2.1 Self-diagnostic Test

The status of the Print Head Thermistor, Ambient Temperature Thermistor, Black Mark Sensor, and Feed Gap Sensor, Print Head resistance rank, and print head resolution are printed.

SENSOR2 [H]23°C [A]22°C [R]4.2V [T]2.5V

Feed gap sensor status: 0.0 to 5.0V

Black mark sensor status: 0.0 to 5.0V

Ambient temperature thermistor status: 0°C to 86°C

If it is undetectable, “--°C “ is printed.

Print head thermistor status: 0°C to 86°C

Print status description

A thermistor built in the print head detects a print head temperature. The current supplied to the print head (= print tone) is controlled on the basis of this temperature.

When the print head overheats (80°C or over), the printer displays “EXCESS HEAT TEMP” message and stops printing to protect the print head.

Temperature inside the printer (around the media) is detected. The current supplied to the print head (= print tone) is controlled on the basis of this temperature. When the temperature of 61°C is detected, an error message, “EXCESS HEAT TEMP”, is displayed and the printer stops.

Real time voltage detected by the black mark sensor is displayed/printed.

Real time voltage detected by the feed gap sensor is displayed/printed.

There is individual variability in average resistance of the thermal element. The current supplied to the print head is controlled on the basis of this value to obtain the optimal print tone.
