The support by Canon for Linux is rather limited, and I cannot find a Linux driver for the LIDE 120 Scanner on their support pages.

And it seems that there is no support for that scanner yet in the sane package. As far as I can see, that scanner is not listed on the SANE pages. http://www.sane-project.org/cgi-bin/driver.pl?manu=canon&model=lide&bus=any&v=&p=

What is the output of

sudo sane-find-scanner -v -v

Maybe that information helps identifying whether your scanner is similar to another type where a SANE driver has already been written.

My earlier Scanner was CanoScan Lide 35 and it worked quite well with the Xsane program.

srikumar@srikumar-desktop:~$ scanimage - L

You output shows:
found USB scanner (vendor=0x04a9 [Canon], product=0x190e [CanoScan], chip=GL848+) at libusb:001:003

So the scanner seems to be based on the Genesys GL848 chip. As far as I can see from http://www.sane-project.org/man/sane-genesys.5.html the current sane genesis backend has only support for the Genesys GL646, GL841, GL843, GL847 and GL124 chips (including support for the LIDE 35).

It seems that someone has to write a driver that you can use your scanner with Ubuntu.

I suggest you contact the SANE project http://www.sane-project.org/contrib.html

Hello Every one, I am facing the same problem with Canoscan LiDE 120 with Ubuntu 14.04 LTS. Since a month passed, and I am not able to use the scanner (USB). I am queuing up my self here inorder to receive future updates regarding this problem. Thankyou. Please help me out if you find any solution.

Thank you for your response.

I do not know about programming, so cannot write a backend for this chip by myself.
Is it easy to write a program; can this be learnt easily. Can I team up with someone who does this and contribute in some way possible ?
Guess I will have to wait until someone writes the backend program.

Thanks.

The common source for scanner backend drivers is the SANE project.
I recommend reading http://www.sane-project.org/contrib.html
SANE has drivers for other Canon LIDE scanners, and I assume they would be able to create a suitable driver also for the LIDE 210, if they get the required information about that scanner and its chip.

There are also other people struggling with that problem, see among others
https://www.mail-archive.com/search?l=sane-devel%40lists.alioth.debian.org&q=lide+120

Thank you.
Have read up on the web link. many other also have the same problem with the Canon Lide 120.
Since I do not know programming - will have to wait until a backend is written for this.

re #10

What info is required about the CanoScan Lide 120 scanner and its chip ? I could try to find this info.

Since a backend is already available for the GL847 Chip, I guess it is not too difficlut to write a backend for the GL848 Chip. (?)

Please contact the SANE developers and ask them what they need.
There seems to be something going on already for the LIDE 220, see https://www.mail-archive.com/search?<email address hidden>&q=lide+220&x=0&y=0
and maybe this is the datasheet for the GL848: http://www.datasheetlib.com/datasheet/1280933/gl848_genesys-logic.html

It seems that some work is going on with the GL 848 Chip. Will wait for this to be completed.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

any luck on the Canon Lide 120 Scanner?

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Good news, now it scans and produces some distorted picture of the originals.

Hi, Pavlushka

Which Scan Program (software) do you use?
I use Simple Scan and it does not work at all

Your reply will be appreciated.
Thank you
srikumar

Hi Srikumar,
For that make your system up-to-date then you need to rebuild the
sane-backend from the latest source released & install the backend and
then use any frontends like simplescan, gscan2pdf, skanlite etc, you'll
get some result because It worked for me, BTY I use Ubuntu 14.04.3 LTS
amd64.

Regards

Pavel

Thank you, Pavel.
Will do as suggested.

I amusing Ubuntu 15.10 with all the latest updates.
How to get / rebuild from the latest sane-backend?

any suggestions.
Thank you.

Okay,
Just do this and may be this will make you smile.
Open your terminal & type
*sudo add-apt-repository ppa:rolfbensch/sane-git

#then run
sudo apt-get update
**
#then run
**sudo apt-get upgrade

#OR you can use synaptic package manager to check and make sure that
sane is up-to-date with all necessary libraries.

