Hi @Brian458,
Welcome to the HP Support Community.
Thank you for posting your query. I will be glad to help you.
I understand you have trouble using the HP OfficeJet Pro 8600, getting a cartridge damage error and not able to use it. Sorry to hear about the issue. Please try the steps shared below.
Step 1: Clean the cartridge's electrical contacts
Remove any debris or buildup from the contacts on the cartridges.
1. Open the door or lid to the cartridge access area. Wait until the carriage stops moving before continuing.
2. Push in on the cartridge indicated in the error message to release it from the carriage.
3. Wipe the copper-colored contact on the cartridge with a lint-free cloth. If the copper-colored contact on the cartridge is missing or damaged, the cartridge must be replaced.
4. Slide the cartridge into its colour-coded slot until it clicks into place.
5. Repeat these steps for any other cartridges indicated in the error message.
6. Close the door or lid to the cartridge access area.
