Remedial questions that weren’t clear to me reading the instructions for filling and using the Conecolor ink cartridges.
In step 9, you remove the vent hole plug. It doesn’t say to replace it, does this remain open for operation?
In step 13 you insert the priming tip into the ink outlet to prime it. Do you just jam the priming tip through the thin clear plastic cover of the opening or do you remove that plastic?
