Não é possível conectar o scanner Dell 1600n no Ubuntu

Question

Eu tenho uma impressora multifuncional dell 1600n com scanner. A impressão não é problema, mas não consigo conectar o scanner.

Eu segui as instruções em SANE - Instalando um scanner que não é detectado automaticamente .

Quando eu executo 'sane-find-scanner' estou recebendo erro:

could not open USB device 0x413c/0x5220 at 001:004: Access denied (insufficient permissions)

A saída de ls /etc/sane.d/ é:

drwxr-xr-x   3 root root  4096 Mai  5 09:46 .
drwxr-xr-x 136 root root 12288 Mai  4 22:20 ..

E este é o resultado do comando ls -al / dev / bus / usb / 001:

drwxr-xr-x 15 root root    300 Mai  5 09:38 ..
crw-rw-r--  1 root root 189, 0 Mai  5 17:57 001
crw-rw-r--  1 root lp   189, 2 Mai  5 17:57 003

    

Answer 1

Basta adicionar-se ao grupo lp e sair / in.

gpasswd -a your_user lp

Como é uma impressora multifuncional, não é o grupo scanner .

Observe, no entanto, que este scanner não é compatível com USB !
