Reset printer config back to default, want to reuse ePrint email address

Hello,

I have an HP LaserJet 200 ColorMFP 276nw that I had associated to an ePrint email address.  I forgot what I set the Admin password to, so I had to reset the printer to default settings (turned printer off, pressed and held on the lower-left part of the touch screen, turned printer on until it read "Permanent storage init.").

Once that was done, I re-installed web services and added ePrint back to the printer.  Now I'm trying to use the same ePrint address that the printer had before, and I keep getting told that the address is already taken.

Is there a way to keep that address, or do I have to use a new one?

Thanks,

Michael
