Color ink printer & scanner
Third party ink (black)
20ml
Could refill 2.6 times for my printer cartridge
So, it is easy to calculate the capacity of cartridge:
20 / 2.6 = 7.7 ml
I also brought a larger ink tank from China:
150 ml
150 / 7.7 = 19.5 timesWOW!
There is an air vent on the cartrige but it is too narrow for the injecter. Expand/Ream it.
And tear off the sticker. You will see the air gateway
Prepare for injection
7ml
Done.
Paste a new sticker.
