Here are a list of things to check:
Run a self test from the printer to determine if the problem is with the printer
Check to make sure that the Film is loaded properly in the cartridge
Ensure that the spools move freely in the cartridge. Check to make sure that the flanges on the film are not binding in the cartridge
Try a different roll of new film
Update your printer driver and firmware to the latest on Fargo’s website
Calibrate the film sensor through the printer driver
Blow out the inside of the printer with compressed air
Try a new updated film cartridge. Fargo Part #D910023
If these steps do not resolve the issue then the film sensor or mainboard must be replaced
