I have a number of 1994 Sonnets, which I love. But they tend to dry out overnight, and in some cases an ink cartridge only a couple of weeks old and hardly used has evaporated almost completely. It seems this is a problem lots of people have had. I have read various ideas for solutions on the FPN, and this request is to ask which solution is best. Am I right that it is due to the ventilation holes in the end of the cap being too large?
I have seen the suggestion that dripping candle wax into the inside of the cap can seal the holes. This seems straightforward but I do a fair amount of work in tropical climates and I'm a bit worried about the wax melting. Liquid epoxy has been suggested but wouldn't this be irreversible? Or does that not matter? Or would shellac do the trick?
If anyone has experience of these or any other methods, please enlighten me!
