"Dependancy is not satisfiable" in trying to install two drivers for my Epson NX420 printer/scanner

I am trying to get the wireless scanner part of my Epson NX420 printer working over wifi with my ubuntu 12.10 desktop computer.

I went to the epson website here http://download.ebz.epson.net/dsc/search/01/search/searchModule to get the proper drivers. I downloaded and installed the printer drivers no problem, everything is printing great, but when I downloaded and tried to install the two scanner drivers available on the epson website in the software center I got:

Dependency is not satisfiable: iscan-data for iscan_2.29.1-5~usb0.1.ltdl3_amd64.deb

and

Dependancy is not satisfiable: iscan (>=2.21.0) for iscan-network-nt_1.1.0-2_amd64.deb

How do I satisfy these dependancies?

Also I have been trying to configure the scanner in the simple scan program to no affect, it won't recongnize any scanner.

Thats as far as I got. Would love some help on this.

Solution 1:

There are two versions of the iscan_2.29 deb-file, one with ltdl3 in the filename and one with ltdl7. For Ubuntu 12.10 you need to download the iscan_2.29.1-5~usb0.1.ltdl7_amd64.deb driver. The one you've picked (ltdl3) is for ubuntu 8.04 or earlier as explained in the FAQ at the bottom of the driver page. Also, iscan-data_1.22.0-1_all.deb needs to be installed first.
