can't scan more after "scan all from document feeder"

Please read https://help.ubuntu.com/community/SimpleScanHardwareIssues
even if this bug report is already a lot better than those initially targeted by that wiki page.

try xsane.

My scanner is:

Brother DCP-7065DN

It's networked, so no vid / pid available.

I have a good faith belief that this is a bug in Simple Scan and not in sane-backends because I actually tried with xsane and it worked there - I could scan everything in sequence, no problem.

After some "apt-get upgrade" to Ubuntu 12.04-LTS I now get this exact same problem with a Brother MFC-8660DN.

I don't know which upgrade caused the problem or when it started, but with the original Ubuntu 12.04-LTS I was able to make multiple runs.

It never had this problem before. I have to quit from simple scan and restart in order to scan more pages. The last lines of simple-scan.log are:

[+53.78s] DEBUG: scanner.vala:818: sane_get_option_descriptor (12)
[+53.78s] DEBUG: scanner.vala:480: sane_control_option (4, SANE_ACTION_SET_VALUE, "Automatic Document Feeder") -> (SANE_STATUS_GOOD, "Automatic Document Feeder")
[+53.78s] DEBUG: scanner.vala:480: sane_control_option (2, SANE_ACTION_SET_VALUE, "True Gray") -> (SANE_STATUS_GOOD, "True Gray")
[+53.78s] DEBUG: scanner.vala:422: sane_control_option (3, SANE_ACTION_SET_VALUE, 150) -> (SANE_STATUS_GOOD, 150)
[+53.78s] DEBUG: scanner.vala:462: sane_control_option (10, SANE_ACTION_SET_VALUE, 215.899994) -> (SANE_STATUS_GOOD, 215.880234)
[+53.78s] DEBUG: scanner.vala:462: sane_control_option (11, SANE_ACTION_SET_VALUE, 355.599991) -> (SANE_STATUS_GOOD, 355.567444)
[+53.78s] DEBUG: scanner.vala:1124: sane_start (page=0, pass=0) -> SANE_STATUS_NO_DOCS

As you can see the last line says SANE_STATUS_NO_DOCS so it's saying that there are no documents even though there are.

Quitting and restarting simple-scan allows you to use the scanner again, but this defeats the goal of being able to scan several times (e.g. front and back of pages) and combining them into one saved document.

Just to note: the version I'm now running is

simple-scan 3.4.1-0ubuntu1.1

This is still an issue in current raring.

Sorry for double upload, apport-collect failed at first try (but seems to have uploaded stuff anyway).

Hi Michał,

The problem appears to be that simple-scan doesn't call sane_cancel() after the last page from the ADF and this is confusing the driver. Can you try lp:~robert-ancell/simple-scan/lp-1097096 and see if this fixes it?

Hey, yes, that seems to help! :)

Fixed in simple-scan 3.6.1 and 3.7.1

This bug was fixed in the package simple-scan - 3.6.1-0ubuntu1

Hello Michał, or anyone else affected,

Accepted simple-scan into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/simple-scan/3.4.3-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

I can confirm that this fixed the issue for me. Seems like the application is faster too. Nice work.

Now running: simple-scan 3.4.3-0ubuntu1.
Still running Ubuntu 12.04 LTS.

I do not see where I can change the tag from from verification-needed to verification-done. Perhaps I do not have rights to add/change tags on launchpad.net? But I can confirm that it fixed the issue on my system.

I think I found how to change the tag from from verification-needed to verification-done and did so. If I did it in error - my apologies in advance.
