e=3511, says "Install Color Toner Cartridge"

[Oystercopy]

I believe I've seen this problem before, but usually I clean the sensor in the back of the revolver unit and its fine. I believe I blew enough canned air in behind the revolver to clean that sensor, but it's now stopped the machine cold...
Anyone ever have any of those sensors go bad? I'm having a HECK of a time figuring out which sensor it is in the parts list.
Thanks in advance,
OC

ok.. its been a while... the sensor u need to replace is the one that is removed from above the revolver unit ..remove the plastic cover that the copies rest on (or if u have finisher remove finisher, bridge unit,then cover) remove the screw holding the sensor bracket on and remove the sensor from machine. clean it.... test ir with 03 mode....
