I am trying to populate the nozzles in an ink cartridge with ink. The 45 micron holes have tape over the outside of the nozzles and I need to populate all 512 nozzles with ink from the inside.

 

I was thinking of creating a vacuum inside the cartridge i.e. taking all of the air out of the cartridge and then releasing ink in. and hoping that these micro holes then replaced the vacuum with ink but I am not sure if this will work due to the surface tension of the ink.

 

Does anyone have any ideas how I could do this please?

Um, I doubt you have the necessary equipment, but if it was possible for you to make a vacuum inside the hole, then I don't see any reason the ink wouldn't fill fill it? If it was indeed a vacuum inside the hole, introducing the ink would do one of two things; either fall into the hole, and fill it, or simple cover the hole, and then it would be stuck over the hole because the pressure inside is lower than that of outside, which would mean the outer air-pressure would press down on the ink.

 

Why are you doing this anyway?
