Dear HoyeBoye !

I did everything just like in the description, but my printer does not detect any of the toners. Do you have any idea what should I do?

Thank in advance,

I’m afraid I don’t have any further suggestions. If you are trying to re-fill an old toner cartridge, the cartridges have an embedded chip that prevents re-use.
