I dont know why this is a big secret or so hard to find.
Use at your own risk, but it was easy to reset.
Reset Admin Password:
Hold the Home (house) button down on the printer for 6-8 seconds, then let go.
Then enter the default passcode: '6789'
A menu with full access will come up.
Go down to "Resets"
Tap on "Reset to Factory Defaults"
Custom settings and passwords will be reset.
Thanks. This is a quick and easy way to reset the printer to factory settings and clear a forgotten Admin password.
I can use that 6789 password to get into the "Service" login, but when I try to Resets, I get a "Unable to continue. Try again later"
That was all the info I could find on the password.
I forget the prompts in the menue it's been a few months since I reset mine, do make sure you read all the prompts my guess is the wording might be differant in the menue so go through it carefully.
or it did not like the pasword you made for some reason think I recall it having to be so long and being picky on what was entered.
