Printer in error after installing new ink cartridge

[JeannieAS]

I have ab HP 8600 printer. I just replaced one of the ink cartridges and now I get an error message. I did the turn off and back on routine, and the unplug and replug routine. Still get the error message and no home screen. Help. ( iknow it is an older printer but have not had any issues before now)

@JeannieAS, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Remove & Reseat All Ink Cartridges

Even if only one cartridge was replaced:

Power off the printer.

Open the cartridge access door.

Remove all cartridges (not just the new one).

Inspect contacts (copper/gold contacts on the cartridge and inside the printer).

Gently clean the contacts with a lint-free cloth and a bit of distilled water or isopropyl alcohol.

Reseat all cartridges firmly — a loose cartridge can trigger errors.

Run HP Smart:

• Download and run the HP Smart. Follow the prompts to diagnose and fix common printing issues.
• Refer: Use Diagnose & Fix in HP Smart to repair common printing issues (Windows, macOS) | HP® Support

Update Printer Firmware (Update the firmware on an HP printer | HP® Support)

• Go to the HP Customer Support - Software and Driver Downloads page. Enter your printer model number and search for the latest firmware update. Follow the instructions to download and install the firmware update.

I hope this helps.
