Scan fail at ~50% when scanning at 1200dpi over Wifi

[Saivann Carignan]

When scanning at 1200 dpi with HP Photosmart C6180 over wireless network, the scan goes well until approximately 50% of the scan has been done, after what a little window appears saying that simple-scan can't communicate with scanner and all computers in the local network can't communicate with the scanner anymore, and even the http address of the scanner is unavailable until it is rebooted. Clicking on "Scan" button again crashes simple-scan if you try it twice. This is always reproducible.

Similar tests that work flawlessly, tested at least twice :
- xsane at 1200dpi, wireless
- simple-scan at 1200dpi, usb
- simple-scan at 600dpi, wireless

Steps to reproduce :
(Have a wireless multifunction printer/scanner)
1. Set photo profile to 1200dpi in Document / Preferences
2. Click on scan and wait.

Result : Scan fails

3. Click ok and click on scan again.
4. It fails, click ok and click on scan again.

Result : simple-scan crash

Terminal output, debug log and backtrace attached.

I have the same problem with my USB HP 4400c on Ubuntu 11.10. Happens while scanning with 1200dpi in both xsane and simple-scan.

jerko, yours is different (xsane fails). please open a new report if you wish so.
saivann, is this still happening?

This specific bug is not reproducible anymore..!

However Simple-scan 3.2.1-0ubuntu1~oneiric1 now produces a stretched impossible-to-read picture when scanning at 1200dpi with this scanner.. But xsane also have the same behavior, so that does not seem to be something that needs a fix in simple-scan.

I scanned 5+ pages at 600dpi, which also used to fail after some minutes and everything went well.

Thanks!

great! i am closing this bug report then.
the other issue sounds like an issue with the sane backend and should be verified to work with scanimage/xsane before looking into it further.
