Hi Misty2013,
I understand your Photosmart D7460 is printing "runny" pictures and running the clean printhead didn't seem to help. I will certainly do my best to help you with this.
The first thing I would recommend checking, is making sure that you are printing on the right side of the photo paper. I know this seems like a silly thing to check, but the ink will really only stick to one side of the photo paper. Just make sure when you're loading it that it's face down, so that when it's fed into the printer it can print on the right side.
If you're loading the paper correctly though, I would ask that you try printing a photo on regular white paper. Does that come out okay, or do you get the same "runny" results?
Finally, I'd also recommend that you make sure the printer is plugged directly to a wall outlet to ensure it's getting all the power it needs to function properly.
Hope this helps, have a great day!