#It's just my suggestion to use gscan2pdf frontend to scan as for now &
bingo, it gives best result in 300 dpi till now.

*Cheers
Pavel*

Hi Srikumar,
please ignore the asterisks bedore the sudo commands before every thing you must run the "sudo add-apt-repository ppa:rolfbensch/sane-git" command.

regards
Pavel

Thank you, Pavel.

Did as instructed and also installed gscan2pdf.

The program recognises the scanner as Lide 120 and there is a lettle noise from the scanner which stops after a few seconds.
Then an error message box appears with the words "I/O error".

Do you want to see the output from the Terminal Commands?

any other suggestions?
Thank you.

The Terminal Output is as follows:-

Then you should run this command in the terminal

sudo apt-get upgrade libsane libsane-common libsane-dev

And just see.

thanks

Try the commands

sudo apt-get update
sudo apt-get dist-upgrade

The distro (short for "distribution") is the same, 14.04 and 15.10 are not different distros. They are different releases of the same distro, Ubuntu.

Don't confuse"distribution" with "release"

To Manfred,

My bad, Srikumar can try that.

I know that the wording "dist-upgrade" is misleading. It does not perform a release-upgrade, but can install/remove more packages than the plain "apt-get upgrade" command will do.

I try to explain the difference between "apt-get upgrade" and "apt-get dist-upgrade" with an example:

Say you have version 1 of package a installed, and package a version 1 depends on b1.
There is a new version 2 of package a available, but that now depends on b2, but b1 and b2 cannot be installed at the same time.

Upgrading a 1 to a 2 now requires that b1 be removed to allow b2 to be installed.

apt-get upgrade will never remove installed packages, and so the package a version 2 will stay "kept back".
apt-get dist-upgrade will do all changes.

(The command for a release-upgrade from 14.04 to a higher release is "do-release-upgrade")

Thank you for all your responses.

Have tried both suggestions one by one but the scanner does not work.
The program gscan2pdf recognizes the scanner as Canon Lide 120.
On staring to scan at 300 DPI the program stall for some time and the comes up with an error window "Error during device I/O"
The program remains frozen and requires to be force quit.

and suggestions?
Thank you.

What's the result of the previous apt-get commands??

And give us the exact results of the following commands

cat /lib/udev/rules.d/40-libsane.rules | grep 190e
cat /etc/sane.d/genesys.conf | grep 190e

Correction to my previous comment : run

sudo cat /lib/udev/rules.d/40-libsane.rules | grep 190e
sudo cat /etc/sane.d/genesys.conf | grep 190e

 and post the results & also post/describe the results of "sudo apt-get dist-upgrade" and/or "sudo apt-get upgrade libsane libsane-common libsane-dev" commands.

The OS side looks ok. Please report to the following person with your(this) question log details.

http://sane.10972.n7.nabble.com/template/NamlServlet.jtp?macro=user_nodes&user=5

you can send him a message through this link and see what happens. He is the developer of genesys backend (canon drivers) and probably the head of SANE project if I am not wrong.

Thanks, posted the logs on the SANE dev site.
Will await their response.

And one more thing, for your own privacy, hide the portion
"srikumar@srikumar" in your future posts.

Noted, Thank you.

How does hiding that add any security at all? The system will have a class C unroutable address (probably in the 192.0.0.0/8 range) which there are billions of. What can someone do with that particular information.

If an attacker found this text valuable, s/he could look at the guy's previous posts and see the text as it is now on the page...

Hiding nonsense details in hope it will add some security is nonsense. Next you'll be telling him not to disclose his CPU make and model. Same difference.

To actionparsnip
Thanks for the details, but I meant privacy, not exactly security, but your facts educating me.

Thank you all for your assistance.

