They have one way valves and a filter in the oem cart so it can’t be from the main port. If it ever reports empty to the printer it’s trash. 

You could very likely cut a small hole in the cartridge and bag, seal it to a filler hose and cap. It would likely work. Originally it’s vacuum sealed without air in the bag. 
 

aftermarket carts are about $100 a set delivered, I’d personally suggest that route to avoid problems. 

I have aftermarket carts on the way...just impatient

@johnson4 can the OEM carts be emptied and filled with DTF ink? If so, do you know of any instrictions to do so?
