AC supply voltage is out of
range If paper is not low and no conditions indicate
that the thermal print head is too hot, then it is
likely that the power supply voltage is out of
range.
Contact a service representative if this does
not resolve the problem.
See “Contacting a Service
Representative” later in
this chapter.
Thermal print head temperature
is out of range The print head may overheat when printing in
a room where the temperature is above the
recommended operating temperature or when
printing high-density graphics continuously,
regardless of the room temperature. In either
case, the printer will shut off.
If the temperature of the print head is too hot,
adjust the room temperature or move the
printer to a cooler location. See “Environmental
Conditions” in Appendix
A for the recommended
temperature range for
operating the printer.
If the print head is overheating because of
printing high density graphics continuously,
reduce the demand on the printer.
If the printer continues to overheat, contact a
service representative.
See “Contacting a Service
Representative” later in
