  • PrintPrint

Introduction

This document provides information on how to replace a printhead or ink cartridge.
A printhead may need replacing when print quality issues cannot be resolved by cleaning the printheads or a front-panel display message indicates a printhead needs to be replaced.
An ink cartridge needs replacing when a front-panel display message indicates either:
  • Low ink levels
  • Ink cartridge approaching expiration date
CAUTION:Never remove an ink cartridge and a printhead at the same time.
NOTE:HP has developed a short video to assist in completing this procedure. Viewing this video requires Microsoft Windows 98 or newer with Microsoft Internet Explorer, and a high-speed Internet connection. Click here to view the Replace Printhead and Ink Cartridges video .
