hpdesignjet T120
Microsoft Windows 11

I have an HP Designjet T120 and I cannot get to the point of doing a hard reset.  There is just an error code, the screen is black except for a blue square and the code B34C3844.  How can I get the print cartridges to move so I can remove them and how can I do the hard reset?

Hi @techchallened44 

 

If the printer has this type of error means that the main board is defective so there is no way to perform a Hard Reset not the carriage will move for you to remove the cartridges only if manually you can move the carriage to the left door it will allow you removing them, otherwise the printer needs to be serviced.
