Hi, Asmita
This doesn't work on my printer.
Firstly, your instructions are incomplete.
When I enter the IP address on my browser, this is the screen I get:
I evenutally worked out I needed to select "Network" in order to access the DNS setup screen.
Having done so and changed the settings, rebooted the router and the printer, the tried to follow the Step 2 firmware steps. None of the printer's menus corresponded to your instructions. I was able to muddle through and remove and reinstall web services.
The printer gave me a diagnostic page on its connection during this process which confirmed that it has a good connection to my wireless network.
At the end of the process it printed a page showing it had set up a new email address for the printer.
however, I still can't scan to email - same problem as before. A long wait, followed by the printer scanning and then failing with "sever error"
WHICH SERVER?
Regards
Neil
