Late to the party, just back from vacation.
The deal at PROCAM seems to be over??? They show the PRO-10 out of stock on line, and there's no place to click and order.
Are you sure? I have very good water too. I think it has mostly to do with pH, but it could vary from time to time. I strongly suggest that you make a careful test. I could easily see the flocculation by mixing a couple of drops and observing with a 10x magnifier.
There's one thing I think I do not recommend: tap water. I have seen recommendations to just put a print head under running tap water, but here's the rub:
tap water can cause pigment ink to flocculate.
I was experimenting with cleaning fluids, and mixed a drop of black pigment ink with a...
Thanks for looking up all those discussions. I guess you're right that Canon seals them hermetically. I had forgotten that.
But that doesn't mean that home users need to seal the vent for storage. If the vent had not been sealed when Turbguy opened the ink port, it wouldn't have leaked, and...
I don't think so. They're never bulging, and they don't go "poof" when I open them.
I just use Scotch tape for storage, to minimize evaporation. It won't hold pressure, so you don't need to worry about that, and it comes off easily. Sealing the vent is not critical, in my opinion.
He used C and M instead of PC and PM. I'm not sure what's wrong with GY, but perhaps the wrong ink has been used there as well?? There may be something funny about black too. I don't know what the solid bars are supposed to be.
I guess I don't know what you're trying to do. What kind of printer do you have or want to get? And what kind of ink and supply system do you want to use? ???
If you're trying to find Linux drivers for a Canon printer, my answer applies.
:celebrateAardenburg is back big-time, testing some of your favorite ink in your favorite printers. And they still need support to complete the work.
