Note All eight cartridges and four printheads must be correctly installed for the printer to work. If this is the first time you are installing the ink cartridges and printheads, see the Quick Start guide for information on the initial set up of ink cartridges and printheads. If you need to replace the printheads, see Replace faulty printheads.
Follow these tips to help maintain HP ink cartridges and ensure consistent print quality:
●Keep all unused ink cartridges in their original sealed packages until they are needed. Store ink cartridges at room temperature
Note Each ink cartridge has an expiration date. When you receive an ink expiration message, you can continue printing by pressing OK on the control panel. HP recommends replacing the expired ink cartridges. HP cannot guarantee the quality or reliability of expired ink cartridges.
●Do not remove the plastic tape covering the gold contacts until you are ready to install the ink cartridge in the printer. If the plastic tape has been removed from the ink cartridge, do not attempt to reattach it. Reattaching the tape damages the ink cartridge.
Replace faulty printheads
If a message appears on the printer screen directing you to replace a printhead, try cleaning the printheads. See Clean the printheads automatically. If you still see the message on the printer screen after you have cleaned the printheads, call HP support. If the support staff tell you that the printhead needs to be replaced, purchase a replacement printhead, and then follow these steps. To purchase replacement printheads, go to:
