5. Maintenance and Storage
To ensure the best performance and longevity of your MARKLIFE Direct Thermal Labels, follow these maintenance and storage guidelines:

- Handling: Avoid touching the thermal printing surface of the labels with bare hands as oils and dirt can degrade print quality.
- Printer Care: Regularly clean your Marklife P50 printer's print head according to its manual to prevent dust or adhesive residue from affecting print quality and label feeding.
6. Troubleshooting
If you encounter issues while using your MARKLIFE Direct Thermal Labels, consider the following common solutions:
- Faint or Unclear Prints:
- Ensure the label roll is inserted correctly with the thermal printing surface facing the print head.
- Check if the printer's print head is clean. Refer to your printer manual for cleaning instructions.
- Verify that the label roll is not expired or damaged from improper storage (e.g., excessive heat exposure).
- Labels Not Feeding Correctly:
- Confirm the label roll is properly seated and aligned within the printer's guides.
- Check for any obstructions or debris in the label path.
- Ensure the printer's rollers are clean and free of adhesive residue.
- Labels Not Sticking:
- Ensure the application surface is clean, dry, and smooth.
- Avoid applying labels to extremely textured, oily, or dusty surfaces.
- Check the storage conditions of the labels; prolonged exposure to high humidity or heat can degrade adhesive.
- Printer Not Detecting Labels:
- Ensure the labels are "gap labels" compatible with your Marklife P50 printer's sensor.
