Honeywell PX6i Plus II error 101: Printhead Fault

The Honeywell PX6i Plus II error 101 is a hardware failure code indicating the printer cannot detect or communicate with its thermal printhead. Since the printhead is the engine of an industrial label printer, this error halts operation immediately. Investigating why your Honeywell PX6i Plus II reports error 101 typically involves checking for loose electrical cables or damaged heating elements in the printhead array.

Common causes

  • 1Damaged printhead heating elements.
  • 2Loose or degraded printhead data cable.
  • 3Sensor blockage by label debris.
  • 4Short-circuit on printhead connector.

Solutions

Diagnostic Steps

Error 101 is an electrical fault. If the machine halts immediately on print command, it's often a cable communication issue. If it occurs at startup, the printhead might have a short-circuited heating element.

Troubleshooting Steps

  1. Disconnect all power before touching any internal hardware.
  2. Inspect the printhead cable and re-seat it if needed.
  3. Clean the printhead surface with an approved cleaning tool.
  4. Perform a visual check for broken components or debris in the printhead housing.

Prevention and Maintenance

Regular cleaning is mandatory for industrial printers. Clean the head after each roll of ribbon. Avoid using coarse cleaning materials, which can scratch the thermal surface. Proper ribbon tension also prevents excessive heat damage.

When to Call a Technician

Error 101 often results in printhead replacement. If inspection and cleaning don't resolve the issue, a professional technician needs to verify the logic board signal and the printhead's continuity.

    Test Print

    Run a test label print to check if the error code clears.

Frequently asked questions

It indicates a communication loss with the printhead, often triggered by a damaged cable or failing head electronics.

If it's just a loose cable, yes; but if the printhead elements are burnt out, a replacement is necessary.

Use authentic Honeywell ribbons to ensure the printhead doesn't overheat or degrade prematurely.

After every label roll is the standard recommendation to keep the machine running without errors.
