Default password for HP Laserjet 1536dnf

[hck4]

I am trying to access my service menu on my laserjet 1536dnf printer. It asks for a for a password which I can't even remember to have set. Could you please help me to get a new password?  I saw you send a way to reset the printer - will be happy to have similar solution.
(I have tried 2 suggested default passwords from the forums here, with no success)

Thanks!

If you need to restore all the settings, print out Configuration Report from front panel.

Then do as follows.

Product resets
To restore the product to the factory-default settings, follow these steps.
1. Turn the product off.
2. Press and hold the Right arrow button and the Cancel button at the same time.
3. While holding down both buttons, turn the product on.
4. Continue to hold both buttons until Permanent Storage init. appears on the display, and then
release both buttons.
