Check the estimated ink levels
You can check the estimated ink levels from the HP Solution Center, Toolbox (Windows), the HP Printer Utility (Mac OS X), or the embedded Web server. For information about Chapter 9 using these tools, see Use device management tools. You can also print the Printer Status page to view this information (see Understand the printer status page).
NOTE: Ink level alerts and indicators provide estimates for planning purposes only. When you receive a low-ink alert, consider having a replacement cartridge available to avoid possible printing delays. You do not have to replace the cartridges until the print quality is unacceptable.
NOTE: If you have installed a refilled or remanufactured cartridge, or a cartridge that has been used in another printer, the ink level indicator might be inaccurate or unavailable.
NOTE: Ink from the cartridges is used in the printing process in a number of different ways, including in the initialization process, which prepares the product and cartridges for printing, and in printhead servicing, which keeps print nozzles clear and ink flowing smoothly. In addition, some residual ink is left in the cartridge after it is used. For more information, see www.hp.com/go/inkusage.
