Move from MX18 to 19 stops scanner working SOLVED [Solved]

[mikek]

I multiboot my optiplex 7010.
My scanner an Epsom perfection v500 photo works fine on MX18.3 and Windows10.
I added MX19.1 to the computer and installed the scanner in exactly the same way as on mx18.3, using gdebi. There were no error messages.

In mx19 simple-scan and image scan for linux and gscanpdf cannot find the scanner
scanimage -L produces this:
device `epkowa:interpreter:002:005' is a Epson Perfection V500 flatbed scanner.

I installed MX19 on my laptop and had the same problem.

Is there something different about MX19 which is stopping the scanner working?

thanks

You know what, I had the same problem. I still do, but I still have MX 18.3 on my other hard drive. So I just jump over there to scan. But if you install VueScan on MX 19, it works but this one cost. They watermark the file, until you register their software. Of course I didn't and didn't look into why on MX 19.1 it's don't scanning for me with Simple Scan or other free ones. Since your asking, I'm going to look at my again and if I fix it, I'll tell you how.

In a terminal, sudo simple-scan and it worked.
Well I should have tried that before.
But could someone please tell me how to get it working from the menu.
thanks

Have you tried clicking on it's icon?


BTW you don't need to use sudo for simple scan. It doesn't need special privileges.

I added MX19.1 to the computer and installed the scanner in exactly the same way as on mx18.3, using gdebi. There were no error messages.....

Instead of installing with gdebi, could you right click on the deb file in Thunar and choose instead the "Install Deb Files" option from the right click context menu? In MX19, I believe that gdebi can at times not work.

Then test again after installing in that manner.

If it still doesn't work, a web search brings this up where a user had his driver for said scanner work in an older version of a distro but not the new version:

and

I installed MX19 on my laptop and had the same problem.

Is there something different about MX19 which is stopping the scanner working?.....

By the way, JayM is right. The simple-scan scanner program can be called up from Whisker menu without root or sudo password. If the menu entry doesn't even open up the program, something is wrong with your installation.

Thank you all for your suggestions.
What I have done is this:

Because all scanning programs failed I assume the problem is in sane backend
I read up on configuring sane and file permissions and concluded this was far too complicated for me.
I tried installing 19.1, Same problem so I suppose the problem is caused by a change in 19.
MX is my favourite distro but I have to have the scanner working or go to another distro.
I documented what I did for future use. Here it is :-

1. Thunar - go to /etc/sudoers.d
file>open thunar as root
copy lsof.mx and rename it scanner
open in featherpad and amend to %users ALL=(root) NOPASSWD: /usr/bin/simple-scan

2. create a file in featherpad and save it. Mine is home/scripts/scanner.sh
Enter:
#!/bin/bash
# a file has been created in /etc/sudoers.d so that a password will not be requested
sudo /usr/bin/simple-scan

3. right click on desktop>create a launcher
command ‘sh simple.scan.sh’
working directory /home/mike/scripts

I works!

Thunar can be opened as root just by right clicking on the desktop and choosing the entry from the context menu.

So no need to mess with sudoers file, which is not advised.

But I still say something is wrong if you can't open simple scan without root. Was mx 19 a clean install from official iso?

Opening simple scan should be possible even if you have no working driver for your scanner. The app will simply open but just indicate that no scanner was found.

It's not clear to me what the solution to this problem actually is. Can someone please spell it out?

My scanner is a Canon CanoScan N1240U/LiDE30. I ran simple-scan from the commandline and was able to scan one page as text. But when I tried to scan the page as photo, all I got was a blank, black image; the scanner light never came on. Pressing "Start Again..." did not resolve the issue, nor did exiting simple-scan and restarting it from the commandline. It also didn't help to unplug the USB cable from the scanner and reinsert it after a 10sec delay.

I've tried xsane with similar (failing) results. Sometimes I can get one photo scan but no more. There seems to be a problem resetting the driver for the scanner so it will turn the lamp on for the next scan. Any ideas?

Also, both simple-scan and xsane take a LONG time trying to contact/locate the scanner. Is this normal?

Just to close out this issue with my (admittedly old) scanner, adding it to the USB_BLACKLIST as described in the wiki fixed the problem with the lamp. And pruning the list of backends in /etc/sane.d/dll.conf helped speed up the time taken to contact/locate the scanner.
