Hi @Zozo2005,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

The error code OXC4EB9556 HWLMICCI2 C on HP printers typically indicates a firmware or hardware-related issue, often involving the printhead, ink system, or internal electronics. Here are some general steps you can try to resolve it:
 

🛠️ Fix Steps for Error Code OXC4EB9556

1. Power Reset the Printer
   • Turn off the printer.
   • Unplug the power cord from the printer and the wall outlet.
   • Wait for 60 seconds.
   • Plug the power cord directly into a wall outlet (avoid power strips).
   • Turn the printer back on.
      
2. Check for Paper Jams or Obstructions
   • Open all access doors and remove any paper jams or foreign objects.
   • Make sure the carriage can move freely.
      
3. Remove and Reinsert Ink Cartridges
   • With the printer on, open the ink cartridge access door.
   • Remove all cartridges and inspect them for damage or ink buildup.
   • Reinsert them securely.
      
4. Update Printer Firmware
   • Go to HP’s official support site and enter your printer model.
   • Download and install the latest firmware update.
      
5. Reset the Printhead (if removable)
   • If your printer has a removable printhead, take it out and clean the electrical contacts gently with a lint-free cloth.
   • Reinstall it and restart the printer.

I hope this helps.

Take care and have a good day.
