3. Setup and Ink Filling
3.1 Initial Inspection
Before first use, carefully inspect your Asvine J16 fountain pen for any visible damage. Ensure the nib is properly seated and the piston knob turns smoothly.
3.2 Piston Filling Procedure
The Asvine J16 utilizes a piston filling mechanism, designed for use with bottled ink (ink not included). This system allows for a high ink capacity.
- Prepare Ink: Ensure you have a bottle of non-carbon bottled ink.
- Extend Piston: Unscrew the knob at the end of the pen barrel counter-clockwise until the piston is fully extended towards the nib. Do not force the knob if it stops moving, as this indicates it has reached its end and forcing it can damage the piston system.
- Immerse Nib: Fully immerse the pen's nib and a portion of the grip section into the bottled ink. Ensure the ink covers the breather hole on the nib.
- Draw Ink: Slowly turn the knob clockwise to retract the piston, drawing ink into the pen's reservoir. Observe the ink filling through the transparent ink window.
- Remove Excess Ink: Once the reservoir is full, remove the nib from the ink bottle. Turn the knob slightly counter-clockwise to expel a few drops of ink back into the bottle, then turn clockwise again to draw the ink back in. This helps to clear any air bubbles and ensures a clean feed.
- Clean Nib: Gently wipe any excess ink from the nib and grip section with a soft, lint-free cloth or tissue.

5. Care and Maintenance
Proper care and maintenance will ensure the longevity and optimal performance of your Asvine J16 fountain pen.
5.1 Regular Cleaning
It is recommended to clean your fountain pen regularly, especially when changing ink colors or if the pen has not been used for an extended period.
- Empty Ink: Expel any remaining ink from the pen by turning the piston knob clockwise until the reservoir is empty.
- Flush with Water: Immerse the nib and feed into a glass of clean, cool water. Operate the piston mechanism repeatedly to draw water into and expel it from the pen until the water runs clear.
- Dry: Gently blot the nib and feed with a soft, lint-free cloth. Allow the pen to air dry completely before refilling or storing.
5.2 Deep Cleaning and Disassembly
For a more thorough cleaning or if ink flow issues persist, you may disassemble the nib unit using the provided wrench.
- Use the wrench to carefully unscrew the nib unit from the grip section.
- Rinse the nib, feed, and grip section under cool running water.
- Allow all components to dry completely before reassembling.
- Ensure the nib and feed are correctly aligned when reinserting them into the grip section.
5.3 Storage
When not in use, store your Asvine J16 fountain pen capped to prevent the nib from drying out. Store it horizontally or nib-up to prevent ink from pooling in the cap.
6. Troubleshooting
Below are common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No ink flow or skipping | Dried ink in feed, clogged nib, low ink level, or incorrect ink. | Flush the pen thoroughly with water. Ensure sufficient ink. Use appropriate fountain pen ink. |
| Pen dries out quickly when capped | Cap not sealed properly. | Ensure the cap is screwed on tightly. Inspect the cap for any cracks or damage. |
| Piston knob is stiff or stuck | Dried ink or debris in the mechanism. | Do not force. Flush the pen with water. If persistent, disassemble carefully with the wrench and clean. |
| Ink leakage | Overfilling, damaged seal, or extreme temperature changes. | Avoid overfilling. Inspect seals. Avoid leaving the pen in direct sunlight or extreme cold. |
