SCSI Epson GT 7000 Scanner Does Not Work

[billowy]

The SCSI Epson GT 7000 Scanner is detected when first logging on and running 'sane-find-scanner' but no programs seem to be able to communicate with the scanner. As soon as any program trys to use the scanner, the connection is lost.

Steps to Reproduce:
1. Login
2. Connect scanner and turn it on
3. Run 'sane-find-scanner' and it is found
4. Attempt to use the scanner with XSane or 'scanimage'

Expected Results:
The software should be able to communicate with the scanner and retrieve the scanned image.

Experienced Results:
The connection to the scanner is lost by SANE and no programs are able to use the scanner.

DistroRelease: Ubuntu 9.10

This has not yet been tested on Ubuntu 10.04

Nothing more...

Thank you for taking the time to report this bug and helping to make Ubuntu better. Are you attempting to use the XSane Image Scanner program?

[billowy (billowy)]

Thank you for your answer,
Yes I did but it doesn't recognised my scanner.
It works well with Windows XP.
What cant I do?

Thank you for responding so quickly. Please check to make sure the following packages are installed on your system:

1. sane
2. libsane
3. libsane-extras

After you have verified that these are all installed, please try your scanner again and let me know if it works.

[billowy (billowy)]

It is realy nice to have a quick help,
(sorry about my English, I do the best I can to be understood...),
I've been checking the third with Synaptic and everything is well installed.
When I start the computer, It is mooving insind the scanner (so there is something like a recognisation).
The scanner works good on windows XP.
What can I do now?

[Draycen DeCator (ddecator)]

Thank you for answering my previous questions. Please run 'sane-find-scanner' and let me know if it detects your scanner or not.

Ok,
Xsane doesn't find it anymore...
as I understand, I have to download scanimage?
Let me know.
Thank's.

[billowy (billowy)]

and now again it doesn't work...

Thank you for posting the updates. Can you please answer the following questions?

1. Was XSane working when the 'sane-find-scanner' command found your scanner?
2. Was XSane working with your scanner at any point at all?
3. Did you make any changes to your system (install updates, etc.) just before 'sane-find-scanner' couldn't find your scanner again?

'scanimage' is a command you can run to use a scanner from the Terminal, it is not a package you need to install.

Sorry this is taking so long, I just want to make we can figure out what exactly the problem is so we can get this report seen by the right people.

[billowy (billowy)]

I can't answer your questions but I find something:

When I start the computer, if I tape:
sane-find-scanner
the message is:

  # 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.

found SCSI processor "EPSON SCANNER GT-7000 1.14" at /dev/sg3
  # Your SCSI scanner was detected. It may or may not be supported by SANE. Try
  # scanimage -L and read the backend's manpage.

Then if I run Xsane, the message is:

# 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.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

Don't you think Xsane is making mess?

[Draycen DeCator (ddecator)]

It's definitely possible. After you restart your computer and 'sane-find-scanner' finds your scanner, can you please run 'scanimage -L' and post the results? Thanks in advance!

[billowy (billowy)]

billowy@billowy-Ubuntu:~$ scanimage -L
WARNING: Unhandled message: interface=org.freedesktop.DBus.Introspectable, path=/, member=Introspect

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).

[Draycen DeCator (ddecator)]

Thanks for the output. It looks as though SANE is connecting to your scanner, but is unable to maintain this connection when any other application attempts to access the sanner.

I am assigning this bug to the sane-backends package, which seems to be the cause of the problem.

The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Lucid Lynx. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.

[Draycen DeCator (ddecator)]

For more information on creating and using a Live CD, please see https://help.ubuntu.com/community/LiveCD

[billowy (billowy)]

Will you contact me after that to give me a solution?
Thank you so much for taking time for me.
I hope my scanner could work one day.
Thank you again.

[Draycen DeCator (ddecator)]

Sorry, I'm afraid I don't know what you mean. It would be great if you could test your scanner with a Live Lucid Lynx CD so we can know whether this bug has been addressed in Ubuntu 10.04 yet. I would do this myself, but I do not have your scanner to work with. You are not required to do this, but it would really help us know how to file this report. Thanks for all of the time you have committed to helping us learn more about this bug.

[billowy (billowy)]

Ok, I just know Ubuntu since 3 days so I need few help.
What you want me to do is to run a Ubuntu CD (mine is a Karmic 9.10) and run "check CD for defects"? then see the report?
Could you please explain the way to do?
Thank you.

[billowy (billowy)]

Just in case, I've just seen that a new version of Ubuntu (10.04 LTS) is downloadable. I do it and let you know about my scanner.

[Draycen DeCator (ddecator)]

Sure thing!

