Had some fun with a vintage Polaroid pop-up camera called the 600 EXTREME — pretty normal, regular 600 format instant film camera from that period — with a portrait/closeup lens, built-in flash, and a rudimentary exposure system. Made some mistakes with exposure and focus, but it was a nice instant camera to shoot with…
If you look at your shutter button, you will notice a black piece. IF you press that only without pressing the red button, the flash will not fire. So you don't waste film try itbwith an emty film pack. On some of these cameras, both button are black.
Enjoy the camera, I love Polaroid. I own a Polaroid now and it's always fun to take photos
You probably need to clean the rollers to get rid of spread failures
