Cartridge Error E0

[Jools76]

I recently changed the black cartridge in my printer with the one sent by HP instant ink and since then an error is coming up for the colour cartridge? I've followed the support on the website - turned it off at the power cord, reset the printer etc and still no joy! It is now not always connecting to the internet? I've only had it 6 months! Help!

Hi @Jools76 ,

Welcome to HP Support Community.  

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

It seems like you've already taken some troubleshooting steps, but let's try a few more to see if we can resolve the issue with your HP DeskJet 2722e All-In-One Printer:

Restart the Printer:

• Turn off the printer using the power button.
• Unplug the power cord from the back of the printer.
• Wait for about 60 seconds.
• Plug the power cord back into the printer.
• Turn on the printer.

Check Cartridge Installation:

• Ensure that the cartridges are properly installed. Open the printer cover and make sure both the black and color cartridges are securely in place.

Reinstall Cartridges:

• Remove both the black and color cartridges.
• Turn off the printer and unplug the power cord.
• Wait for a few minutes.
• Plug the power cord back in and turn on the printer.
• Reinstall the cartridges and check if the error persists.

Update Firmware:

• Check if there is a firmware update available for your printer on the HP support website. If so, update the firmware as instructed.

Check Internet Connection:

• For the connectivity issue, ensure that your printer is within range of your Wi-Fi network.
• Check if other devices can connect to the same Wi-Fi network without issues.
• If necessary, restart your router and reconnect your printer to the Wi-Fi network.

Reset the Network Settings:

• On the printer control panel, navigate to the Setup or Network menu.
• Find the option to reset network settings and follow the on-screen instructions to reset the network configuration.

I hope this helps. 

Take care and have a good day.
