Customer had message that said: "Cone attached to lens carriage has been turned off, airs has been turned off" The D4 LED was lit (meaning the magnet was attached correctly). The job would fail at exactly 22 seconds. Customer was using Red & Green colors. He had air turned on in the software for RED but not for Green when the Green went to run, the job failed with message at 22 seconds. Check that air is turned on for all colors.!!!!!
