If your Instax Mini 9 is blinking orange (on the flash indicator light) even with a new battery, it typically indicates an issue with the flash charging or the batteries themselves. Here are some possible causes and solutions: 1. Weak or Incompatible Batteries: Cause: The most common reason for the orange light blinking is that the batteries do not have enough power to charge the flash. Solution: Use fresh, high-quality alkaline AA batteries (not rechargeable or low-quality ones). Make sure they are brand new and not partially used. 2. Battery Contacts Issues: Cause: Dirty or corroded contacts can prevent the batteries from properly powering the camera. Solution: Check the battery compartment and clean the contacts with a dry cloth or cotton swab if necessary. 3. Battery Orientation: Cause: If the batteries are inserted with the wrong polarity (+ and -), the camera won't work properly. Solution: Double-check the battery orientation and ensure they are inserted correctly according to the symbols in the battery compartment. 4. Stuck Flash Charging Circuit: Cause: The camera's flash charging circuit might be stuck or malfunctioning, causing the orange light to blink. Solution: Turn the camera off, remove the batteries, wait for a few minutes, and then reinsert the batteries to see if this resolves the issue. 5. Defective Film Pack: Cause: Sometimes, a defective film pack can cause the camera to malfunction, including issues with the flash. Solution: Remove the film pack and reinsert it properly, or try a new film pack. 6. Overheating Protection: Cause: If the camera has been used continuously and has overheated, the blinking light could be a protective measure. Solution: Allow the camera to cool down for a while before turning it back on. 7. Internal Camera Fault: Cause: There could be an internal issue with the flash circuitry or other electronic components. Solution: If the problem persists, contact Fujifilm support or take the camera to an authorized service center for further inspection.
