Solutions

Quick Diagnosis

If the printer is struggling to find the start of the label, the 5004 error appears. Verify that the label stock is correctly positioned over the central sensor path.

Step-by-Step Solution

  1. Unload labels and check the sensor path.
  2. Clean optical sensors with compressed air.
  3. Reload label stock making sure it's centered.
  4. Trigger calibration using the printer's menu system.
  5. Check result with a successful print test.

Prevention and Maintenance

Clean sensors during each ribbon/label reload to prevent adhesive buildup and dust accumulation. Using clean, lint-free label stock is highly recommended.

When to Call a Technician

If the error 5004 remains after careful cleaning and repeated calibrations, the sensor component itself is likely faulty.
