If it is the same paper that I am currently using -- it sounds the same, but I don't have the part number in front of me -- then I have found that it is extremely difficult to soak the paper off. OTOH, I have had very good results if I peel the paper off immediately after the last pass through the laminator while everything is still very hot. It peels off, leaving the toner behind.* It also leaves a white residue on top of the toner, but this does not interfere with etching at all.

*I often get one or two small "specks" per board that stay with the paper rather than on the board -- especially on larger traces/pads/ground planes -- but it is easy to see exactly where I need to do a little touch up with a pen by looking at the paper. I tended to get similar specks/defects using other paper and soaking off, but I couldn't always tell easily where the problem would be.
