Product: DesignJet T120
Operating System: Microsoft Windows 7 (64-bit)

Hello everyone,

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.

Many times an HP printer fault has self rectified by turning machine off,  pulling plug from wall socket and waiting 10 minutes before re-connecting and re-booting.

You need to replace HP Encrypted chip 

It is inside the printer on main PCA 

in USB slot 

Like this one
