Hi,
	The problem is almost certainly a pressure plate mounting screw
casting a reflective shadow, this will only show when it coincides with
kind-of mid tones in the image, white or black areas - it won't show.
 Quick fix it - use 120 film! 220 only has backing paper at the
 beginning and end of the roll. 120 has backing paper along the whole
 length as you will already know.
Hope this helps,
Cameron.
