PU K ASIC error? (Xerox Phaser 7400)

[fireflyspc]

Does anyone have any idea what this error means and how I might DIY fix it? It is on a Xerox Phaser 7400. Your help is much appreciated.

Bad black developer. ID tag is corrupt.

Thanks Michael! How do you clear the error, or fix the printer. Do you just change the black toner or imager? I have already replaced the printer with a working unit, but if I can fix this one and have it on standby that would be great.

Secondary service menu, "clear techrep faults"
Should get it reset. clear all that are there[it's one at a time} NVRAM Reset also. May need twice to sync properly.
