Not a question but a note: Apparently it can happen that the printer can no longer be switched on (e.g. in my case). If this happens after the warranty period has expired and you want to continue using the device, there is a work-around: 1) Disconnect the device from the power supply and wait approx. 10 seconds; 2) Simultaneously press the on/off switch on the device and reconnect it to the power supply. 3) The printer should then start up again. Unfortunately, you always have to do this from now on. I therefore use a power strip with a switch so that I don't have to fumble around with plugs.
