Hi, I hope someone can help me, because I don't know what I'm doing.
I caught the fountain pen bug about three years ago and bought several pens -- inexpensive ones to start with. When they developed problems, I tried giving them a thorough cleaning, and I still had problems with them and gave up. My pens have been stored unused ever since.
Something recently sparked an interest again and I decided to give it another try. I flushed and cleaned a Pilot Metropolitan, a Lamy Safari, and two Jinhaos: an X450 and X750. The Pilot and Lamy are writing beautifully now, but I can't get either of the Jinhaos to write at all. I put a "new" cartridge in one and a converter in the other one. (The cartridge is three years old; do they dry up if they've been in the box untouched?)
I need to be educated, please. What can I do to get them working again? I liked them as well as the more expensive pens way back then, and I would like to be able to use them again.
