Yes, now I see it (saved the jpegs and cranked magnification up to 400% in PS). And, sorry, but I have no idea of where it may come from... The obvious solution is to scan with bp=0% and modify the image later in PS with levels or curves (which also gives you more flexibility), but I understand that this is no answer to your question. BTW, what Vuescan version are you using?
