T520 blue screen B3393226 code

[BeemerBiker]

The blue screen error code B3393226 on an HP DesignJet T520 plotter means a firmware assert or crash, usually caused by a corrupted internal firmware USB/flash storage device plugged into the main board.[ref_1, ref_2]

What Causes This Error?

• Corrupted Firmware Flash Drive: The internal encrypted USB module that holds the printer's operating system has failed or corrupted data.

• Main PCA Board Issue: Less commonly, the main system board itself has stopped working properly.[ref_1, ref_2]

How to Fix It

• Power Cycle / Hard Reset: Unplug the power cord for at least 5 minutes, then plug it back in. If it's a temporary glitch, this might clear it, though "B" series codes usually persist.[ref_2]

• Replace the Internal USB Firmware Module: The official HP replacement part is the HP USB New Module with F/W SV (part number CQ890-67105), which acts as an encrypted firmware storage key. You access the main board by removing the printer's left-side cover.[ref_1, ref_3]

• Advanced Community Fixes: Some users opt for community-driven workarounds like cloning a working flash drive onto a new USB stick, though results can vary.[ref_1]
