Hi there, If you're using a Windows computer please follow the instructions below. 1. Make sure your printer is on and connected to the computer/device. 2. Double-click the HP Digital Imaging Monitor on the Windows taskbar located at the bottom of the screen, if it's not there search for the 'HP solution center' in the search bar. 3. Once in the HP solution center click Settings and then click Printer Toolbox. 4. When the toolbox is open click the 'Estimated Ink levels' tab to view all of the cartridge's ink levels. If you need any further assistance please call 0345 365 3605 or email
