Checking Ink Levels for HP Officejet J6400 All-in-One Printer Series

Check the ink supply level to estimate the amount of ink remaining in the print cartridges, and to determine how soon a print cartridge needs replacement.
Ink level warnings and indicators provide estimates for planning purposes only. When an indicator shows low-ink levels, consider having a replacement cartridge available to avoid possible printing delays. You do not need to replace cartridges until print quality becomes unacceptable.
Checking ink levels
Use one of the following methods to check the ink levels.
The ink level is displayed on the main screen of the control panel display. Locate the two icons that represent the print cartridges. The icon on the left is for the color cartridge and the icon on the right is for the black cartridge.
  • The exclamation mark (!) symbol indicates a low ink level.
  • The question mark (?) symbol indicates the product cannot determine the status of the print cartridge. This might be because the cartridge is refilled.
