In this video, a Canon print cartridge is opened up and revealed not to contain the meagre 11.9 ml (0.4 fl oz) of ink it is advertised. The proposed solution is to buy a printer designed to be manually refilled with bottles of ink (such as the featured Epson EcoTank ET-2850), though it has only been tested briefly.
I hate to be that guy but he doesn’t measure how much ink is actually in the cartridge in the video. He just cracks one open and complains about the ink soaked foam. He could have at least tried to measure how much ink was in it.
How? He can’t weigh it without also weighing the foam.
Could possibly weigh the foam thats soaked in ink then wash the foam to remove the ink and dry it out then weight it again and compare. Might not be very accurate but it would be an attempt at closer numbers at least.
Even then you’re supposedly paying for usable ink. I don’t think the ink will all drop down from the foam.
This can be tested still.
