步骤1：首先 安装vim

sudo apt install vim

步骤2：Linux下一般使用sane做为扫描仪后端，安装如下：

sudo apt-get install sane sane-utils xsane

步骤3：搜索扫描仪

wangchao@wangchao-X3-Plus:~$  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.

found USB scanner (vendor=0x17ef [Lenovo], product=0x5625 [M7216NWA]) at libusb:001:004
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

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

步骤4：让我们第一步来检查在我们的Ubuntu客户端主机上是否存在一台可用的扫描仪。没有先前的安装，你将会看到信息提示"没有识别到扫描仪." $ scanimage -L

wangchao@wangchao-X3-Plus:~$ scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

步骤5：现在我们需要启用saned进程，用来预装Ubuntu桌面。要启用它，我们需要编辑/etc/default/saned文件，并设置RUN变量为yes：

wangchao@wangchao-X3-Plus:~$ sudo vim /etc/default/saned
wangchao@wangchao-X3-Plus:~$ sudo cat /etc/default/saned
# Defaults for the saned initscript, from sane-utils

# To enable under systemd please read README.Debian
# Set to yes to start saned under SysV
RUN=yes

# Set to the user saned should run as
RUN_AS_USER=saned

步骤6：让我们编辑/etc/sane.d/net.conf文件，并在扫描仪安装后添加服务器IP地址：

步骤7：重启saned进程：

$ sudo service saned restart 

步骤8：现在让我们来看看扫描仪是否可用：

现在我们可以打开"Simple Scan"（或者其它扫描工具）并开始扫描文件。我们可以旋转，修剪，和保存生成的图片：
