Troubleshooting Inkjet Printers: Tackling the Air Bubble Challenge

In the realm of inkjet printers, a persistent challenge that users encounter is the formation of air bubbles in the supply lines, impacting the printing process. This discussion sheds light on a potential culprit and offers practical solutions to mitigate the issue.

The Air Bubble Conundrum: Storage Methods Matter

One user suggests a compelling hypothesis: the storage method of ink may play a pivotal role in the formation of air bubbles. According to this theory, refrigerating ink could lead to the gradual dissolution of more air, which may later manifest as slow-moving bubbles when the ink returns to room temperature.

To counter this, the recommendation is to allow the ink to reach room temperature or slightly higher before refilling, coupled with vigorous shaking to expedite equilibration. The idea is to facilitate the escape of dissolved air, preventing the persistence of supersaturation over an extended period.

Alternative Approach: Degasification through Heat

A user proposes an alternative method to counter air bubbles: degassing the ink by slightly heating it below the boiling point and then cooling it before refilling. However, caution is advised, emphasizing the need for testing beforehand due to potential concerns about ink stability and the loss of other volatiles.

Warming and Shaking: A Lab-Tested Technique

In the spirit of problem-solving, the discussion delves into the potential efficacy of warming and shaking the ink. Drawing inspiration from standard laboratory methods involving bubbling nitrogen through a liquid to remove CO2, the idea is to utilize the increased surface area generated by bubbles to facilitate gas exchange. While not personally tested, this method stands as a plausible approach to reduce dissolved air.

Vacuum as a Potential Solution: Lowering Boiling Point

The conversation briefly touches upon the possibility of using a vacuum to lower the boiling point of the liquid. While this may prevent heat degradation of the ink, it is acknowledged that the method might not fully address the issue of other volatiles escaping from the ink.
