#1 Detailed Steps: Make a Spongeless Refillable HP Cartridge 61 62 63 64 65 66 67 68 Integrated

HP integrated cartridges are the ones with printhead built-in with the cartridge, such as HP 60, 61, 62, 63, 64, 65, 66, 67, 68 ... Once the cartridge is depleted, HP allows you to keep printing. However, HP will not show ink level anymore. To take this advantage, we modified an OEM cartridge and make it a spongeless refillable cartridge.
