From my experience Printers seem to last the warranty period, but not much more. Obviously too early to know how long this one will last. In view of their relatively low price one doesn't repair them. Just throw them away and buy another. I have two others of different make waiting to go to the tip. The lack of an instruction book resulted taking me a while figuring out how to do (manual) duplex.
At the moment it prints well. The toner is reasonably priced but one could question its life expectancy in view of its small size.
