We have a HP printer that we have been using for about a couple of years now. I bought a ink refill kit (color) from Office Depot a few months ago and refilled the color cartridge. It worked fine for a few weeks. I noticed over the weekend that it quit printing red (any color that needs magenta). So, I refilled the cartridge one more time and tried, but no use. I refilled it once again, still no use. When I press a piece of paper against the print head, I do see all three colors on the paper. I can actually see all three colors slightly oozing out of the head. But the printer prints only colors pertaining to yellow and blue, but nothing that involves magenta. I started suspecting the printer. I went out and bought a brand new color cartridge and tried in the printer. Now, everything works fine. My question to you is, do you know the reason for the behavior of my old cartridge? Thank you very much for your time.
Lessons learned: 1) Do not buy "refill kits" from O.D. 2) Refilled HP carts are unreliable, at best. If you are serious about refilling HP carts, get a proper refill kit and instructions from one of the online ink suppliers. I use AlotOfThings.com,
Office depot is far more responsible. The fact is that generic ink is not good.
