Hi Jim!

I've got the some sort of the same problem as You, with my player
at home, in Norway, and like You, wonders about this phenomena.
My idea, is the quality of the paper used in the roll.

Depending on the evenness of the paper, if it has a smooth surface,
or is more like "paper" -shopping bags, or if it some time has been
moistured and dried again (makes terrible bumps),
It'll more or less suddenly "slide" when it'll be tightened.

My theory is that paper with smooth surface, will be likely to roll
up more evenly, and that paper that is more "textured" more or less
suddenly will "let go" when winding it up.
The reason that it only happens with large rolls, is maybe that the
forces near the center of the roll will be greater, and it more
likely will cause this effect.

This is just my theory, and an idea until some "roll paper expert"
hopefully turns up and can tell us exactly what happens.

Sincerely Thomas Henden (Norway (I hope You understood my English!)

PS!
 NEVER adjust any springs too hard to wind up the paper very
tightly. It will tear the paper on the edges, especially when
the tracking isn't 100% correct. (Which it often isn't.)
On reroll, the spring or whatever, even can be adjusted totally down.
(On footpumpers ) Instead, You pump the roll CAREFULLY back.
On some VERY large rolls however, You need a little tightness,
so all the paper fit with in the flanges of the spool...
The vacuum from the tracker bar holes does the work of holding the
paper in place, although the paper is a little loose winded!
