 This is a quick update from BCH. For 902 cartridges, HP had some modification of their cartridges design. Let's take a look at the regular start-up black cartridge. We're not talking about this XL cartridge. Let's take a look of a start-up cartridge. We're surprised that it has the opening between the front and back chambers. Furthermore, please see the ink stand on the wall of the back chamber. It means the HP is using the back chamber just like the XL cartridges. This is good news because we can refill regular or start-up black by refilling from the back chamber now. For the color start-up cartridges, HP expanded sponge makes it a lot longer. Now the back chamber is gone and the whole cartridge is a big piece of sponge. Therefore, for the color start-up cartridges, we should use front chamber refill. For the black start-up cartridges, we can use either front chamber refill or back chamber refill. I hope you enjoyed this video.
