This is a stubborn problem. I put black tape over the edges of the opening in the negative stage. See pictures of the mod below. The stray lights didn't go away.
I put a paper mask on half of the negative carrier (above the negative) and the stray lines disappear on one half of the baseboard.
I also tried moving the bellows up and down and that didn't move the stray lines. Therefore it doesn't seem like the bellows causing it.
I also checked the inside of the bellows carefully. Its matt black with no real shiny edges.
Is this some sort of diffraction?
