In some days printer start printing by itself pages with exception report though any printer jobs aren't send to printer. Printer prints 2-10 redundant pages per hour. At this time I can print documents by Wifi or Google Cloud Print Service. Printer is connected only by Wi-Fi. Printer has latest drivers.
