Error code o

[oldtimer78]

Hello all!

Would appreciate your help. I own a HP Deskjet 2800e All-in-One Printer. The problem began upon changing the ink cartridges. No problem prior to that!  The printer is only a few months old, so it was the first time I have changed them in this machine.

A sign appears: error o.  The cartridges are new and are HP's 305.

I've checked them several times for dirt, etc-all is fine. And they are seated fine. 

This has put me off wi-fi printers! I have checked lots of online advice-much of it the same-check this, check that, etc but to no avail. I would appreciate any advice to rectify this problem., which frankly is driving me nuts.

Thanks in advance.

Try these steps:

Check Cartridge Compatibility:

• Ensure that you are using the correct HP ink cartridges for your printer model. For the HP DeskJet 2800e, it should be HP 305 ink cartridges.

Reinstall the Ink Cartridges:

• Turn on the printer.
• Open the ink cartridge access door.
• Remove the ink cartridges from the printer.
• Inspect the cartridges and the contacts inside the printer for any debris or damage.
• Reinsert the cartridges carefully, ensuring they are properly seated.

Clean the Ink Cartridge Contacts:

• Turn off the printer.
• Remove the ink cartridges.
• Using a lint-free cloth or cotton swab lightly moistened with distilled water, gently clean the electrical contacts on the ink cartridges and inside the printer.
• Allow the contacts to dry completely before reinstalling the cartridges.

Reset the Printer:

• Turn off the printer and unplug it from the power source.
• Wait for about 60 seconds.
• Plug the printer back in and turn it on.

Check Printer Firmware:

• Ensure that the printer firmware is up to date:
  • Visit the HP Support page for DeskJet 2800e.
  • Enter your printer model and download any available firmware updates.