Hey Srikumar,

go to the following site for sane project.

https://alioth.debian.org/projects/sane/

Register and subscribe to the sane-devel's mailing list, keep knocking them patiently, and not a recommended suggestion (Dear Andrew and Manfred, Please step in), you might do a fresh install.

Hey Srikumar,
you have to do it the harder way I guess, follow the link and we are here for farther support.

https://help.ubuntu.com/community/CompileSaneFromSource

This time we can make the thing work I hope.

Or actually you can do it in a bit more simpler way

*Open a Terminal. You need some usb libraries, and compile and build software. Some backends use avahi to discover network scanners so type:

sudo apt-get install libusb-dev build-essential libsane-dev
sudo apt-get install libavahi-client-dev libavahi-glib-dev

*Install git-core

sudo apt-get install git-core

*Download the source code

git clone git://git.debian.org/sane/sane-backends.git

*get in into the sane-backends directory

cd sane-backends

*run the command there

./configure --enable-avahi

* then run

make

* then run

sudo make install

*for any errors, post it here

Have run all the above commands.
The scanner Canon Lide 120 is detected as usual by the sacanning program - gscan2pdf.
the scanner makes a whirring noise and stops.
scanning still not working.
will restart the computer and try again.

according to this Canon Lide 120 is supported

is this a possible way:-

install WINE
run WINE
install the Canon Lide 120 driver diskette

is this possible?
any suggesstion?
Thank you.

To Srikumar,
Since 2016-03-09, you and I were in the same boat, using the latest updats of rolf-bench ppa broke my working device again (so weird, not damaged but pulled me to the state that you are in), so I git pulled (updated) the source-code of sane backends and compiled it locally using the above method I suggested you. It brought the machine to working state where even your simple scan will work. but the compiling part is important, have you been able to compile it without errors?

post the "./configure --enable-avahi" output
post the "make install" output

(To Andrew, & Manfred, if there's need to add something)

On my elementary OS (based on ubuntu 14.04) Canon LiDe 120 work great:
sudo add-apt-repository ppa:rolfbensch/sane-git
sudo apt-get update
update your system

Bought this scanner (Canon LiDE 120) today. Pavlushka's suggestion of installing the avahi libraries and compiling SANE from source worked for me. I'm using 32-bit Ubuntu 14.04. Front end is simple-scan. Thank you for this thread!

to: pixel

Thank you for your suggestion which was tried out.
Scanner is detected, making a whirring noise but does not scan.

both commands were run again since the earlier terminal logs were not available.

Tried Simple Scan
Still does not work.

went through the following link:-
http://www.sane-project.org/cgi-bin/driver.pl?manu=canon&model=lide&bus=any&v=&p=
indicates that the current tarball does not include support for Canon Lide 120
but that the development of the back-end is complete.

Do we wait for it to be included in the latest tarball ?

To Srikumar,
Your every result looks ok but its not ok because machine does not work. May be it will cause you a lot of trouble, but I suggest you to make a fresh system install and endure the pain to do it all from the start, and this time, discouraged to use the synaptic, use apt-get everytime, if you have package conflict or dependency problem, or any kind of problem, just ask here. Soon 16.04 LTS will be released, you should upgrade to that. I have tested the scanner in 16.04 beta, works fine with ppa:rolfbensch/sane-git.

Thank you, will wait for Ubuntu 16.04 and see if it is OK.

Have you tried your LiDE 120 to a different linux machine? Does it work fine in windows?

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Dear Srikumar,
Please mark this question as answered because I think your machine has other issues and this thread has some helpful instructions, so please let it not expire.

Have tried it on a different machine and it still does not work.

Have installed Ubuntu 16.04 but the Canon Lide 120 scanner still does not work.

my guess is, the scanner itself has problem, try to test it on a
windows/mac machine as canon scanners has official drivers for those
systems, otherwise your scanner might be broken, sorry to say.

