HP DesignJet T520 36-in Printer
Microsoft Windows 10 (64-bit)

The printer has the error code B36929C8 with a blue screen. Tried to power off and on and the error code still appears right away.

Can be either a bad firmware storage device on the main board or the mainboard itself. In my experience, it will be the firmware device 95% of the time. Part number is CQ890-67105 and you can purchase from the HP Parts Store.  You will need to remove the left side cover in order to replace it.
