Using the Universal 39512 Gel Pen is intuitive:
- Writing Angle: Hold the pen at a comfortable angle, typically between 45 and 90 degrees to the writing surface.

5. Maintenance
Proper care will ensure the longevity and performance of your gel pen:
- Storage: Store pens horizontally or tip-down when not in use to maintain ink flow. Avoid storing them tip-up for extended periods.
- Temperature: Keep pens away from extreme temperatures, both hot and cold, as this can affect ink viscosity and performance.
- Cap Security: Always ensure the cap is securely fastened when the pen is not in use to prevent the ink from drying out.
- Cleaning: If the pen tip accumulates dust or debris, gently wipe it with a clean, lint-free cloth. Do not use harsh chemicals or abrasives.
6. Troubleshooting
Most issues with gel pens are minor and can be resolved easily:
| Problem | Possible Cause | Solution |
|---|---|---|
| Ink skipping or not flowing | Dried ink on tip, air bubble, low ink level, improper storage. | Try scribbling on scrap paper to restart flow. Ensure cap was on. Store horizontally. If ink is low, replace pen. |
| Ink smudging | Ink not fully dry, excessive pressure. | Allow ink to dry before touching. Use lighter pressure. |
| Pen feels scratchy | Debris on tip, damaged tip. | Gently wipe tip with a clean cloth. If tip is damaged, the pen may need replacement. |
