What Are Common Issues with Fountain Pen Ink Cartridges?

Common issues with Fountain Pen Ink Cartridges include leaking, clogging, and drying out, affecting writing performance and user experience.

Leaking is a common problem caused by improper pen storage or a damaged cartridge seal. Conversely, clogging often occurs due to dried ink residue or foreign particles blocking the ink flow. As for drying out, exposure to air and prolonged periods of non-use can lead to the ink solidifying inside the cartridge.


Leaking in fountain pen ink cartridges can result from improper seating, overfilled cartridges, or temperature changes affecting ink viscosity.

Improper seating causes ink cartridges not to form a tight seal, leading to leaks during use. Overfilling cartridges can create pressure that forces ink out through any available opening. Temperature changes can alter ink flow, causing leakage issues, especially in extreme environments.

To prevent leakage, ensure cartridges are securely placed in the pen to maintain a proper seal. Avoid overfilling cartridges and leave a small air gap for expansion—store pens in stable temperature conditions to maintain ink viscosity consistency.

Particles like dust or fibers can enter the cartridge and impede ink flow. The irregular usage of the pen, such as long gaps between writing sessions, can also contribute to the formation of clogs. It's essential to regularly clean and maintain your fountain pen to prevent these issues from occurring.

Drying Out

Fountain pen ink cartridges can dry out if left unused for extended periods, exposed to air, or subject to environmental factors that accelerate ink evaporation.

One of the primary reasons for ink cartridges drying out is the exposure to air, which leads to the evaporation of the ink. Fluctuations in temperature and humidity levels can also contribute to the drying out of the ink. To prevent this, storing the ink cartridges in a cool, dry place away from direct sunlight and heat sources is essential.

Proper storage practices, such as sealing the cartridges tightly when not in use, can help maintain ink freshness and prevent premature drying.
