Simple Scan no longer detects the scanner after aborting a scan

[Alex Francisco Bustos Pinzon]

I have an AIO Epson Stylus Office tx300f mutifunctional printer who has scanning function.

I was scanning a text. The Simple Scan software was working correctly so, when I ordered to stop the scan, effectively the scanner stopped. But the reader-bar of the scanner didn't move to idle position.

When I tried to do a new scan, Simple Scan stopped. Then it began loading the preview for an undefined time, until it appears a message telling that no scanner is available:

WORKAROUND: Use xsane.

Hi there,

thank you for filing this bug and showing your interest in Simple Scan!

This seems to be a Hardware Issue, i.e. Simple Scan does not support your scanner perfectly -- or possibly not at all.

Unfortunately such problems happen more often then they should, and while it might indeed be a problem with Simple Scan, in our experience, most of the time it is not.
This is why we prepared a check-list at [1] that will let you find out whether or not it really is a problem with Simple Scan and what your options are in either case.

Please read that list and tell us how you decided to proceed. I will set this bug to "Incomplete", so a friendly robot will expire this bug in 60 days if you do not respond. However, we would really prefer to hear back from you!

Best Regards
Michael

[Expired for simple-scan (Ubuntu) because there has been no activity for 60 days.]

I tested this on two different old HP scanners and this happens on both. I I abort an scanning, the application can no longer detect the scanner. Depending on the model Simple Scan can hang or not.

It doesn't happen in a modern HP multifunction.

Alex Francisco Bustos Pinzon / Alberto Salvia Novella, to see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

[Alberto Salvia Novella (es20490446e)]

I'll tell you before 2016-09-18.

[penalvch (penalvch)]

Alberto Salvia Novella, if you personally would be releasing a patch towards this soon, then In Progress and assigning this to you would make sense here as per https://wiki.ubuntu.com/Bugs/Status .

@ Christopher M. Penalver

It really doesn't matter, as the idea is simply to signal that the bug isn't ready to be worked on.

[Alberto Salvia Novella (es20490446e)]

Tested with Hewlett-Packard ScanJet 4570c (ID 03f0:1305).

After the bug Simple Scan is no longer able to detect the Scanner, even by closing and reopening the application. On the other hand the bug doesn't happen in xsane, and the scanner is even detectable after Simple Scan is no longer able to detect the Scanner.

[Alberto Salvia Novella (es20490446e)]

The bug is triggered by gtk_event_controller_reset failing to reset the scanner.

[Alberto Salvia Novella (es20490446e)]

This is how it looks like.

[Alberto Salvia Novella (es20490446e)]

It also affects Ubuntu Daily.

[penalvch (penalvch)]

Alberto Salvia Novella, I'm not sure you have the same bug as the original reporter. This report is about how "Simple Scan crashes after aborting one scan and starting another".

Does your Simple Scan application crash performing the above?

[Alberto Salvia Novella (es20490446e)]

@ Christopher M. Penalver

Yes, doing exactly the same as above and with exactly the same symptoms. Just that in my scanner model the bar moves to the idle position.

My latest comments were only to explain extra symptoms I see.

[penalvch (penalvch)]

Alberto Salvia Novella, I think the title of the this report is not reflective of the original problem. From what I see, Simple Scan doesn't actually crash, but has a standard communication issue with the scanner. Hence, Simple Scan doesn't crash, or there would be a file in /var/crash. I'll adjust the title to reflect what is actually being experienced.

Hi all, If can help I experience right now tha same issue. As said by Christopher M. Penalver (penalvch) in post #15 this don't seems a crash indeed some fuctions work anyway, but, in my case, I got only the classic red upper-popup that say there's a communication problem with the source.
Then, just to try, I open Xsane and also that was link-broken to the scanner, so I try to scan usign Master PDF Editor 4 but in this case the scanning process was working.
Hope can help.
