Checking the temperature reading.
Always measure the temperature of the rolls as close to where the sensor is as possible. The sensor measure the temperature on the bottom roll about 4 inch from the right side. The heat rising from the bottom roller heats the top roller up and will give a false reading. Do not measure through the film as it will give a false reading.

To adjust the heat controls:

To raise temperature

  • Press red button once to display set point value screen
  • Press red button again to raise set point value
  • Hold red button to raise set pont value rapidly
  • Wait five seconds for actual temperature to be displayed

To lower temperature:

  • Press red button once to access set point value screen
  • Press blue button to lower set point value
  • Hold blue button to decrease set point rapidly
  • Wait five seconds for actual temperature to be displayed

To switch from Fahrenheit to Celsius:

  • Hold blue button for five seconds
  • Use red button to change from degrees F to degrees C
  • Wait five seconds for actual temperature to display

Roller Spring Pressure Settings: Professor = Tightens till screw touches the spring the 1 1/2 turns.

What causes the reading F2?
No one knows the exact cause of "F2".
It's one of those mysteries of the Universe.
A. Unplug and plug the ribbon cable back in at both ends.
B. Check the plastic nuts that hold the display.
If the nuts are too tight they cause all kinds of codes.
They need to be just finger tight so they don't twist that board.
They need to be equally tight for this reason as well.
