The printhead may overheat when printing in a room where the temperature is
above the recommended operating temperature or when printing graphics
continuously. In either case, the printer will shut off. See “Appendix A:
Specifications” for information on the recommended temperature range for
operating the printer and on the restrictions of continuous graphics printing.
If the operating temperature is too hot, adjust the room temperature or move the
printer to a cooler location. If the printhead is overheating because of printing
graphics continuously, reduce the demand on the printer.
If the printer continues to overheat, contact your service representative. See
“Contacting a Service Representative” on this page.
No Power to Printer or Power Voltages Incorrect
The power being supplied to the printer is not in the normal range. Check that all
connections are correct. Make sure the power supply is plugged in and that the
printer is on-line.
Contact your service representative if this does not resolve the problem. See
“Contacting a Service Representative” on this page.
Print is Light or Spotty
The printhead may be dirty. Clean it with cotton swabs and rubbing alcohol.
Caution: Do not spray the thermal printhead with household cleaner as this may
damage it and the electronics.
Note: The thermal printhead does not normally require cleaning if the
recommended paper grades are used. If non-recommended paper has been used
for an extended period of time, cleaning the printhead with cotton swabs and
rubbing alcohol will not be of much benefit. See “Recommended Suppliers” on
page 4 for the recommended paper grades.
Contact your service representative if the problem is still not resolved. See
“Contacting a Service Representative” on this page.
