Method and System For Detecting and Classifying Air Pockets within Ink Supply Lines

A system comprising:

• a print device comprising an ink line configured to transport ink;
• a first sensor configured to measure capacitance of a first portion of the ink line;
• a processor;
• and
• a non-transitory computer-readable storage medium comprising programming instructions that are configured to cause the processor to:
• receive sensor data from the first sensor,
• monitor, based on the sensor data, capacitance of the first portion of the ink line, and
• identify an air pocket in the ink line in response to detecting a decrease in the capacitance of the first portion of the ink line.
