Hello, I have a problem with my z450 printer that came all of a sudden. When I start the printer, it makes 3 “bips” and the display stays black… my computer can not see the printer anymore. I read on forums that it might be because of the RAM. Is there any tutorial or pictures showing how to change it? I would be very grateful if someone can give some hints. Many, many thanks!! Mourad
