Important Compatibility Note

• Some compatible HP printer models may reject compatible cartridges if Dynamic Security, firmware-based cartridge checks, or similar chip-based recognition systems are active.
• HP states that some printers are designed to work only with cartridges that use a new or reused HP chip or matching HP electronics.
• This is a known printer-side compatibility limitation and is not automatically considered a cartridge defect.

Possible Errors & Troubleshooting

• If messages such as “Cartridge Problem”, “Incompatible Ink Cartridges”, “Incorrect Ink Cartridge”, “Used or Counterfeit Cartridge Detected”, or “not communicating” appear, remove the cartridge and reinstall it carefully.
• Check that each cartridge is inserted correctly and fully locked into place.
• Make sure all protective films, seals, and transport protections have been removed before installation.
• If necessary, carefully clean the chip and contact area with a dry lint-free cloth.
• If the printer shows messages about an unrecognized chip, non-original cartridge, or incorrect communication, printer-side Dynamic Security, firmware, or similar HP controls may be involved.
• If print quality is poor after the cartridges are recognized, perform the usual maintenance steps such as printhead cleaning and alignment, if supported by the model.
• Contact Plutoos support if the problem persists.
