SimpleScan detects my Canon Lide20 scanner. enter image description here

When I start scaning, it seems working but makes a "fake" scanning, black rectangle grows simulating a scanner process, but scanner does not start phisically, no lights, scanner head not moving, etc. enter image description here and thenenter image description here

this is the output of lsusb:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 8087:0a2a Intel Corp. 
Bus 001 Device 002: ID 04f2:b56b Chicony Electronics Co., Ltd 
Bus 001 Device 005: ID 04a9:220d Canon, Inc. CanoScan N670U/N676U/LiDE 20
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Any ideas? Thx!


Simple scan is a very basic app for scanning. You can install xsane and do a scan either from xsane or using gimp since those two are fully compatible (xsane installs the appropriate gimp extension automatically) and xsane delivers extremely better results and has many more options.

apt-get install xsane

  • Given that Simple Scan uses exactly the same SANE backend as Xsane, it's unlikely that this would solve OP's problem which sounds like a driver issue. – Andrea Lazzarotto Jun 1 '17 at 20:20
  • Yes, there's a chance xsane may not work either. Simple scan did have problems with my HP scanner though and it turned out that xsane was working fine every time. If xsane fails too, you'll probably be right. :) – Stormlord Jun 1 '17 at 20:44
  • SimpleScan works well even with Ubuntu Gnome live USB, but does not work after a fresh installation. – Silken Jun 1 '17 at 20:45
  • SimpleScan also works in Antergos Arch linux, but does not works under Manjaro, the symtoms are the same. I'm not sure that its driver problem. – Silken Jun 1 '17 at 20:47
  • Under earlier Ubuntu versions (and also under Arch) SimpleScan worked correctly, I'm using it since many years. – Silken Jun 1 '17 at 20:49
