ET-2750 series printer / scanner

[Gordon]

Hi Folks

I have been trying for some time to install the scanner part of the above printer series.
I have downloaded and tried to install the drivers that Epson  list and have had no success at all so far. As far as I am aware the drivers have been installed, well according to gdebi, but sane xsane say that they can't locate the scanner, not detected, and I have no idea where to go from here. I have run sane-find-scanner and that came up with libusb:001:002 but it is not certain that is correct or something like that. Running xsane in root terminal i get

Unable to locate theme engine in module_path: "adwaita"

I have no idea what else there is that I can try help required please.

sudo apt install gnome-themes-standard should fix the issue

Hi VastOne

Thanks for the reply and info. Sorry that I haven't answered before now but been very busy with doing a cross stitch dragon that I have been doing for about 4 years now and have nearly finished at last. Anyway
I have installed gnome-themes-standard but xsane still can't find the scanner part of the printer. I'll try reinstalling the drivers again now that i have installed what you said and see if that makes any difference

That may be the correct output for sane-find-scanner. Try again with:

sane-find-scanner -v

You can also try to scan an image with scanimage

scanimage can also be used to locate devices. Give that a try to scan an image just to see if the scanner is up and running. I've always had trouble with Xsane.

Hi PackRat

Just run the command that you suggested and got the following

This is sane-find-scanner from sane-backends 1.0.31-debian

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

done

means nothing to me and I have no idea where to go from here
is there any other scanning software that might work ?

There's your scanner.

You can search through the Debian packages for scanner software; I've never used any.

Have you tried the Debian User Forum - I bet someone has gotten this printer-scanner to work.

Hi PackRat

The Debian forum is a waste of time. I don't remember joining them before but I must have done so but now i can't remember my password and every time i try to request a reminder / reset email they tell me the username and email address are invalid yet if i try and register with them they tell me that they are already in use so I have no way of getting on or telling them that they have a problem.
Anyway thanks for the help but still no luck I'm afraid
