Let revisit this. Customer tried to do punch through this. Thought that I had it licked, I guess she did not punch this whole time. So on the phone with KM and did some stuff without any success. I replace the exit sensor of the copier and exit rollers, reflashed the finisher firmware to 70, replaced the finisher control board, the finisher entrance sensor, entrance rollers. Now KM wants me to return to standard data. I was Just wondering if this was the way to go? Just out of ways to go I guess.
