Low on ink

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 need to replace cartridges until prompted to do so.
For information about replacing ink cartridges, see
Replace the ink cartridges. For information about ordering ink
cartridges, see
Order printing supplies online. For information about recycling used ink supplies, see HP inkjet
supplies recycling program.
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. In addition, some residual ink is
left in the cartridge after it is used. For more information see
