I recently bought a new Multi-function printer at home - a Dell 1815dn and it works great. I am quite impressed with the speed and quality - both of which are fine for home use.
This can also scan documents and send it to a machine on the network and that was one of the features that was very useful at home, but the Windows Firewall did not like it and would block the incoming request. To allow the Network Scan to work you need to open up the UDP Port 1054 on your firewall to allow this.
Once you have opened the port, you should be able to intimate a Network Scan from the printer to the machine, however I still cannot initiate a scan from the machine itself (it comes with PaperPort and the usual TWAIN drivers/apps).
Don’t have time to dig into that now, but some day and if I find something will post it here.
