I'm getting a B504 error and I can't do anything on my printer. I'd like to clear the error.

At this point I can't do anything with my printer, it just keeps cycling through the start up process and erroring out. I'd like to remove and reinstall the ink or put it through a cleaning cycle but no luck. At this point I can't even replace the cartridges. Seems rather counterproductive.
