Linux下一般使用sane做為掃描儀后端，安裝如下：
sudo apt-get install sane sane-utils xsane
@node1:~$ 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.

# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.
$ scanimage -L

期間也曾裝過VueScan，可以識別掃描儀，但是要收費。
$ simple-scan
終于可以使用掃描儀了。
