There was an issue a while back which caused their cloud service to be inoperable for several days, which broke many features but the printer still printed. I could be wrong but I think this is the first serious hardware problem, at least which necessitated a recall. Someone please correct me though if I got that wrong.
IIRC they had an issue a while ago where their printers were just randomly turning on and printing because of some cloud bug, that was the first one I was referring to.
