After every single upgrade (2 x per year) I had to spend a couple of days troubleshooting issues to get scanners working.

Now again on 8.10 my BenQ/Acer 640BT. Most of the help on the net also make huge assumptions that everyone on the planet knows about where to get the “firmware” files for a particular scanner, knows everything about non-obvious security (being a member of groups such a “scanner” doesn’t give you the permission to use the scanner), references to directories that doesn’t exist, kernel settings for which there no way for the layman to check … and the list go on …..

Maybe I can get diploma or degree in getting scanners to work on Ubuntu …..

root@personal-laptop:~# scanimage -L
device `plustek:libusb:005:012′ is a Canon CanoScan LiDE25 flatbed scanner

root@personal-laptop:~# scanimage -T -d plustek:libusb:005:012
scanimage: scanning image of size 202×150 pixels at 24 bits/pixel
scanimage: acquiring RGB frame, 8 bits/sample
scanimage: reading one scanline, 606 bytes… FAIL Error: Operation was cancelled

what is this error ??

When I used XSANE - i have the mesagge: failed creating archive, no permission (falló al crear el archivo, permiso denegado)

Any help ??

Ubuntu are running a “brainstorm” about what needs to be improved.

People whov’e had this scanner problem might care to vote for the scanner fix.

scanimage -T -d canon630u:libusb:003:003

- that’s the wrong scanimage command. Perhaps my explanation wasn’t clear enough.

Try scanimage -T -d plustek:libusb:003:003

Canon scanners (and several others) use the generic, plustek driver, not one of their own.
So scanimage -T -d canon630u:libusb etc won’t work.

Good luck with it. I wonder if this will eventually be fixed by canonical in one of the new versions.

As a user, I don’t know, and I don’t care, who “owns” this problem but the fact that it has persisted for over a year and 2 Ubuntu versions is pretty bloody poor, IMO

“scanimage -T -d canon630u:libusb:003:003″

Soooo disappointing

Anyway: end good, all good.

The following may help if you are still be having problems with scanner operation despite using scanbuttond.

My scanner would work about 1 time in 10, apparently depending on which USB device port it was allocated when it was plugged in. I normally connect it through a USB hub. When I removed the hub and used a direct USB connection instead, operation was then 100% reliable. I tried both powered & non powered hubs & the problem was reproduced immediately in both cases.

So - worth a try if you still have the problems and are working through a hub.

People like you are the reason I switched to Ubuntu. It took some work to find someone whose tut made sense.

Your tut worked flawlessly. Thanks a bunch John and Ubuntu Geek.

A few things about this tip, esp. a correction to the original text …

Line “4. Test Basic scanner operation … ” is wrong. It should say “scanimage -T -d “yourdevice”
where “yourdevice” is something like plustek:libusb:005:008 (or whatever). I think that when originally entering the text I used the gt. & lt. signs () and the message board software tossed them out as bad html. Sorry about that. I guess most folk will have figured that out, but if you just use “scanimage -T -d” on the command line, then nothing happens or maybe you get an error message.

Auto running scanbuttond at boot time : Arthus, and others privately, asked how the scanbuttond command could be issued automatically at boot up rather than being entered manually every time at the console. The short answer is yes, you can put it in a boot-up script but, this being Linux, it isn’t as easy as just tossing the statement into our trusty autoexec.bat file. I think an explanation is too long to put here but I’ll do a separate tip on it shortly. Meanwhile, if you want to pursue this immediately, have a look at http://kudos.berlios.de/kf/kf1.html#zzboot.