1. Download the Ubuntu 10.04 Alpha 2 32-bit .iso file to your home folder (http://cdimage.ubuntu.com/releases/lucid/alpha-2/lucid-desktop-i386.iso)

2. Open the Terminal and run 'md5sum lucid-desktop-i386.iso'

3. Wait for the output, which will look like random letters and numbers

4. Compare that output to the one listed for lucid-desktop-i386 (http://cdimage.ubuntu.com/releases/lucid/alpha-2/MD5SUMS)

5. If the output matches the listing on that site, then burn lucid-desktop-i386.iso to a blank CD (just insert the blank CD, right-click the lucid-desktop-i386.iso file and select "Write to disc" and make sure it burns to the CD)

6. After the download has finished, restart your computer with the CD still in the CD drive

7. When the Live CD menu comes up, select "Try Ubuntu without making changes to your system"

8. Ubuntu will load into a new default setup

9. Try your scanner (the libraries should be installed by default)

10. After you are done, simply shutdown your computer, remove the disc, then boot back into Ubuntu 9.10

11. Report whether or not the scanner worked

Thanks for being willing to help!

@billowy
We do not recommend updating your system to a developmental build unless you have a decent amount of experience with Ubuntu and are prepared for the system to be unstable. By creating a Live CD, you are able to test something such as scanner support on the developmental release without having to change your system in any way.

[billowy (billowy)]

Ok,
I abord the download and will follow your advices. It's seems to be clear and easy.
I let you when everything is done.
Thank you again about what you do for me and the community.

[billowy (billowy)]

Ok,
I canceled the download and will follow your advices. It's seems to be clear and easy.
I let you when everything is done.
Thank you again about what you do for me and the community.

[Draycen DeCator (ddecator)]

Thank you for being willing to test this bug on the latest release. Please feel free to ask me any questions if any of my steps are confusing or if you encounter any errors. We try our best to make sure that the Ubuntu experience is good for everyone, so it's my pleasure to help!

[billowy (billowy)]

Ok,
Just time to download it (It is about 4 hours for me in my small Island in French Polynesia) and burn the CD.
I go back as soon as I can.
Thank you again.

[Draycen DeCator (ddecator)]

No worries, we understand that these things can be time consuming so it is perfectly fine if it takes you a while. Besides, I'm in Chicago so I will be going to bed soon and won't be able to respond to any of your answers until tomorrow.

Je vais vous parler demain!

[billowy (billowy)]

Ok,
I did the download.
But the command:
md5sum lucid-desktop-i386.iso
doesn't work.
What do I have to do?

[Draycen DeCator (ddecator)]

What folder is the .iso file located in?

[billowy (billowy)]

/home/billowy/Téléchargements

Téléchargement = download in French

[Draycen DeCator (ddecator)]

First, enter 'cd Téléchargements' into the Terminal. This will point the terminal to look into that folder. Then run 'md5sum lucid-desktop-i386.iso'

[billowy (billowy)]

I found...
The correct orthographe was:
 md5sum ~/Téléchargements/lucid-desktop-i386.iso
I look...

[billowy (billowy)]

This is ok with the version:
4bfe7145072fa01a7e0643db5999a17a = 4bfe7145072fa01a7e0643db5999a17a *lucid-desktop-i386.iso
Now I can burn the live CD.
But I have to wait for a new blank CD because mine is out of order. It could take few days, ok?
I'll truy to catch one tomorrow whith a friend of mine to do that quickly.
I let you know as soon as possible.

[Draycen DeCator (ddecator)]

That's perfectly fine, we know these things take time. We are thankful for how willing you are to help us in figuring out the exact behavior of this problem.

[billowy (billowy)]

Ok,
I started the CD but when I choose "Try Ubuntu without making changes..." it doesn't work and I have a message:
To the top on the right of the screen: 1042009F
And a short message in a red window: E/S error Error reading boot CD - restart
What should I do?

[Draycen DeCator (ddecator)]

Thanks for the update. Here are a few things you can try...

- When you get to the Live CD Boot menu, select the "Check Disc for Defects." Hopefully this will run and check the CD for problems. If you get the same error, then try...

- Burning a CD with the slowest speed setting. Sometimes burning the disc at a high speed setting causes errors to occur in the burning process. If that doesn't work, then you can...

- Try burning with a different program (at a low speed setting again). Brasero is the default in Ubuntu, but some users have had trouble with this program. K3B is a popular option.

Of course, you always have the option of using a Flash drive with at least 1GB of space on it. In order to do that, just go to System -> Administration -> USB Startup Disk Creator. From there, simply select the .iso file for the top menu, then select your USB drive in the bottom menu. If your USB drive needs to be formatted, it would be best to close the USB Startup Disk Creator, right-click the icon on your desktop for the USB drive, then click "Format." Selecting the FAT format is usually the safest option. After you format the USB drive, then proceed with the USB Startup Disk Creator.

Hopefully this helps you. Sorry you encountered an error. Please feel free to let me know if you have any other questions.

[billowy (billowy)]

Hello,
How are you doing?
I could burn a new CD and it works. But Xsane doesn't recognise the scanner (scanner not found).
What should I do?

[Draycen DeCator (ddecator)]

Thank you for the update. I believe this report is actually a duplicate of bug 377977 after doing some research. It appears that all Epson scanners that are "supported" by a certain package are experiencing this issue, including your scanner. At this point, there is a workaround for USB scanners. Unfortunately, there does not yet seem to be a workaround for SCSI connected scanners. Thanks to your testing, I will be able to update the information on the initial report so it will hopefully get more attention from developers. Thanks again for all of your help, and please feel free to report any other problems that you encounter!

[penalvch (penalvch)]
