, which can eventually clog the nozzles, reducing print quality

Abstract

The present disclosure relates to systems and methods for non-contact maintenance of inkjet printheads. In particular, the present disclosure relates to systems and methods for removing purged ink and other debris from one or more inkjet printheads without contacting the nozzle plate with mechanical devices, such as by selectively attaching the printheads to Move over discrete cleaning stations for wiping and unit operations involving vacuum and target cleaning.

Description

Background technique [0001] The present disclosure relates to apparatus, systems, and methods for non-contact maintenance of inkjet printheads. In particular, the present disclosure relates to apparatus, systems, and methods for removing purged ink and debris from an inkjet printhead and its surroundings without contacting a nozzle plate with a mechanical device. [0002] Inkjet printheads require periodic cleaning of the print nozzles to remove buildup (solid deposits and debris) on the nozzles, remove air bubbles, remove pooled liquids, and otherwise maintain print quality. Cleaning the printhead is an inherent part of the inkjet printing process, for example in some industrial settings the printhead is cleaned every two minutes. The frequency of cleaning depends on the specific application in which the printhead is used. Typically, cleaning can also be done by moving the printhead to the side of the printer for access, and cleaning the printhead manually or with a wiper. ...