It appears that Canon have the changed the chip in recent LiDE 120 and 220s from the GL124+ to the GL848+ without changing the USB product ID. I believe as a previous poster says, that the GL848 is currently unsupported by Sane. I get the impression that anyone who has made the 120 or 220 work under Sane has the GL124+ version. I'd be glad to be proved wrong, so anyone with better information please reply.

This is sane-find-scanner from sane-backends 1.0.26git

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

and My CanoScan LiDE 120 scanner is working under sane 1.0.26 build.

Many thanks for that Pavel. So 1.0.26git can work with the GL848+ chip.

I also have 1.0.26git, compiled from source.

My scanner (actually a LiDE 220 but similar to the 120 in this respect) is treated in sane-backends a GL124, though our scanners have a GL848 chip. There are source modules for the GL124 and all other Genesys chips but not the 848. For it to work for you suggests that the GL124 is compatible (enough) with the GL848.

I think my problems is that my install is not being picked up. 1.0.26 is installed to /usr/lib/, and /usr/lib/i386-linux-gnu is loaded first, containing the default Ubuntu version 1.0.22.

I need advice on elementary library paths to know the correct way to fix this. All suggestions gratefully received.

Well, re-reading the page on compiling from source and fixing the configure command makes the scanner findable. The scanner now runs, but produces completely black images. This is a different problem I think from the original poster's and I'll search elsewhere for answers. (But if anyone here knows what's wrong I'll be glad to hear!)

...and the answer to that was that I was plugged into a USB hub that wasn't giving enough power to power the light. So my posts were a red herring.

The one thing that might help people here is to point out that scanimage can be the right version, but can load an old sane backend. 'sudo scanimage -V' was returning
   scanimage (sane-backends) 1.0.26git; backend version 1.0.22
because my install from source was configured to write the library shared objects to the wrong place and not where the old ones were.

I'll suggest that if, as it appears, the GL848 is backward-compatible with the GL124, the Sane supported devices documentation lists the new chip alongside the GL124 for the LiDE 120 and 220.

My Canon Lide 120 scanner is still not working.
Perhaps the new back-end has not yet been made available for downloading.
Will have to wait until then.

Did you try
  scanimage -V
or
  sudo scanimage -V
This should return
  scanimage (sane-backends) 1.0.26git; backend version 1.0.26
If the backend version is not 1.0.26 then the installed library is not first in your path.
If so recompile - see https://help.ubuntu.com/community/CompileSaneFromSource
with the path in config pointing to where the existing
.so files are, e.g. in /usr/lib/i386-linux-gnu/sane/libsane-genesys.so.1.0.22
in my case (Ubuntu 12.04)
i.e. everything before '/sane', giving
  --libdir=/usr/lib/i386-linux-gnu
After installing, you should see new *.so.1.0.26 files in /usr/lib/i386-linux-gnu/sane/

Now run
  sudo scanimage -L
You should get
  device `genesys:libusb:NNN:NNN' is a Canon LiDE N20 flatbed scanner
N's obviously where digits can vary.

sudo is needed because there's a permissions issue. A fix is documented in
the link above.

This may not be relevant to your problem, and you may think I'm stating the obvious. But I
didn't see you typing scanimage in the forms above.

Thank you, Adrian. Trying your suggestions:-

It all seems OK but the scanner does not work.
There is a whirring noise on the scanner and the computer screen indicates a continuous process. Have to force quit the program to make it stop.
The program is Simple Scan.

Any suggestions. Thank you.

OK, well having done the things you did, I can enter
  sudo scanimage -x 100 -y 100 --format=jpeg >img.jpg
to get a small sample image.

One possibility: like me, you tried it on a USB port that does not provide enough power. But in my case, it didn't light up, there was still enough power to run the stepper motor.

If that's not the problem I'd start to suspect a mechanical fault. Obvious question. The transport lock on the underside is definitely slid to open, yes? Is the scanner element at the front end of the machine, or half-way along the glass?

