XSane 图像扫描仪找不到 Epson WF-4630

XSane Image Scanner 和 Simple Scan 无法找到我使用了 4 年的打印机/扫描仪/复印机。打印机工作正常。它通过 wifi 连接到我的家庭网络。我正在运行 Ubuntu 16.04。

结果如下sudo sane-find-scanner：

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

could not fetch string descriptor: Pipe error
could not fetch string descriptor: Pipe error
  # No USB scanners found. If you expected something different, make sure that
  # you have loaded a kernel driver for your USB host controller and have setup
  # the USB system correctly. See man sane-usb for details.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

其结果如下sane-find-scanner：

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that

我已确保/etc/sane.d/dll.confepson2 已取消注释。如能得到任何帮助，我将不胜感激。

答案1

网络扫描需要对 epson 进行一些配置。

首先确保net/etc/sane.d/dll.config 中的注释被取消
其次 /etc/sane.d/dll.d/iscan 应该读取epkowa
第三添加net xxx.xxx.xxx.xxx到 /etc/sane.d/epkowa.conf。将 x 替换为扫描仪的 IP 地址。

我不确定这是否适用于所有系统，但就我而言，打印机需要先唤醒才能扫描。iscan 不会唤醒处于睡眠状态的打印机。

答案2

看来我的问题不是出在配置设置上。而是出在路由器上。我更新了固件，然后整个问题就出现了。我使用的是 Linksys WRT 3200 ACM。固件存在多个问题。因此 Linksys 又给我发了另一台路由器 (EAS 300)。这肯定是退步了，但至少它能用。Linksys 声称他们现在修复了固件。我还没有坐下来重新安装原来的路由器。
