Photosmart all in one c7280 error codes

I have a Photosmart c7280 all-in-one and have gotten a couple error codes that came up on its display screen: B04952c6 and B043cfc5. I've tried searching but can't find anything on those particular codes. I just find a page that tells how to reset the printer. How can I find out what these codes mean. I'm using windows 7
Thanks
