扫描易试过么

可以右键终端 执行 scanimage -L 命令 看一下能否发现扫描仪。如果有内容 可以尝试使用商店里面的 亮仔扫描 看看

不懂帮顶

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).

这是扫描结果，没有扫描到。

没试，有时间试试，谢谢。
