Notes on over-temperature:
A thermistor detects the print head temperature. If the print head temperature exceeds 65 °C, the
user is alerted (over-temperature alert). If the print head temperature exceeds 80 °C, printing stops
(over-temperature shutoff) until the temperature falls below acceptable levels.
