This seems to be a commercial product. For the best chance at finding a solution I would suggest posting in the forum for HP Business Support!

I'm getting the same error code on my HP laserJet 500 color M551. It prompts me to turn off and turn back on, but it continues to say this after each rebot. Any suggestions on how to fix this? Thanks!
