CANON MF241d扫描仪无法在Ubuntu 18.04上运行


Getting CANON Mf241d scanner to work properly on Ubuntu



$ sudo sane-find-scanner

  # 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.

不知道I-Sensys MF240系列是否是ImageClass MF240系列的另一个名称,或者它们是2种不同的扫描仪,并且xsane没有任何驱动程序,还是问题出在其他地方。