I don't think you said that you'd tried it under Windows. If not, you need to find a Windows machine and install the driver and tools from the CD that came with the scanner. If it works that should rule out anything like a jammed gear at the stepper motor.

Dear Adrian

a file called "img.jpg " is saved in the documents folder.
This is just a blank file, with has nothing in it. It is opened by gedit and image viewer will not open it

running the earlier terminal commands:-

srikumar@srikumar-desktop:~$ sudo scanimage -L

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).

Further:-
on running simple scan, the following message appears automatically:-
Additional software needed.
You need to install driver software for your scanner.

on pressing "install drivers" the following window appears:-
You appear to have an HP scanner

Once installed you will need to restart Simple Scan

The transport lock sliding switch at the back is set to open
and the scanner element is at the front of the screen

any suggestions?
Thank you.

must be a loose connection., now the scanner is detected.

wow !!!
It scanned a whole page but the scanned image on the computer screen was fully black.
The scanner element is now at the top of the scanner screen and it will not move even when the unit is disconnected.
The Simple Scan program is jammed and had to Force Quit the program.

Any suggestions?
Thank you.

Oh dear, one step forward, two steps back. I thought that once the scanner was detected there would be no more problems. I don't know why you got a floating point exception or why the scanner is at the top of the scanner screen. I'd be surprised if the 1.0.26 backend which works with the 220 with the 848 chip doesn't work with the 120 with the same chip. I hope someone here will have useful ideas.

I did read that you should be ready to unplug a scanner if the element looks likely to try to go past the end, but that was just for people debugging new drivers. All I can suggest now is that you get hold of a Windows machine (laptop will do so long as the USB port can suppy 500mA), install Canon's driver (e.g. from the CD that came with the scanner), and see if it works with that. That would rule out a faulty scanner.

On another list the question of a black scan just came up. In that case,
and I've seen this myself, the scanner was plugged into a USB socket
(e.g. an unpowered hub) without enough power to turn on the LEDs but
just enough to run the stepper motor and electronics. Of course in
those cases there wasn't a floating point exception. Plugging directly
into a PC worked. Worth a try.

The scanner works somewhat.
But the output is a black page.

Are you absolutely sure that the USB port is giving enough power? Are you using the original USB cable? Can you try it with another cable?

Other reports of black scans (including my experience) were due to lack of USB port power. If it's not that I don't know what it could be - I wouldn't rule out a device fault. Can you try it on a Windows PC using the supplied installation CD?

Thank you for the response.

I have removed the original long cable (3 feet) and am using a short (1 foot) cable.

It works well in Windows XP. Since a double boot is being used, every time a scan is required I boot into Win XP to do it.
The Sane Developers site indicates that a backend is still in development. Will have to wait.

Thank you.

The SANE project indicates that the development for the Canon Lide 120 scanner is "complete"
How to install the latest backend for this scanner.

At present the scanner is detected and it scans BUT the out is a black page.

any suggestions. Thank you.

If you can use the same USB port successfully under Windows XP then it ought to be giving enough power. The only cases of black images I've heard of have been due to underpowered USB ports, when the stepper motor works but the LED array doesn't light up. Does the LED array light up under XP but not under Linux? If it also lights under Linux, sorry, I don't know what it could be.

If it doesn't light using Linux, if you have access to a powered USB hub (one you also plug a charger-type adaptor into) you could try that just in case it's a power issue that somehow only happens under Linux. I don't know if that scenario can happen, but maybe worth a try.

Thank you Adrian.

The Scanner works physically OK. The LED scanner light comes on and the scanning unit moves along the page. The result however is a black page.

Perhaps the SANE software need to be updated.

$ sudo scanimage -V

Wow!!!
after upgrading to Ubuntu 17.10 this morning, the Canon Lide 120 Scanner is working with the Simple Scan software.

Thank you.
