After working fine, the printer will not start. That is - it powers up with HP logo, and a status bar beneath in the display. And the power button is blinking. After about 15 seconds, the printer make a sound and turns off by itself and won't turn back on unless I unplug it from the outlet and plug it back in again. No messages or anything.
Thank you for the link, but is does not help me. The power and all has been checked. I does start with light and logo in the display, but after 10 secounds it makes a sound and turns off again, so I have no way to communicate with the printer.
