For quite some time I have been filling my colour tanks with a kit
made by Omniwell in Taiwan (
www.omni.com.tw). My source of supply
here in the Greater Vancouver (BC Canada) Regional District has
disappeared. The kits were cheap too, $16 CDN. Is anyone still
selling them in North America?
I find these BCI-21 tanks very easy to fill, just cut the air vent
cover off with an Xacto knife and enlarge the air breather holes so
you could fill from the top. This ink never to my knowledge
contributed to the failure of or plugged a print head.
