What default password of service menu t790 ??????

This is a service station error. One of the more common causes I have come across is a piece of paper or foreign object jammed in the service station. It is located on the right hand side of the carriage. Unplug the plotter. Plug it in and the minute that you hear the print head move, unplug the power. Then open the window, move the head out of the way and look for a foreign object stuck in the service station.

According to the manual listed below you can :
(1) Enter the OSD menu.
(2) To execute "Reset" function.
This resets all the user settings to default.

Press "Play" to change the "Administrator Password".
The factory default of "Administrator Password" is "1234".

You can configure the printer's Internet connection from the Embedded Web Server or from the front
panel.
NOTE: If an administrator password has been set, it will be required to change these settings. Thus,
the administrator can prevent the printer from being connected to the Internet, if desired.

The following settings are available:
? Enable Internet connection: The default value is Yes.

By default there is no username or password required to access CentreWare Internet Services. If a username and password have been configured for CentreWare Internet Services and you do not remember the username and / or password, reset the printer to factory defaults (NVRAM reset).
To reset the NVRAM, go to the front panel's Main Menu:

1. Select Troubleshooting, then press the OK button.
2. Select Service Tools, then press the OK button.
3. Select Reset NVRAM, press the OK button.
4. Select Reset NVRAM and Reset Printer NOW, then press the OK button to reset all the settings to their factory default values.
