ubuntu 14.04 stampante epson wf-2650 scanner non funzionante

si collegandola con usb funziona tutto correttamente, mentre se la faccio lavorare in wi-fi allora mi da errore.

Ho installato il package della stampante epson-inkjet-printer-escpr_1.6.32-1lsb3.2_amd64.deb ed anche l' iscan.

Da usb lo scanner funziona correttamente.

l'output dei comandi è questo:
