Not true... with manual screen load machines (LT / Horizon), you need to ascertain the correct position / measurement and can load to that position. Auto load machines there is a "custom screen" setting which is used to tell machine the position ("Di

Most of this you have probably covered, but these are what have caused heating issues for us in our 1707 EXL. First, you would probably notice, but check that all blowers are turning by looking at there cooling fans in the top and bottom, Our 170
