This mean it is not from the toner cartridge. It could be from the black drum cartridge or from a dirty CTD sensor (located under the transfer belt).
I had the same issue when trying to replace the black toner. I put a new one in and received the error. I replaced it with another new toner and it worked fine after that. Might have been defective from the warehouse.
It's a yellow imaging unit failure.
What you can do is:
• Reseat the affected Imaging Unit.
• Check the Imaging Unit is the correct part number for this model.
• Check Transfer Belt installation.
• Cycle system power.
If the problem persists I suggest you call Xerox and ask them to fix it as this is a new unit.

Just purchased a brand new Xerox WorkCentre 6655 a few weeks ago. Unwrapped it, unboxed it, installed the drivers and the web interface for it and even registered it with Xerox. A few hours later it gives the message "Please Wait... Adjustments are in progress. System Error. Power Off then On and Notify System Administrator."
Needless to say powering it off then on did not do anything. Looking at the fault codes I see 392.670.00 but this fault code is not listed on the WorkCentre 6655 Support page fault code search.
No amount of Google fu could help me find the root of this fault code. I called Xerox support and the support that handles this printer is supposedly only 8AM-5PM Mon-Fri. The support page for the printer said 24x7 but whatever.
It's a brand new printer and giving a cryptic fault code is causing nothing but a headache. Any assistance would be much appreciated.
