Difficulty getting scanner to work with Debian

Postby Yuhan » 2017-06-25 20:58

Hello! I have a new Gigabyte computer with Debian 8 installed. I am having a rough time getting my Canon Lide 110 scanner to work with Debian. Ideally, I'd like to use simple-scan because it's easy and most of what I scan are simple text documents. According to the "preferences" on simple-scan my scanner is recognized and there are no problems. When I hit "scan" the scanner seems to run for a ridiculously long time and then a sign comes up that says: "Failed to scan. Unable to start scan." Very frustrating. I realize scanning in Linux can be a bit tricky but I need to be able to scan and forward text files quite often. Any help will be greatly appreciated! Thanks in advance.

I should add that my scanner does work using xsane. The problem is xsane is really more than I need and simple-scan is actually better for multiple page documents. With xsane I can only scan pages individually. What's weird about this is that both xsane and simple-scan have (as I understand it) the same "sane" back-end settings, so if one works the other should as well. Thanks.

Try simple-scan as root in a terminal and see what the output is.

A few suggestions here to try: shorter cable, no hub, USB2 instead of USB3.

Thanks for this. Can you tell me exactly what I need to put in the terminal to run simple-scan? Actually I do use a hub (Anker) and it is usb3! Why would usb2 work more effectively?? That seems strange.

Get root by entering

Code: Select all
$ su -
and then your password and then enter

Code: Select all
# simple-scan


It is possible simple-scan has an issue communicating over USB3: to find out, plug the scanner directly into a USB2 port if you have one.

Tried getting scanner to work from root...still no go. Not sure what else to try. My computer is new and probably has usb3 ports, not sure. Is there a way to get updated drivers for simple-scan?

Also tried plugging scanner directly into computer...no difference at all. Is this likely a sane issue or a Debian issue? There is probably a simple solution to this...very often that's the case with these issues!

Interesting...

I have canon lide 110 scanner too, and it just works with debian. Worked in Jessie and now it works in Stretch. I never installed any drivers for it.
And I use simple scan.

One thing that comes to mind is that are you sure, that the scanner is not locked for transportation? From the switch that is under the scanner.

And are you sure your scanner gets enough electricity? You could try an usb-hub with its own power.

Really strange, that your scanner works (or was it worked? ) with a different program. Obviously if it does work, then my suggestions are not possible..

Yes, xsane works just fine on my scanner. And it is attached to a usb hub with it's own power. This makes it even more strange that someone else has had positive results with the same operating system and scanner. Anything anyone can suggest will be welcomed!

What are the steps that you take when scanning with simple-scan? Maybe there's something I'm overlooking in the setup. But I can't imagine what that would be. Thanks again.

Okay! Some results...finally! When I hit the icon "start a new document," the page scanned just fine! I printed it out and it looked okay. When I hit "scan," however, the scanner is not recognized. Can anyone explain this? If all you have to do is hit "start a new document," why is there a "scan" button at all? I think I figured out how to make this work....but I'm not exactly sure why it works.

I spoke to soon! I tried again today to scan with "open new document" and absolutely nothing happened! I guess what happened last night was a fluke. Basically the scanner is not responding at all, unless I hit "scan" and that does nothing but cause the scanner to make noises! I've been reading that sane can actually be dangerous for scanners. Is this true? It can send bad signals which will lead a scanner to break down. Sometimes when I attempt to run simple-scan or xsane the scanner will make long protracted sounds like it's being overworked. Scanning appears to be a weak link in Linux. Not sure what to do as I have a lot of scanning I have to do for business purposes.

To follow up on FreewheelinFrank's suggestion re. usb2, have a look at Gigabyte manual as will probably show which usb sockets are usb2 and which are usb3. Likely has a mixture of both. Can't use usb sockets intended for mouse / keyboard though. I put a small cheap expansion card hosting 4 usb2 sockets in a Gigabyte board although there should be board headers for usb to save using an expansion slot. This was a result of my destroying the mobo's own usbs, probably from using unsafe powered usb hubs. If there are no onboard usb2 sockets, before considering furthering usb2 sockets, check what other slots and headers are on the mobo. Incidentally i have noticed similar problems in the past on another distro (not Debian) that 'scan' button didn't work but 'start a new document' did.

I'd be interested to know where you read that Sane is dangerous for scanners.

Scanners make noises- don't let that put you off.

aplistir has said that your scanner works in Debian; Sane says support is complete.

http://www.sane-project.org/sane-backends.html

Xsane maybe a bit ugly, but it does work.

simple-scan doesn't work for you, but that may be an issue with your install or your hardware.

Looking through your previous posts, it seems you installed from a live USB; I wonder if USB may have been wrongly configured somehow. Just guessing here. I hope somebody else can help you.

Another thought, following on from my recognizing similar bugginess with past usage of simple-scan on another distro. Problem could be to do with 3.14 version of Gnome in Debian 8, if you're running Gnome IDE. May find upgrading to Debian 9, which offers Gnome 3.22 solves it.

Before upgrading to Debian 9 here is another possibility. There is a more recent version of simple-scan than the one installed on my computer. The newer version is 3.25.1. I downloaded the tar.xz package and opened it on my desktop. I now have a folder for 3.25.1 on my desktop. What do I need to do to integrate that folder into my system? Is it handled through a terminal or is there something I can do directly with the folder itself? I want to try this to see if perhaps it will resolve the problem. Given the comments about the general "bugginess" of simple-scan I kind of doubt it. Still, it's worth a try.
