I have been using an automated lab service (Fuji products) to develop my film (until I get my darkroom set up) and have been getting negs and prints back with a light band going vertically through the images. The color shows up red on the prints.

I first thought that I had a light leak in the camera. But it doesn't occur on every frame. and they are not the same intensity. Some bands are very strong while others are faint. The occurance goes all the way from one edge to the other of the negative, which tells me that its not coming from the lens side of the camera.

Someone told me that it may be the developer/processor; a dirty roller or something. Has anyone seen this before?

See scan of negative...
