Previously used ink cartridge installed
The ink cartridge identified in the message was previously used in a different printer.
You can use ink cartridges in different printers, but if the cartridge was left outside of a printer for
an extended period of time, the print quality of your documents might be affected. Also, if you use
ink cartridges that have been used in a different printer, the ink level indicator might be inaccurate
or unavailable.
If the print quality is unsatisfactory, try cleaning the printheads. For more information, see To
clean the printheads.
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 printer 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.
For more information about storing ink cartridges, see Supplies.
