Regarding your answer on item 3 : After weighting all my new 110 ml bottles all are between 138grams-142grams.
[B][I][U]From your documentation I read the following:[/U][/I][/B]
[B][I][U]The circle and rectangle chambers marked below MUST be at least
1/2 filled with ink for proper ink flow. [/U][/I][/B]
[B][I][U]Refill cartridges before ink level reaches 1/2” from the bottom for proper ink flow and to avoid running a cartridge empty. As long
as the circle and rectangle chambers indicated above are at least 1/2 filled with ink, the cartridge does not need to be re-primed. If
the chambers are low or empty, the cartridge must be re-primed to refill the exit channel with ink.[/U][/I][/B]
1- Is this means the ink can be at 1/2 inch from the bottom of the cart, while the two chambers (round & rectangular) above are at least 1/2 full ?
2- Is air can go in the lines if there is still some ink in theses two chambers mentioned in question 1 ?
