I have a 6x7 Linhof Super Rollex that sometimes leaves me with a line on one (more rarely two) ends of the neg. This is a line line of increased density that is perhaps two millimeters in from the 56mm edge. It has only happened with wide angles (47 and 65mm SA) and only in bright conditions, so I suspect that it a reflection of the shiny film transport roller(s).
This problem is a real pain, as I try to format through to the edges, to get the maximum benefit of the negative size. Are all Super Rollexes subject to this problem, or are the later ones better ? Is there a fix for this problem that is better than what I've already done - blacken the rollers with an indelible pen ?
