Setup
The Pentel EnerGel RTX pen is ready for immediate use upon removal from its packaging. No assembly or initial setup is required.
- Remove the pen from its packaging.
- Ensure the tip is free of any protective covering (though typically none is present for this model).
- Click the top button to extend the pen tip.
Operating Instructions
Using your EnerGel RTX pen is straightforward:
- Extend the Tip: Press the push-button mechanism at the top of the pen until the tip extends and locks into place.
- Writing: Hold the pen comfortably using the latex-free grip. Apply light pressure to the paper as you write. The liquid gel ink flows smoothly, providing clear and consistent lines.
- Retract the Tip: When finished writing, press the side clip or the push-button again (depending on the specific mechanism) to retract the pen tip into the barrel. This protects the tip and prevents accidental marks.

Maintenance
To ensure the longevity and optimal performance of your Pentel EnerGel RTX pen:
- Refilling: The EnerGel RTX pen is refillable. When the ink runs out, replace the ink cartridge with a genuine Pentel EnerGel refill (any size/color EnerGel refill is compatible). To refill, unscrew the barrel, remove the old cartridge, insert the new one, and screw the barrel back together.
- Storage: Store pens with the tip retracted to prevent drying out or accidental marking. Avoid storing in extreme temperatures.
- Cleaning: If the pen barrel or grip becomes dirty, wipe it gently with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Ink not flowing smoothly or skipping. | Ink cartridge is empty or nearly empty; tip is clogged; pen has been stored improperly. | Replace the ink cartridge. Gently tap the pen tip on a piece of scrap paper to dislodge any clogs. Store the pen horizontally or tip-down. |
| Pen tip does not retract or extend properly. | Mechanism is jammed or damaged. | Ensure no foreign objects are obstructing the mechanism. If the mechanism is damaged, the pen may need to be replaced. |
| Ink smears after writing. | Ink has not had sufficient time to dry; writing on highly non-absorbent paper. | Allow a few seconds for the ink to dry, especially on glossy surfaces. EnerGel ink is fast-drying, but extreme conditions or certain paper types may require more time. |
