A tip: If your laser printer tells you that you need to change the toner, then they do not naïve. In most cases, can be a few pages (> 100) Print easily. Show indeed weaknesses in the printed image, it helps the toner from the printer to remove and well shaken this (all if applicable.) And to reinstate the connection. Thus, fixed residue stuck in the corners and there are again a couple of pages in it.
Buy recommendation? Definitely!
