Hi Manavoc,

I will explain you the cause for it.

It prints in yellow first and then override with black for better quality. This is the reason your color ink gets empty.

If is an original brand? Some generic cartridges or refill ones gave that problem.

I think I know what is the problem. I refilled my black ink cartridge and it printed for a while, but at some point it just stopped working. The head wouldn't touch the paper. Initially I thought the printer had a problem, but then I discovered that the color cartridge still worked.I had a spare new cartridge so I changed it. Everything worked just fine afterwards. My hypothesis is that HP tracks an identifier in the cartridge and does NOT allow you to refill (I even think they simulate for the cartridge to be failing, but I still have to corroborate this). I think this is outrageous and illegal. Please let other people with the same problem know about it. So, the solution is to stop using HP products.

Try cleaning the print heads. You can find more troubleshooting info in the manual:
