5. Maintenance
To ensure the longevity and optimal performance of your replacement nibs and Lenovo Active Pen 3:
- Regular Cleaning: Periodically wipe the nib with a soft, dry, lint-free cloth to remove any dust or debris.
- Avoid Impact: Protect the pen and nib from drops or impacts, which can cause damage.
- Proper Storage: When not in use, store your pen in a safe place where the nib is not subjected to pressure or friction.
- Replace When Worn: Replace the nib if you notice a decrease in performance, visible wear, or if it begins to scratch your screen.
6. Troubleshooting
If you encounter issues after replacing your nib, consider the following:
- Nib Not Responding: Ensure the nib is fully inserted into the pen. Remove and re-insert it firmly.
- Inaccurate Input: Check if the nib is damaged or bent. If so, replace it with a new one.
- Pen Not Working: Verify that your Lenovo Active Pen 3 itself is functioning correctly with its original nib (if available) or another compatible nib. Ensure your device's drivers are up to date.
- Compatibility Check: Double-check that your stylus is indeed a Lenovo Active Pen 3, as these nibs are not universally compatible with all styluses.
