Сетевой PIXMA MX925 на Ubuntu 15.10

Выполняя эти шаги от этого вопроса, мне удалось обнаружить мой сканер по сети с scanimage -L но я все еще получаю ошибку с scanimage -T:

То же с брандмауэром desactivated или sudo

uname дает:

Linux 4.2.0-27-generic x86_64 GNU/Linux

Еще одна точность, у меня есть два Ноутбука других на Kubuntu 14.04 32 бита и 64 бита. Работы на 32 бита и 64 бита не делают.

ОБНОВЛЕНИЕ 1: Обновите libsane с мерзавцем ppa

Тем не менее та же ошибка. scangear работает, конечно, потому что он не использует libsane, но я хочу использовать Java librairie jfreesane.

ОБНОВЛЕНИЕ 2: Последний майор мерзавца ppa работает

Типичный МАЙОР системы сделал thaht работой библиотек, как обычно.

Спасибо за Вашу справку/время
