Ok, I found it's look like the issue described here :
http://www.apug.org/forums/forum44/7...oid-550-a.html

I understood there is a relation with the white tab, for sure, since the clearer mark in the center seems to have the same width as the white tab.

So I probably don't loaded the pack correctly.
If I read the above thread, Matt S said "the white tab does NOT go through the rollers".

But WHERE the hell it have to go ? How the white tab can pull the larger "Color Tab" (as Fuji documentation call it) or "Yellow tab" (Polaroid doc) between the rollers, else ?

Totally confused, now
