Solving Problems

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.

Contacting a Service Representative

For serious problems, such as the ones mentioned in the previous section, contact your Axiohm authorized service organization to arrange for a service call.
