How do I install an artec E-48U scanner on a ubuntu system

How do I get the scanner programs to find the artec e-48U scanner?

I don’t know what you mean by “scanner programs” but to get that scanner working under Linux (ubuntu) you need Linux drivers for that make/model.
The SANE project says it supports that make/model :

Too complcated for me.
