Why is my instax 7s flashing three red lights?

If your Instax 7s is flashing three red lights, it typically indicates a problem with the film or the camera's internal mechanisms. This could be due to a film pack that is empty or improperly loaded, or it may signify a malfunction within the camera. Try removing and reinserting the film pack, ensuring it’s properly seated, or check for any obstructions in the film compartment. If the issue persists, consult the user manual or consider contacting customer support for further assistance.
