Problems ahead for HP refillers

[Grazer5]

HP's applied for a patent that makes a cartridge unrefillable. At least that's what I think it means.

I can't imagine any reason why this couldn't be refilled.

For Canon potential issues as well.

Can I ask since when re manufacturers in china care about any patents ? Or do you guys know any re manufacturers in Europe really?

 

[Ink stained Fingers]

it's not just about the remanufacturers, they may find a way to bypass constructional tricks, but it is as well
possible to block imports into the EU due to patent infringement, and then the importer/dealer would be sued by Canon/HP etc. That approach has been used in various cases in the past, in the EU , and the US.

It's a shame Canon, HP want to go that extra mile to stop refilling.

We will just have to double our efforts so that doesn’t happen any time soon..

I also think they could be refilled. Here is the drawing from the patent application, with the cartridge outline marked in red and a needle marked in green.

I think that at least two methods should work for refilling.

1. Seal the outlet and insert a sharp needle through a hole drilled above the ink out let chamber and inject ink. Ink should fill the ink outlet chamber and fill the wick material marked 66 (or 73?) and continue to fill the sponge at the top.

2. Turn the cartridge upside down and use the Freedom Refill method. As this is a vacuum refill method, the wick material marked 66 (or 73?) should be re-saturated with ink.

Does anybody know if these cartridges have been introduced yet and what type number they might be or what printers they are used in?

Yes, I'll betya they can be Freedom filled without even blinking.

Way to go @ThrillaMozilla, that’s the way to treat these blaggards...
