Recovery from non-HP ink usage 1. Remove the non-HP ink cartridge and replace it with a new one (original HP cartridge). 2. Keep using the same printheads until 9 liters of original HP ink are used for the ink color marked as non-HP. If you insert a new printhead, it will be marked as using non-HP ink because the ink delivery system is marked as having non-HP ink (the following IPS warning message will be displayed): "Using non-HP ink will invalidate the printhead warranty. Press YES to continue or NO to cancel inserting the new printhead and maintain the warranty of the printhead." 3. After consuming 9 liters of original HP ink, the ink delivery system of the respective color recovers and is marked as using original HP ink. The user can now proceed with printhead replacement. IMPORTANT: 9 liters of original HP ink must be consumed in the affected color in order to completely recover from the non-HP ink usage state. Printheads Remove a printhead WARNING!
