Check the estimated ink levels
From the Home screen, touch the Ink icon to display the estimated ink levels.
NOTE: 1 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: 2 Ink level warnings and indicators provide estimates for planning purposes only. When you receive
a low-ink warning message, 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: 3 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
