1. Hold your FEP film towards the light to check to see if it is scratched or damaged. If the FEP film is scratched or uneven, it may be able to function normally though you should perform a test print to see if it produces any errors while printing. If it does, you should change your FEP film promptly.

2. If your FEP film has a bump on it, it may be damaged and you should replace your FEP film as soon as possible.
