I did a refill of the 4 carts a few days ago and had to do several cleanings, and even a deep cleaning for BK before I had a reasonably clean output again.@rrreinig : Don’t be surprised at all if, after refill, the first nozzle check is bad. It happens very often. In my case it’s usually banding in the lower rows ( mostly the yellows and sometimes magentas). You need to perform an additional cleaning cycle to get a normal test. It’s also preferably to print quite a bit immediately after refilling, in order to stabilize the internal pressure. As @palombian said, these cartridges are totally different from the sponge based Pixmas. It takes a while to get used to their peculiar behavior.
If you didn't seal the ink outlet it is normal the cartridge leaks when inserting.I have just changed over all my OEM inks to HP ink and the printer didn’t take to it very well, I too had to do several cleaning cycles to get a good nozzle check, then had to run 10 or 15 test sheets to stop the black leak from appearing on the top of each sheet, must have over filled it…
All the colours look ok dough, but I want to wait a week or so for everything to settle down to see how this ink behaves, or will I have to run a cleaning cycle after a few days inactivity to get a decent print after the ink has settled..
I have fitted ARC chips on all the OEM carts after the refill and each are showing the carts full, but I’m keeping the used OEM chips in case of any unusual errors..
