Anyone know what kind of ink used to refill the HP print cartridge?

I want to refill the cartridge by myself. But I don't know what kind of ink and tool I have to buy. Any instruction. Thank youAnyone know what kind of ink used to refill the HP print cartridge?
The kind of ink is not depicted by the manufacturer of the printer. Almost any refill kit you can purchase today will work in any printer. When you order the refill kit it will come with a small drill bit, probably inside a small wire nut handle. On the top of the cartridge is a breather hole. Use the bit to enlarge the hole so that the syringe fits in it, and fill until the ink no longer is absorbed into the cartridge. You may want to fill it, let it set a bit, then fill it again after the matting absorbes some of the ink. When it is full, you will know, as it will not take any more. To clean up the mess you are going to make have a bottle of acetate (common finger nail polich remover) on hand. It would be a good idea to use the acetate with a lint free towel like Scott's brand and clean the nozzles at the same time. Remeber that acetate will ruin most surfaces like table tops, etc. Hope this helps.Anyone know what kind of ink used to refill the HP print cartridge?
