FRM-1120C band sealers are equipped with an ink temperature potentiometer which is attached to a PC
Board. This part controls the temperature that is transmitted to both the ink heating block as well as the
printing wheel. The part is located behind the ink temperature knob. (Figure 40, Item #12) You should
change the ink temperature potentiometer w/ PC Board when both ink heating block and printing wheel
on your band sealer are not achieving optimal heat temperatures.
1. Turn off and unplug your band sealer.
2. Remove ink temperature knob from potentiometer and remove the washer that holds the ink
temperature potentiometer on the panel.
