reset the administrator password.

I can not reset the administrator password. Tried clearly as described in the instructions. What other options are there?

Try this 

Restore the factory-set defaults

Restoring the factory-set defaults returns all of the printer and network settings to the factory defaults. It will not reset the page count, tray size, or language. To restore the printer to the factory-default settings, follow these steps.

 caution:

Restoring the factory-set defaults returns all of the settings to the factory defaults, and it also deletes any pages that are stored in the memory.

 note:

The steps vary according to the type of control panel.

1. 2-line control panels: On the printer control panel, press the OK button.
   Figure : 2-line control panel
   
   Touchscreen control panels: From the Home screen on the printer control panel, touch the Setup button.
   Figure : Touchscreen control panel
   
2. Open the Service menu.
3. Select the Restore Defaults option, and then press or touch the OK button.
   The printer automatically restarts.

Yes, dear friend. I did exactly as you write. This is described in the instructions. The problem is this. As soon as I press the service, the printer requires an administrator password.

Hi@Alex

Try this 

NVRAM initialization

CAUTION:All HP Jetdirect settings are also reset. Be sure to print a configuration page before performing an NVRAM initialization. 

Make note of the IP address that is listed on the Jetdirect configuration page.

You need to restore the IP address after performing an NVRAM initialization.

An NVRAM initialization erases all data stored in the unprotected NVRAM sections.

Performing an NVRAM initialization resets the following settings and information:

●All menu settings are reset to factory default values.

●All localization settings, including language and country/region, are reset.

After performing an NVRAM initialization, reconfigure any computers that print to this product so that the computers can recognize the product.

1.Turn the product off.

2.Press and hold the lower right quadrant of the touchscreen. Keep the quadrant depressed as you turn the product on.

3.When the Permanent Storage Init. message appears on the display, release the buttons.

4.When the product has finished the NVRAM initialization, it returns to the Ready state.

Check this youtube video -
