Low on ink
The ink cartridge identified in the message is 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 on page 99. For
information about ordering ink cartridges, see Order ink cartridges on page 101. For information
about recycling used ink supplies, see HP inkjet supplies recycling program on page 178.
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
