It depends on what is causing the issue. If it happened right after you put in a cartridge, then it is probably that it hasn't been able to saturate the feed yet. A few shakes will help. If it has been inked, but stopped writing, then a quick dip of the tip in water could work. If this doesn't work let me know.
It might be the ink. There are some dip pen inks that are lacquer based and could cause some real havoc.
Edit: we posted at the same time. I think it is because it wasn't flushed. Some gunk could have gotten in the feed. When this cartridge runs out, just clean it well, and you should be good. This has happened to me before too. Once I cleaned it, it was good to go.
Will do, thanks.
