Control panel message Description Recommended action
Wrong cartridge in <color> slot The indicated slot for a print cartridge
contains a cartridge that is not the correct
color. From left to right, the print cartridges
should be installed in this order:
● Yellow
● Magenta
● Cyan
● Black
Remove the print cartridge from that slot, and
install a cartridge that is the correct color.
Yellow cartridge low The product indicates when a supply level is
low. Actual print cartridge life might vary.
You do not need to replace the print
cartridge at this time unless print quality is no
longer acceptable. If print quality is no longer acceptable,
replace the print cartridge. Consider
purchasing a replacement cartridge so it is
available when the installed cartridge has
reached the end of its estimated life.
Yellow cartridge very low The product indicates when a supply level is
very low. Actual print cartridge life might
vary. Consider having a replacement print
cartridge available to install when print
quality is no longer acceptable. You do not
need to replace the print cartridge at this
time unless print quality is no longer
acceptable. After an HP supply has reached
the very low threshold, the HP premium
protection warranty for that supply has
ended. If print quality is no longer acceptable,
replace the print cartridge.
