Did you teach the reject mark? Sounds like a lighting issue when looking for the white sticker. You can also skip images by pressing control-repeat after the machine has found fiducials. Good luck

Hi Bobpan Thanks for the reply. I taught the reject mark but there appears to be no way to adjust the lighting for this purpose like there is in the fiducial teach screen. I have never accepted PCBs with X-outs before but agreed with my supplier t
