The manual is lost for this machine and i need to know about the temperature setting and also what the small black switch that is numbered 1 2 3 // with 2 slanted lines is for. I have it on NAP 1 because I have 1.5 lam but the temp is only at 79. I am getting wrinkles. The actual roll of paper has some dents in the roll and this is probably why, but I want to run it at a higher temp to see if creases come out. Thank you
