Here's how you can troubleshoot the issue:

1. Power Cycle the Printer
Turn off the printer and unplug it from the power source.
Wait for about 60 seconds to let the printer reset.
Plug the printer back in and turn it on to see if the error goes away.
2. Perform a Hard Reset
Turn off the printer.
Unplug the power cord from the back of the printer.
Wait for 60 seconds.
Plug the power cord back in and turn the printer back on.
This can help reset the printer’s internal components and may resolve minor software glitches that can cause errors like Error 0.
3. Check the Ink Cartridge Installation
Even though you’ve replaced the ink cartridges, it's still a good idea to double-check that they’re properly installed.

Remove the cartridges and inspect them for any protective packaging (like a plastic strip) that you may have missed.
Reinstall the cartridges, making sure they are clicked into place properly.
Ensure that the cartridge contacts (the small metal or copper contacts) are not obstructed or dirty.
4. Clean the Cartridge Contacts
Dirty or obstructed contacts on the ink cartridges or inside the printer can cause issues:

Turn off the printer and remove the ink cartridges.
Use a soft, lint-free cloth to clean the metal contacts inside the printer where the ink cartridges connect.
Gently clean the contacts on the cartridges as well (using a dry cloth or alcohol-based wipe).
Reinsert the cartridges and try printing again
