Hello jiri_kubat,
It sounds like you you are doing it right. The WPS is probably indicating that it is connected to the Wifi still.
Hello,
I'm trying to swith off the printer, in user's guide I should press switch on/off button for at least 30 seconds (???) but then the green light on switch on/off button disappears, something inside the printer starts doing some sound like printing, 2 controls (WPS and !) are enlighted blue and green, after another cca 45 seconds it comes back to the only enlighted swithch on/off button. Pls help...I may take the cable out from electricity but I´d like to do it correctly. Thank you.
