Mecha Error 12 on Kodak Photo 6800 printer
I had a 6850 with the Mecha error 12. No listing in the service guide for this error. I took the front of the printer off and observed that the cut head was not moving far enough to the left to trigger the sensor. I realized that a screw of unkown origin had fallen down behind the cut head and was preventing it from triggering the left sensor. It took a curved pick tool and a pair of tweezers to get it out. I don't recommend taking the cut assembly apart as the alignment is pretty crucial.
Hope this helps some poor sole from the hours of fustration that it gave me.
