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 tab.
- Insert the cartridge into the correctly color-coded position.
- Close the cover, turn on the printer, and wait for chip synchronization (typically 60 seconds).
Will I lose my printer's warranty?
Your Startoner consumable is covered by a three-year legal conformity guarantee. Printer coverage is governed by the manufacturer’s terms and may exclude damage caused by consumables. Using a compatible cartridge does not by itself establish the cause of a fault; keep your documentation and contact us if a problem occurs.
If your HP printer shows "non-original cartridge" after an HP Dynamic Security update, do not update the firmware while using compatibles. If it persists, we can help: your cartridge has a 3-year legal warranty.

Does it have a chip and will my printer recognize it?

How do I change only one CMYK color?
Each color is independent. Only replace the cartridge of the exhausted color, leaving the other three in place: the printer automatically detects the new one and synchronizes it.
