Honeywell PX45s error err-print-temp: Troubleshooting

The Honeywell PX45s error err-print-temp triggers when the printhead thermal sensor detects temperatures exceeding safe operating limits. This safety shutdown is designed to protect the heating elements from damage caused by rapid printing in high-heat environments. Swift diagnosis is necessary to keep your labels flowing efficiently.

Common causes

  • 1Excessive heat buildup from continuous high-speed printing.
  • 2Accumulation of adhesive residue on the printhead surface.
  • 3Darkness setting is pushed beyond material specifications.
  • 4Hardware failure of the printhead temperature thermistor.

Solutions

Quick Diagnosis

If you see the err-print-temp code, the machine has paused to prevent hardware damage. Check if the environment is too hot or if there is excessive adhesive buildup on the head.

Step-by-Step Solution

  1. Power down the machine for at least 15 minutes to allow for cooling.
  2. Open the printhead and inspect for adhesive debris.
  3. Clean the printhead surface with a lint-free cloth dipped in high-purity isopropyl alcohol.
  4. Reduce the 'Darkness' or heat settings in your driver software if using thick stock.

Maintenance and Prevention

Perform printhead cleaning every time you load a new ribbon. Ensure at least 4 inches of clearance around the printer for ventilation. Only use manufacturer-approved ribbons to ensure smooth media passage.

When to Call a Technician

If the error occurs immediately upon startup, the internal temperature sensor may be failing, necessitating a full printhead assembly replacement.

    Lower the print heat settings if the error recurs.

Frequently asked questions

It signals that the printhead has exceeded operating temperature limits due to high-intensity work.

Ignoring the heat alert can cause permanent printhead damage.

Always use original Honeywell thermal ribbons to minimize friction.

Use a specialized cleaning pen or lint-free cloth with 99% alcohol.
