Inkjet printing systems and methods for controlled, non-imaging inkjet purging

An inkjet printing system comprising:

• a media transport module comprising a transport belt and configured to transport a print media substrate through a print zone of the inkjet printing system, wherein the media transport module comprises a low-stick purge device disposed on and/or embedded in the transport belt;
• an inkjet printhead comprising a plurality of inkjet nozzles and configured to eject ink droplets from the plurality of inkjet nozzles in the print zone;
• and
• a print engine operatively connected to the media transport module and the inkjet printhead, wherein the print engine comprises one or more processors in communication with a non-transitory computer-readable storage medium having stored thereon instructions that, when executed by the one or more processors, cause the inkjet printing system to perform the following operations:
• detect a position of a transport belt of the media transport module;
• determine, based on the detected position of the transport belt, a location of the low-stick purge device of the media transport module;
• and
• eject, from a first inkjet nozzle of the plurality of inkjet nozzles, one or more ink droplets based on the determined location of the low-stick purge device of the media transport module, wherein the one or more ink droplets are ejected onto the low-stick purge device as the low-stick purge device moves through the print zone of the inkjet printing system.

A media transport module for use in an inkjet printing system, the media transport module comprising:

• a transport belt comprising a plurality of vacuum belt holes, wherein the transport belt is configured to transport a print media substrate through a print zone of the inkjet printing system;
• and
• a low-stick purge device having a surface energy less than a surface energy of the transport belt;
• wherein the low-stick purge device of the media transport module does not include any of the plurality of vacuum belt holes.
