WorkCentre 7120 with strange error code?

[QrestCide]

My WorkCentre is not responsive and keeps posting error code of 117.312. I can not seem to find a reference to this code anywhere.

Can someone please explain to me what this is and how to fix it?

Hi,

117-312 Device Self Test error. Replace the printer board.

Thanks for the quick reply, Gabi!

Board as in chipset? That sounds serious. Is it repairable?

[gabiene]

ESS board. Unfortunately is not reparable.
