All your images have that dark line on them, you just don't see it in the ones with a dark lower right corner. It is a hair or fibre in your camera in front of the shutter, or just behind it in front of the film plane. Should be easy to remove. The random white lines are debris - the scans were obviously done by a beatnik who knows nothing about dust blowers.
