He gave me a camera instax 100 he has put the batteries has pressed the red button and I mark 18 and it goes off and I press the button again and it does not turn on and when I hold the button and I put and remove the battery leaves 18 and Sige Not working What’s wrong?

@impossible , Check to see that battery contacts in camera are good and clean/free of corrosion, clean if needed. Install a set of new good quality batteries and try camera. If still not working and under warranty return for repair/replacement/refund. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
