Ubuntu 16.04: erro de E / S de varredura simples

Question

Ao tentar digitalizar com o recurso de digitalização simples, muitas vezes (mas nem sempre!) recebo um erro de E / S informando que o scanner está inacessível. Não acho que seja um problema de conexão física (problema com cabo ou porta USB), porque a impressão com o mesmo dispositivo funciona sem problemas.

Estou usando o Ubuntu 16.4. e meu aparelho é o Samsung SCX-3205W. Eu instalei os drivers mais recentes do site do produtor.

Aqui está a saída do console da verificação simples:

Answer 1

No momento da gravação, esses 3 pacotes precisam ser baixados e instalados.

libsane-common_1.0.26~git20151121-1_all.deb
libsane_1.0.26~git20151121-1_amd64.deb
libjpeg62-turbo_1.5.1-1_amd64.deb

Os dois primeiros pacotes podem ser encontrados nas bibliotecas experimentais do Debian neste link link

O último pacote que encontrei neste link link

Em alguns casos, você pode precisar navegar para um site de espelho ftp para fazer o download. Uma vez baixado, basta instalar cada pacote como root, por exemplo. sudo dpkg -i package

Eu testei com scan simples, xsane e scangearmp e tudo funciona bem.

    

Answer 2

install libsane-common_1.0.26~git20151121-1_all
install libsane_1.0.26~git20151121-1_amd64
install libjpeg62-turbo_1.5.1-1_amd64

Loaded repository 
http://ftp.ports.debian.org/debian-ports/
synaptic only comes up with 1.0.27-1 experimental2
for sane-common. No libsane option.
Unable to find the link

The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.

Teve que remover repositórios e reinstalar a libsane libsane-common sane e simple-scan
