When replacing ink cartridges in your Hewlett Packard printer, occasionally the original or remanufactured HP 302 or 304 ink cartridge will not be recognised. The full message is likely to read…
“Remove and Reinstall the Indicated Cartridge, making sure it is correctly installed.”
Whilst this can normally be resolved with some simple troubleshooting (like that found here), it can be difficult to determine which cartridge your printer has a problem with.

What does each symbol mean?
With the 302 and 304 ink cartridges, Hewlett Packard indicate whether it is the black or colour cartridge with a small symbol found under the “The Following Ink Cartridge must be replaced” message. From the black and white symbols alone, it is not always particularly obvious which cartridge needs changing, especially with compatible or refilled cartridges that no longer have the original label.
Which symbol represents the black and tri-colour cartridge is shown on the aforementioned label and for this range, but we have detailed which represents which below…

A single large dot indicates the black cartridge, but the tri-colour cartridge is shown as three smaller black dots. The colour symbol represents the cyan, magenta and yellow ink within, but is somewhat misleadingly shown as a black symbol still, due to the limitations of the monochromatic screens used by some of these printers.
Which printers does this relate to?
This advice relates to the HP 302 Black (F6U66AE), HP 302XL High Capacity Black(F6U68AE), HP 302 Tri-Colour (F6U65AE) and the HP 302XL High Capacity Tri-Colour (F6U67AE) ink cartridges. These ink cartridges can be used in the printers below.
