today my HP DesignJet T120 plotter woke up with a blue screen containing the code B3686170.It shuts down if i keep the power button and if i push the power button again it boots up in the same blue screen.
Can you help me solve this issue ? Can you suggest a way of hardware reset without using touch screen?
Thank you in advance

In dealing with Designjet support I have been told that a blue screen with error means a bad main board and requires replacement.

You need to replace HP Encrypted chip
It is inside the printer on main PCA
in USB slot
