Unreliable network connection between lap top running ubuntu 13.04 and Epson Workforce WF-3520 printer scanner

1. As you can see from https://wiki.ubuntu.com/Releases Ubuntu 13.04 is no longer supported. I recommend you upgrade to 14.04 (support until April 2019)

2. For the drivers please open the page http://download.ebz.epson.net/dsc/search/01/search/?OSC=LX&productName=WF-3520 and click on the magnifying glass icon in the middle of the screen

Thank you for your help! Ooops, sorry....I'm on 14.04...typo! I managed to find the drivers on the epson web site before posting this but I got totally confused by a plethora of different downloads so gave up, your link took me to where I've already been. I also tried uninstalling the printer and re installing to no avail, I think Ubuntu installs generic (is it SANE?) drivers and I'm not sure if that's the problem or not?

as far as I know you need to install several packages for the scanner:

1. From the core package & data package page the iscan-data_1.29.0-2_all.deb package
2. From the core package & data package page the iscan_2.29.3-1~usb0.1.ltdl7_amd64.deb or iscan_2.29.3-1~usb0.1.ltdl7_i386.deb package (depending on your architecture 32bit or 64 bit)
3. From the network plugin page the iscan-network-nt_1.1.1-1_amd64.deb or iscan-network-nt_1.1.1-1_i386.deb package (again: select the one fitting to your architecture)

The terminal command sane-find-scanner should be able to identify the scanner. What is its output?

Hi, thank you for your help. I think my computer is 64 bit so does that mean I use driver _amd64deb?

I tried those installs but am not sure which ones I chose and I ended up with an error message which hung around for a week or so then disappeared!

I've pasted output below if it makes sense?

What is the output of :

lsb_release -a; uname -a

Is web access ok on the system?
Can you ping the IP of the device?

Thanks

Hi and thanks for your help.
Output below.
web access fine but it does drop sometimes, sorry I don't know how to ping the device...I'm new to Linux and rubbish with IT!

Something that may be relevant is that I (unfortunately have to) also use Windows 8 on this computer and have no issues, I installed their drivers from the supplied CD's, ignored their suggestion to use their web site for latest version at the suggestion of our ink supplier as they say they will force us to use their expensive ink!

What Windows does or doesn't do is of little reflection on Ubuntu. It is a completely different OS with completely different support.

If you use your Windows OS you can get the IP. The ping command is the same in Ubuntu as it is in Windows.

I just thought it might be relevant because this seems to be an issue I only have with ubuntu, don't know much about such things!
I think I need instructions on how to "ping the IP of the device" as I don't understand what this means or how to do it. Sorry for being so useless! Thanks again for your help so far...

1. Your system is 64 bit, so you need to install the _amd64.deb and _all.deb packages.

What is the output of the terminal command
dpkg -l | grep iscan

2. According to your original question "failed to open device epson2:net:192.168.1.64 error during device I/O..." the IP address of the device should be 192.168.1.64

So what is the output of the terminal command
ping -c 3 192.168.1.64

Hi Manfred, thanks ever so much for taking the trouble.
Your first question:
phil@phil-Compaq-CQ58-Notebook-PC:~$ dpkg -l | grep iscan
rc iscan 2.29.3-1~usb0.1.ltdl7 i386 simple, easy to use scanner utility for EPSON scanners
ii iscan-data 1.29.0-2 all Image Scan! for Linux data files
phil@phil-Compaq-CQ58-Notebook-PC:~$

Is your second statement saying I should change it to that - I take it you mean minus the word "net"? Not sure how to do it if that's what you do mean - sorry!

Third question:

phil@phil-Compaq-CQ58-Notebook-PC:~$ ping -c 3 192.168.1.64

phil@phil-Compaq-CQ58-Notebook-PC:~$

For reasons unknown I'm having no scanner or printing issues today!

If I install the drivers you suggest does that mean I have to un install the existing before I do?

Many thanks again for all your help!

1. The question with respect to IP address:
You wrote that you do not know how to ping the device, and so I tried extracting from your previous output the relevant information.
The ping command that you executed shows reasonable response from the device that I assume is the scanner. No further action is required with that.

2. The dpkg output shows that you only have the iscan-data package installed, but not the two other packages.
I recommend that you download the two other packages and install them. No un-installation is required before.

Hi Manfred,

Still need to download the drivers, going to do it tomorrow but in the
meantime I tried the ping test whilst I was in the midst of a non
responsive printer again and got a different terminal message as follows:

phil@phil-Compaq-CQ58-Notebook-PC:~$ ping -c 3 192.168.1.64

Either the printer/scanner was not switched on or not connected, or you have a general problem in your network.

Hi Manfred, I'm back again! I installed all drivers as instructed and have been seeing how things go but still have the same problems. Today I have internet connection but can't print or scan. I tried looking online for general network problem fixes and managed to get the following output but I don't understand it! Here it is:

2. How is the scanner connected?
I understood that you have a network connection, so you have to find out the IP address (or hostname) of your scanner.
I assumed that it is 192.168.1.64, but that seems to be wrong.
Maybe putting the IP address into /etc/sane.d/epkowa.conf helps (look into that file for instructions).

Hi Manfred,

I tried the first download from epson web site but it said:

"conflicts with the installed package 'iscan'...."

The second download appeared to download successfully.

I'm really sorry but I don't understand what the following means:

Maybe putting the IP address into /etc/sane.d/epkowa.conf helps (look
into that file for instructions).

1. You should download both packages from the Epson web page and install them with one single command
sudo dpkg --install iscan-data_1.31.0-1_all.deb iscan_2.30.0-1~usb0.1.ltdl7_amd64.deb

2. What is the IP address of your scanner?

3. It might be necessary to edit the file /etc/sane.d/epkowa.conf helps and to put the IP address of that scanner into that file. Read the contents of /etc/sane.d/epkowa.conf !
Issue the command
sudo gedit /etc/sane.d/epkowa.conf
and put the line
"net the-ip-address-of-the-scanner"
into it, (without quotes and with the real address of your scanner, something like net 192.168.2.15).
