Thank you everyone for the suggestions.
I just also wanted to add to the thread that the FX 9600 recently had a firmware update come out from zebra. I went to update my firmware and it turns out it was the original firmware from when I bought it. So I updated the firmware and then managed to program a hundred tags last night. Without too much issue. Some tags didn't want to program so I had to go back and double check my work constantly. On second attempt on the tags that didn't program the first time around they seemed to program. No problem. Maybe I'm getting interference from other tags too close
I'm doing this in an office so maybe I should stick the tags in some kind of covered container?
