White ink "Expiry date"

Post by willkho » Wed Oct 11, 2017 2:09 am

Hi all,

I've been using Bn-20 with white ink (eco-solmax 2) for few years. I always shake it and try to print with it every week (just to circulate it).
So far so good, I only experience problem normally when it ink is about to finish.
I'm not printing with white ink regularly so it takes a while to finish a cartridge.

-Is there any "expiry date" on the white ink? The white seems to be very milky (not opaque) when it's somewhere below 20% ?
- Sometimes the cartridge (near the insertion point of the cartridge) is somehow melt. I believe it's because of the solvent damaging the plastic. I heard the rule of thumb is about 200 times insertion , is this true?

thanks all.
