Certainly changed the behaviour - the scanner no longer hangs, but now xsane itself hangs on approximately 50% of attempts to scan - having obtained one image, it then fails to start receiving the second (though it says "Receiving gray data", or something similar, the progress bar doesn't budge). The scanner itself gets to the end of the second page then stops. Given that I'm currently able to work fine using the "non-free" Epson software, that term is starting, and that I've suddenly acquired a(nother) problem to solve before term starts in earnest, I'm afraid I'm going to have to put this down for the next week or two at least. But thank you for your efforts - if and when you or whoever the backend maintainer is have any more suggestions, please do send them to me, and I'll put them on the list to try when I get some free time.

Hi Roger, Said I'd take a look. I did.

Looks like a time out issue when the backend has told the scanner to start scanning. The backend expects the first image data back in 10 seconds but apparently the scanner it taking its time. The time out is hardwired in the sanei_epson_net_read_raw() function in backend/epson2_net.c. If you can compile from source, try increasing the value of tv.tv_sec to 60. I think that should at least get things going for you. If not, try 5 minutes (300 seconds), that's what that imagescan backend seems to be using as a worst case value.

Olaf and whoever maintains the epson2 backend, At Olaf's request, please find attached the log of a failed scan from the ADF of a ET-4500 using the epson2 backend v1.0.25 over the net, together with the simultaneously collected wireshark log, both compressed with xz.
