I have not worked with Epson printers in years, so it maybe something else: I have been trying to get a friend's Epson NX400 printer scanner functioning. I installed the device and it worked well. Then my friend moved the printer/scanner and added an extension cable to make the connection to the new location. Now the scanner is not recognized by Xsane, sane or GIMP. Each is still reflecting the model number of my friend's previous printer.

The printer prints flawlessly, the copier copies, but the system does not recognize the scanner at all.

Any ideas?

Thia will sound strange. But 1.8m.
This is as much as you go. Not less not more. Do not know why.

really strange thing is happening, try moving it back and seeing if it works, then have a good laugh when you see that it does :P.

when working with data controls for gate systems we had simular faults. Used optcally coupled line (like fiber cable with converter) our IT dept did it the fiber optic line was over 300ft

Move it back to the original setup and see if that fixes it.

I guess after more than 5 years the OP has solved the problem or just moved on.
