eliminate air from entering cartridge?

[williamhoo]

Hi,

I am very new at this stuff. So, please excuse if any of my question seems to be stupid.

Here's the question:

As far as i know, it is possible that when injecting the needle into the cartridge for refill is possible for the air bubble to enter. Also, when removing the needle after refill can allow the air bubble to enter

So, let say that i create a machine that has a door where i can put a cartridge inside for the machine to process the refill of ink. But my machine, let say that i put a cartridge inside(without injecting the needle when the air is still present), then i close the door and turn on the vacuum. after turning on the vacuum to the satisfying level where it's not possible for the air to go into the cartridge, i then order the so-called robot to inject the needle into cartridge(no air present) and then after injecting, i can then fill it with the ink(of course still no air is present), and after that, i remove the needle in a no air present situation. so, after all that happen, i can then open the door to take the cartridge for it to be used.

This situation, is there any flaw to this? let say i manage to create this, will there a guarantee for the ink to be 100% ready use; in other words, the customer would enjoy full use of the ink in the cartridge (still talking about tackling the air bubble situation, and not about the need for resetting the chip)?

Thank You

If you are going to use a vacuum chamber and you are filling single-color cartridges, you don't need a needle. See my article here for details:

You can also use the vacuum chamber described in that article to fill multi-color cartriges but I have never done that and am not familiar with the process. You might find out more information at:

Thanks for the quick reply ghwellsjr.

I'm sorry for not saying clearly. i am thinking about opening a refill inkjet business. So, i was thinking of making a machine as mentioned above. So, if anyone knows, will it eliminate the air bubble if the process of inserting and ejecting the needle in a vacuum area(no air present) will help eliminate 100% air bubble. Also, i would like to know if there is any consequences for doing so.

Thank you very much.
