Error 5002 Honeywell PX940V Plus: Ribbon motor fault

The Honeywell PX940V Plus error 5002 signals a fault in the ribbon drive system. This error occurs when the printer controller detects that even though the motor is activated, the consumable does not advance as expected or is not detected by the motion sensor. It is a mechanical issue that is usually resolved by adjusting the consumable loading.

Common causes

  • 1Poorly loaded ribbon causing shaft slippage.
  • 2Ribbon sensor obstructed by accumulated dust.
  • 3Physical obstruction in the ribbon take-up mandrel.
  • 4Drive shaft speed sensor failure.

Solutions

Quick Diagnosis

Error 5002 halts the machine as soon as the system detects inconsistency in ribbon advancement. Check if the ribbon is overly tight or too loose, as both conditions can fool the speed sensor and trigger the motor alarm.

Step-by-step Solution

  1. Loading verification: Reinstall the ribbon ensuring the cores are well-seated on the mandrels.
  2. Path inspection: Confirm that the ribbon is not sticking to labels due to static or adhesive residue.
  3. Sensor cleaning: Use a clean, dry swab to remove dust from the ribbon presence sensor.
  4. Shaft test: Ensure the motor can turn the take-up mandrel without excessive resistance.
  5. Reset: Restart the equipment and retry the automatic loading process.

Prevention and Maintenance

Regularly clean the mandrel shaft and sensor area with compressed air. Ensure ribbon cores are of the exact size to prevent slack that causes slippage on the drive shaft.

When to call a technician

If after reinstalling the ribbon and cleaning sensors the printer continues to indicate that the motor is not moving, the drive shaft gear or the stepper motor itself may be damaged, requiring professional service.

Steps to follow

  1. 1

    Check ribbon

    Verify that the ribbon is correctly installed and not loose or torn.

  2. 2

    Check drive shaft

    Gently turn the motor shaft to rule out physical obstructions from dirt or label residue.

  3. 3

    Reset sensors

    Make sure the ribbon sensor is free of dust and correctly positioned.

  4. 4

    Feed test

    Run a ribbon advance cycle to confirm the motor responds correctly.

Frequently asked questions

Error 5002 indicates that the ribbon motor is not spinning or moving at the expected rate. This happens when the ribbon sensor does not detect the movement of the consumable.

It is not frequent. Generally, error 5002 is caused by poor loading of the consumable or a dirty ribbon sensor.

You must use certified ribbons for this model. Using low-cost materials can cause slippage, which is interpreted by the printer as a motor fault.

Yes, the ribbon sensor is optical and collects dust; cleaning it regularly with a dry swab prevents motion reading errors.
