Printer does not recognize a new ink cartridge
If this started right after changing ink, do not reinstall the printer software. First make sure the cartridge is the right one and is fully seated.
Check the cartridge number
Two cartridges can look almost identical but fit different printer families. Use the number printed on the cartridge or package.
Check for packaging
If the cartridge is new, make sure all normal protective tape or shipping material was removed as shown in the printer's replacement instructions.
Reinstall it slowly
Remove the cartridge and put it back into the correct color/slot until it is fully seated or clicks into place.
Close the cartridge door and wait
Give the printer a moment to check the cartridges. If the message clears, try the original print job again.
If the same cartridge is still not detected
Check the manufacturer's support page for your exact model and cartridge number. Avoid cleaning inside cartridge slots unless the manufacturer specifically tells you to.
