Epson ET-2760 scanner not detected, Ubuntu 18.04

[Minilek]

Hi all.

I just bought an ET-2760 scanner and tried to connect to it via wifi from my laptop (running Ubuntu 18.04) to scan a document. I followed these steps:

1. I went to http://download.ebz.epson.net/dsc/se...h/searchModule and searched for ET-2760 as the product, and Linux as the OS.
2. I downloaded the "All in one" package at the bottom of the resulting page.
3. $ tar xzvf imagescan-bundle-ubuntu-18.04-3.65.0.x64.deb.tar.gz
4. $ cd imagescan-bundle-ubuntu-18.04-3.65.0.x64.deb, then $ sudo ./install.sh
5. I also looked in core/ and plugins/ and dpkg --install'd every deb file in those two folders. There were 4 total, and these were the filenames:
imagescan_3.65.0-1epson4ubuntu18.04_amd64.deb
imagescan-plugin-gt-s650_1.0.3-1epson4ubuntu18.04_amd64.deb
imagescan-plugin-networkscan_1.1.4-1epson4ubuntu18.04_amd64.deb
imagescan-plugin-ocr-engine_1.0.3-1epson4ubuntu18.04_amd64.deb

Now, scanimage -L says "No scanners were identified." Similarly, imagescan says "No devices found". Note: I lost the ->usb cable that came with the printer, and I'm trying to connect with it for the scan over the network. The printer and my laptop are both on the same WiFi network. I can successfully print over the network, but I'm just running into problems detecting the printer for scanning. Any thoughts on what I should be trying here?

Is your ET-2760 connected to your router? If it does not have an IP address there is no way your computer will see it. The Epson ET-2760 User Guide gives some good instructions about connecting your printer to the router. Beginning on page 30 of the User Guide is a whole section on wifi setup for your printer. User Guide can be viewed at https://files.support.epson.com/docid/cpd5/cpd57083.pdf

To him610: yes, the printer is connected to the router (accomplished via the printer's setup menu on the device itself). Note: I can print over the network. I just can't scan over the network.

On Ubuntu 21.04 a user would be given sane-airscan by default. You will have to download and install it from

https://download.opensuse.org/reposi...u_18.04/amd64/

The main page is

https://github.com/alexpevzner/sane-airscan

Please give

scanimage -L

airscan-discover

[Minilek]

Thanks, that seemed to do something!

minilek@minilek-laptop:~$ scanimage -L
device `airscan:e0:EPSON ET-2760 Series' is a eSCL EPSON ET-2760 Series ip=192.168.86.207

How do I actually scan documents though? imagescan still doesn't see the scanner.

[brian_p]

Can you scan with

simple-scan "airscan:e0:EPSON ET-2760 Series"

[Minilek]

That worked, thanks a lot!
