Yes, it's probably mostly from the magnetic stripe, since what comes off on a Q-tip is usually brown. I do suspect some emulsion dust, too, however. After the gate, the most shows up under the second sprocket -- on the green guide notorious for scratching.
Eumigs rarely show much dust on the projected image, which lulls you into being remiss with cleaning the gate! But we know better!
