QThe message "Incorrect print head type" appears.CLICK

"Printhead" is the name of a part inside a printer.
If you get the error message "The print head type is different," this may be due to a malfunction or deterioration of the printer itself.
This is not a problem caused by the ink cartridge.
The print head wears out and deteriorates with each print.
Sorry to trouble you, but please contact the support window of the printer manufacturer.

QShaking a used ink cartridge produces a sound of ink sloshing around.CLICK

The reason used ink cartridges make a sound when shaken is because the printer is designed to intentionally leave a small amount of ink inside to prevent malfunctions.
Even if you can hear the ink moving when you shake the cartridge, you cannot continue to use it, so please replace the ink cartridge.

QShould I remove the cap?CLICK

If there is a yellow "peel off" tape on the top of the cartridge, please peel it off.
