Hi everyone, got a 7600 cheap that has ultrachrome ink. Most everything on the control panel got 5 stars. Did multiple head cleanings, a power cleaning, and puddling of the cap and paper towel trick on the print head. I've only got one black working so far. I can see that the yellow line is clogged, and I'm guessing the rest may be as well and they are just harder to see. So any suggestions on clearing the lines. There are a lot of options out there, do I pay $200+ for cartridges with special fluid or just get refillables for around $100 and fill them with simple green. I don't know if the original users switched ink types, so there could be gelling instead of crystaling in there. Thanks.
