O dispositivo em questão é uma Epson WF-3640. Eu consegui fazer com que este dispositivo funcione como um scanner / impressora de rede com todas as versões do Ubuntu desde o 14.04, mas o caminho anterior de instalar o pacote do iScan e mudar os arquivos dll.conf / epkowa no /etc/sane.d não parece funcionar.
Instalação do iScan bundle 1.04:

No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages).
Alguma idéia de como eu posso fazer isso para que o scanner funcione novamente? atm Eu inicio em um sistema 16.04 para escanear, mas prefiro poder mudar para 17.10 completamente.
