5. Maintenance and Storage
Proper maintenance and storage will extend the life and effectiveness of your thermal labels:
- Storage Conditions: Store unused label rolls in a cool, dry place, away from direct sunlight, high temperatures, and excessive humidity. Extreme conditions can degrade the thermal coating and adhesive.
- Original Packaging: Keep labels in their original packaging until ready for use to protect them from dust and light exposure.
- Handling: Avoid touching the thermal print surface of the labels unnecessarily, as oils from skin can affect print quality over time.
- Printer Cleaning: Regularly clean the print head of your Marklife P50 printer as per its manual to ensure consistent print quality and prevent label jams.
6. Troubleshooting
If you encounter issues while using your MARKLIFE thermal labels, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Labels not sticking properly | Surface is dirty, oily, or textured; label applied incorrectly; adhesive degradation due to improper storage. | Ensure surface is clean, dry, and smooth. Apply firm, even pressure. Store labels in a cool, dry place away from direct sunlight. |
| Print is faint or unclear | Print head dirty; incorrect label loading; labels exposed to heat/light before printing. | Clean the printer's print head (refer to P50 manual). Re-load labels correctly, ensuring the thermal side faces the print head. Store labels properly. |
| Labels getting stuck or jamming | Improper label loading; debris in printer; labels not compatible with printer. | Ensure labels are loaded straight and correctly. Check printer for any debris and clean as per P50 manual. Confirm you are using genuine Marklife 2"x2" labels. |
| Labels fading after application | Exposure to direct sunlight, heat, or certain chemicals; prolonged friction. | Avoid placing labeled items in direct sunlight or near heat sources. Protect labels from abrasive contact. |
