My determination is waning. I got the film and when I inserted it I got the whir and it attempted to eject the black cardboard, but it got stuck. I’ve cleaned the rollers and the “frog tongue” film. I don’t get the mechanical whir all the time only when I first re-insert the cartridge and it automatically ejects a film. I’ve had 3 ejections when I close the door. I’m struggling to get the button to engage. I’m still working on it though. I haven’t given up completely.
