Tricks for freeing cartridges from air bubbles
Does somebody know some trick for getting rid of air bubbles introduced by
ink refilling? I've always sucked some ink from noddles and made several cleaning cycles but I still get white rows il barbi |

I have used a plastic bag inside a sock or you could just go outside. I have found the centrifuge method was not 100% successful for me. I switched to bleeding with the cart upside down. The device that fills from the noddles(sic) is probably best if one can find and afford one. |

Tricks for freeing cartridges from air bubbles
It depends a lot on which printer(s) you are speaking of.
Cartridges which have batting or sponges in them are the worst for this, as they can trap air (and some do so intentionally to make them difficult to refill) In fact some manufacturers put soap in the inks to make the foam not accept the new ink. If the last is the case, sometimes putting a few drops of alcohol into the ink will break these soap bubbles down. You can use a negative vacuum method for refilling, where you suck most of the air out of the cartridge and then introduce the ink which is pulled in to replace the vacuum. There are specialized devices made for this on the internet. Some people use an old sock or salad spinner to have what when I was young was referred to as centrifugal force (sorry don't want to get into a long argument about false forces and inertia... not today, at least). Anyway, if you point the ink outlet toward the outside (or course, make sure it is well sealed! before spinning) the ink will tend to be pushed toward the outlet and the air will tend to displaced and end up on the top of the cartridge which is where it should be. You can also store the cartridge on the ink outlet so the ink naturally tries to displace the air, or you can just tap downward at the ink outlet area the sealed cartridge on something to try to dislodge the air pockets. Lastly, most refillables today use spongeless cartridges which use a labyrinth of channels and chambers to hold the ink from leaking out. Some are easy to refill if so designed, usually using two access holes that need to be resealed well before storing, other (like those made by the printer manufacturers) will probably use a system of channels which have to be filled in the correct order etc to get a full cartridge of ink. Check the web to see who is supplying specific instructions.

Maybe leave it (the cartridge, not the whole printer) on top of your washing machine during the spin cycle, a bit violent, or use one of those sonic vibrating toothbrushes for a minute or two to see if it persuades the air bubbles to rise? Of course it could just turn it all to froth and make it worse! Just leaving it (the right way up) overnight might help things along. -- Richard C |

... It depends a lot on which printer(s) you are speaking of. my printer is a multifunctional HPF380 with ink cartridges HP21 (black) and HP22(color), can you suggest some adhoc procedure? il barbi |

Tricks for freeing cartridges from air bubbles
Well, for one thing, the HP cartridges you speak of have the head incorporated in the cartridge. That probably means you need to protect the head during any procedures to eliminate the air bubbles. I'll leave the rest to people who regularly refill these types of cartridges. I'm sure there are some tricks. Finally, Google is getting really good at finding these kinds of things. If you put something like: Refilling HP21 & HP22 cartridges into the search area, I'd bet you'll get something helpful. I just looked and there are utube videos and more.

Not much to play with there. If you over fill the black a bit you can just let it drain while if you over fill the color you can turn the whole thing into a dark green cart. |

The refill procedure is the same. I use the Inktec refill kit holder and syringe to remove any air that might be there. Look on Youtube for videos on the HPI-0005D and HPI-0006c refill procedures with this equipment. I have the best luck refilling before the carts run out of ink. That is what seems to draw the air into the passages leading to the printhead. Also, if you wait too long after running out some ink may dry within those passages, forming a clog that won't clear out through the nozzle. I've also had better luck with black than tricolor, and I've had better luck refilling original rather than "remanufactured" carts. My own theory, which could easily be completely wrong, is that "remanufactured" carts are likely to have been run out of one color or another and slightly damaged in a way that might not show up until they are refilled and used a while.
