Liquid ejecting head and liquid ejecting device

A liquid ejecting device, comprising:

• an actuator communicating with a nozzle and configured to eject liquid from the nozzle;
• a drive circuit configured to drive the actuator;
• a flow path of liquid circulating;
• a wiring connector on a circuit board having a plurality of terminals;
• a first temperature sensor configured to measure a temperature on a surface on the circuit board proximate to the drive circuit and connected to a first terminal of the plurality of terminals;
• a second temperature sensor configured to measure a temperature of a liquid on the flow path of liquid circulating and connected to a second terminal of the plurality of terminals;
• and
• a control board configured to:
• stop a printing operation if a first temperature value determined based on a signal supplied via the first terminal is outside of a first predetermined allowable range,
• not apply a drive voltage to the drive circuit if a second temperature value determined based on a signal supplied via the second terminal is outside of a second predetermined allowable range and the first temperature value is within the first predetermined allowable range, and
• apply a drive voltage to the drive circuit if the second temperature value is within the second predetermined allowable range and the first temperature value is within the first predetermined allowable range.
