For optimum results from your printer and the ink system, always follow these guidelines when handling the HP supplies:

• Install the ink cartridges, printheads and printhead cleaners before the install-by date, which is printed on the packaging.
• Install a new printhead cleaner every time you change a printhead.
• Allow the printer and printhead cleaners to clean the printheads automatically.
• Install ink cartridges, printheads, and printhead cleaners in their color-coded slots.
• Follow the instructions on the front panel during installation.
• Avoid unnecessary removal of the ink cartridges and printheads.
• When turning off your printer always use the Power Off button on the front panel. The printheads are then stored correctly, which prevents them from drying out.
• The ink cartridges should never be removed while the printer is printing. They should be removed only when the printer is ready for you to replace them. The front panel will guide you through the removal and installation procedure. See how do I use the ink cartridges?

Caution: when you first received your printer it was supplied with a set of six setup printheads installed in the printhead carriage. These setup printheads are used for the priming of the tubes in the modular ink delivery system. Do not remove the setup printheads from the carriage without following the procedures in the Setup Instructions.
