How can I re-enable DHCP in Lexmark E120n?

[gargula]

I have deselected the option "Enable DHCP Client" of my Lexmark E120n network printer via its web configuration page. Now, the printer doesn't acquire an IP address from the router (it reports its IP as 0.0.0.0) and I don't know how to reach its web configuration page (because it doesn't have an IP!). Is there any other way to enable the DHCP option of this printer?
Thanks!

Press and hold the Cancel button (red X) on the printer until all status lights flash. This will reset the printer to factory defaults and you should be able to connect to it again.

Using the reset to factory defaults resets everything *except* the network settings, which is exactly what I need to reset... I wonder if it's possible to use that page via the USB cable?

Lexmark's support got back to me with the solution:

1. Power off the printer.
2. Open the printer cover.
3. Press and hold the Cancel and Continue buttons (the top two buttons).
4. While holding down these two buttons, power the printer back on.
5. Wait for the LEDs to blink and go to an error condition.
6. Release the buttons.
7. Close the cover.
