I just recieved your refilable carts for my matte/glossy ink set. Question: Regarding the YouTube demos, are my 7890 carts the same as the 7900 series? One appears to have a bag the other doesn’t?
Regarding my 7890, will I be using a paper clip or syringe to intially fill the channel? Do both your YouTube large format cart vids apply, or is their only one I should follow for my 7890 carts?
