Ubuntu 15.10上的网络PIXMA MX925

Question

按照这个问题中的这些步骤，我设法通过scanimage -L在网络上发现了我的扫描器，但是在scanimage -T中仍然有一个错误：

防火墙也是一样的。

uname给出：

Linux 4.2.0-27-generic x86_64 GNU/Linux

再精确一点，我在Kubuntu 14.04 32位和64位上还有两台笔记本电脑。32位有效，64位无效。

更新1:用git

更新libsane

还是同样的错误。scangear当然起作用了，因为它没有使用libsane，但是我想使用Java librairie jfreesane。

更新2: git的最后一个maj正在运行

。

系统的一个标准的MAJ使这些轻骑兵像往常一样工作。

谢谢你的帮助/时间

Answer 1

考虑安装每日SANE ppa。这获得了90%的功能，我们的佳能多用途设备。唯一不起作用的是纸馈线，它适用于佳能的裸骨scangearmp2。你能为你的扫描仪找到后一个程序吗？
