How do I replace just one CMYK colour?

Each colour is independent. Replace only the cartridge of the empty colour and leave the other three in place: the printer automatically detects the new one and syncs it.

How to install?

Turn off the printer and open the front door.
Identify the four CMYK cartridges by color or label.
If your model separates toner and drum, remove the assembly and separate the cartridge from the drum (do not touch the green roller).
Remove the used cartridge, shake the new one 5 times, and remove the pull-tab.
Insert the cartridge into the correct color-coded position.
Close the cover, turn on the printer, and wait for chip synchronization (typically 60 seconds).

Do I lose my printer warranty?

No. Art. 120 of RDL 1/2007 and Directive (EU) 2019/771 prohibit manufacturers from voiding your warranty for using compatible consumables. According to Directive (EU) 2024/1799 on the right to repair (in force July 31, 2026), the use of compatible cartridges does not affect the manufacturer's warranty.
