Initially ink comes out but then fades even though cartridge is full

This is a HP 65 cartridge refilled. Only the blue fades. I've soaked the bottom of the cartridge in alcohol and hit water. After a while it will again momentarily print but then fade. Is this a physical or electrical issue?

Did you solve it? How old was the ink cartridge. I've had old hp ink cartridges (a couple years beyond the expiry date) do something similar.

IDK if I'm still dealing with this particular cartridge but I deal with this issue with several cartridges.

Would you know more about this issue and how to solve it?

I'm thinking as I've read before it has to do with air pressure or something air related in the cartridge. Like it either needs some atmospheric or vacuum pressure, or something like that.

I want to learn what this is about and how to maintain proper pressure in there.
