Factory Reset 8180 without cartridges

Question

Hi. I have an HP Photosmart 8180 which I had set to use a static ip address.
It used to have cartridges randomly "expire" (are they diary products?) in turn, and would not print b&w nor scan in any manner without the culprit being replaced. That's the reason why I bought new ones.
My principal printer is now a mfp lexmark colour laser w/ ADF, and I have assigned it the usual IP address.
I'm planning to keep the HP Photosmart 8180 as a backup photo and 4x6in printer.
I need to change the static IP assigned to the HP photosmart 8180, but it won't let me access to the settings/setup/whatever menu if I not replace the cartridges firts. All of them.
Now, I don't want it to conflict with the other printer, and I don't want to change the lexmark's ip address and set it up again on the clients.
Is there any way to factory reset the HP so that it will fall back to dhcp at least, without using the integrated touchscreen, or to access settings bypassing the "missing/expired" cartridge warning?
The user manual only documents doing it from the touchscreen, but I have seen HP staff PMing users with instructions to reset printers differently

Answer 1

well, solved it.
While the printer is ON, press both "print photos" and "red eye removal", then enter the sequence "red eye", "print photos", "red eye" to access the hidden menu.
I reset it from there, then it's configurable from the Embedded Web Server even if the touchscreen is trying to force a cartridge substitution.
