Scanner doesn't work after the upgrade

[huntkey]

Hi experts,

After the upgrade from 11.04 to 11.10 my scanner doesn't work any more...

It is Samsung SCX-4521F. It is multi-purpose printer. The printing part works fine so the USB connection should be good.

When I run Xsane image scanning software it says "no device available".

Help please!

Thanks!

sane-find-scanner tool can see the scanner:

found USB scanner (vendor=0x04e8 [Samsung], product=0x3419 [SCX-4x21 Series]) at libusb:007:007

But not by scanimage tool...

I have had numerous problems after the upgrade. I hope I didn't upgrade to 11.10.

Thanks,

I have tried something else but it still doesn't work... I really need my scanner... It is actually more important than the printing function of it. Help please...

Nobody knows about it? Or am I at wrong place? Is there any other place I can get help from?

I know precious little but if you can't get any help at all, someone with a passing familiarity is better than nothing.

First question:
when you do an

lsusb

in terminal. do you see your scanner?

second:
sssuming Simple scan does come with 11.x, can you use your scanner with that?

I do know porting from one version to another CAN mess with a few things. so you might want to try a reinstall if the answer to both of those is yes

sudo apt-get purge xsane
sudo apt-get install xsane

Hey Synoc thank you so much for the reply!

Yes I can see the printer.

sane-find-scanner tool can see the printer as well.

$ sane-find-scanner

I also tried to reinstall the xsane but still doesn't work. It is good try though! I should have tried it. My unity was broken after the upgrade but was fixed after reinstalling it. Simple scan can't find the scanner either... Anything else I can try?

Thanks!

I have noticed that Unity does not install all packages necessary for scanning. Check and see if "sane-utils" are installed. If not install them.

A little Googling brought me to this and it looks promising.

Best of luck.

Hey inkrypted thank you for the reply. None of them worked... I do have sane-utils installed. I can't find the scanner even as root... But thanks anyway
