Situation: Printing/Media feed
1. “HEAD TEMP” is displayed when printing is attempted.
Possible cause Check point Solution
Print data of high printing
ratio was printed.
• When ratio of print to media is high, the
print head temperature rises. In this case,
“HEAD TEMP” may appear.
For safety, when the print head
temperature reaches about 71°C, the
printer stops, resulting in an error.
• If a foreign object is attached to the print
head, the print head can overheat.
• If this error occurs even if no printing is
performed, there could be other causes.
Allow the print head to cool.
Change the print data or printing speed.
Clean the print head.
Ambient temperature is
over 60°C.
This error occurs when the ambient
temperature, detected by the thermistor
mounted in the printer, is over 60°C.
Even if the ambient temperature is less than
60°C, “HEAD TEMP” error may occur ,
when the room temperature is 40°C or over,
depending on the installation location or
operating conditions.
If this error occurs when using the printer in
a specified temperature range, there could
be other causes.
Use the printer in the specified
temperature range (0°C to 40°C).
Change the installation location or
operating conditions.
