Any ink releated part May cause This. You need to clean all parts and check if they block any liquid flowing. If they still block liquid flow, you need to replace those parts.

Last option is maybe your ink gone bad and re-cloging dampers.

 

Yea, ink was something that I left out. I have some that’s been expired for 6 months and works fine though.

On peak conditions most inks are usable for a year, after they manufactured not after when you buy.

Peak conditions:

Room tempature

Humidity

If inks are shaken everyday

Inks should not get sun light

inks should not interact with Air for too long

inks should not get any dust in it

you should clean bottles and ink tanka regularly from solid inks.

The ones that have been expired are from expiration date. I never shake my Cmyk, I should probably start, lol.
