View estimated ink levels
Follow these instructions to view the estimated ink levels of the print cartridges that are

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 device 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 .
To check the ink levels
1. Open the printer
Toolbox .
