Hi @fanender123 

Welcome to HP Support Community.

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

The 63.00.34 toner cartridge error on your HP LaserJet MFP E78223 indicates an issue with the toner cartridge or toner cartridge sensor. This error is typically related to a problem with how the printer is detecting or communicating with the toner cartridge. The issue could be due to a faulty toner cartridge, dirty sensors, or a connection problem between the toner cartridge and the printer.

Here are steps to troubleshoot and resolve the 63.00.34 toner cartridge error:

1. Check and Reseat the Toner Cartridge

• Turn off the printer and open the toner cartridge door to access the toner cartridges.
• Remove the toner cartridge carefully.
• Inspect the toner cartridge for any damage, leaks, or missing components.
• Reinstall the toner cartridge securely back into the printer, ensuring it clicks into place. Sometimes, an improperly seated cartridge can cause this error.
• Close the toner door and turn the printer back on to see if the error clears.

2. Clean the Toner Cartridge Contacts and Sensor Area

• Turn off the printer and remove the toner cartridge.
• Look for the metal contacts on the toner cartridge. These contacts are used for communication between the cartridge and the printer. Gently clean the contacts using a lint-free cloth and some isopropyl alcohol. Be careful not to damage any sensitive components.
• Inspect the cartridge sensor area inside the printer for any dust or toner buildup. Use a soft brush or compressed air to clean out any debris around the sensor area.
• Reinstall the toner cartridge and close the printer.

3. Try a Different Toner Cartridge

• If cleaning and reseating the toner cartridge doesn’t resolve the issue, there may be a problem with the toner cartridge itself.
• If you have a spare toner cartridge or another compatible cartridge available, swap it out and see if the error persists.
• If the printer works with a different toner cartridge, then the original cartridge may need to be replaced.

4. Perform a Printer Reset

• Sometimes, performing a reset on the printer can clear sensor or communication errors.

1. Turn off the printer.
2. Unplug the power cable from the printer and wait for 1-2 minutes.
3. Plug the printer back in and power it on.
4. Check if the error code persists.

5. Check for Firmware Updates

• Ensure your printer’s firmware is up to date. Outdated firmware can sometimes cause issues with toner detection.
• Go to the HP Support website and search for the latest firmware for your HP LaserJet MFP E78223 model.
• Follow the instructions on the site to download and update the printer’s firmware.

I hope this helps.

Take care and have a good day.
