Identify what ink your mky buys. ​1. Please buy MKY(PIG) when using the original MK ink cartridge. ​2. Please buy MKY(DYE) to use renewable compatible ink cartridges.

Use the original chip and brand-new print head to ensure 100% recognition. If there is no recognition, determine whether it is your machine problem or contact our customer service.Machines that use continuous supply ink cartridges can easily cause the pipeline to lack ink, causing the print head to deny the machine.
