Introduction

A printhead assembly is formed by cartridges fitted into printheads. A new printhead assembly needs to be installed when the existing printhead assembly is damaged or is incompatible with the product. Replacement printhead assemblies are only available from HP Support or authorized service providers.
NOTE:If HP replaces your printhead assembly under warranty, you will receive a new printhead assembly, cleaning materials, and a full set of new cartridges. If your printhead assembly is no longer under warranty, you can purchase a new one online . Click the link, and then look for the HP Parts Store. Search for part number CN642A. If the HP Parts Store is not available, contact your local HP sales office. The new printhead assembly comes with cleaning materials. To avoid possible damage to the new printhead assembly, also buy new cartridges.
