What should I do if the printer displays a 'Cartridge is low' or 'Cartridge is very low' message?

This message displays on the printer control panel or the HP Embedded Web Server (EWS) when toner is running low. The manual addresses this issue in the troubleshooting section and provides guidance on replacing toner cartridges. You can also order replacement supplies through the ordering information provided in the Supplies, accessories, and parts chapter. (Page 129)
