Hex Code 02 Thermal
Head temperature error.
Ensure that the thermal head is warmed up to operational
level. The thermal head unit should feel warm to the touch;
don't touch the printing elements. If the thermal head is cold,
check power connections and the power supply.
If the power connection and power supply feels too hot,
ensure that the thermal head fan and two small internal fans
are operating correctly. They should run during printing and
while the thermal head temperature is above 35
o
C (95
o
F).
Also check that the engine fan blows outward (into the card
cage) and the thermal head fans blows upward.
Ensure that the cable to the transfer roll mark sensors and
thermistor, which senses ambient temperature, is functional.
Ensure that thermal head resistance value, set by DIP
Switch 2, is correct. Refer to the Chapter 9 topic “Adjusting
for best printing quality.”
Are the thermal head cable connectors functional?
If everything else checks out, replace the thermal head.
Refer to the Chapter 8 topic “Thermal head” on page 8-18.
If the thermal head and power supply check out, replace the
print engine control board. Refer to the Chapter 8 topic
“Engine control board” on page 8-40.
