I recently got used Dell MFC 1815dn (black and white laser, copy, scan, fax and print).
It has Ethernet and USB ports for connection.
After bit of search, I was able to get the printer to work over Ethernet. (found dell old drivers tar ball and extracted ppd file and manually added the printer).

I need help with scanner part.
How do I add scanning over network? sane (and xsane) don't detect it!
Do I need to tweak something to make it work?
I did find this old thread and a link to a perl file which is supposed to help. But I am unable to download the file.
