I was away for a few weeks and forgot to pull the ink so when i went to do a print today it was not printing very well, did a few print head cleanings and than I got this error saying that the waste tank is full, being I just changed it i knew it wasn't but I looked anyways, and it wasn't. But even when I pulled my tank out the error remained which usually it tells me that i pulled it out and gives me some options. This error will not go away at all from the time I turn it on until i restart it. Anyone have any ideas on what I can do or should do, I would really be greatful.
