Printing in single cartridge mode says no toner

[twomutts]

I recently replaced my black ink cartridge and went to single cartridge mode.  Now I get an error saying that I am out of toner and nothing will print.

Hi @twomutts

Welcome to HP Support Community. This is a great place to post questions and find answers.
Thank you for posting your query. I will be glad to help you.

I see that you are facing cartridge issues with your HP All-In-One Printer.

Please follow the steps listed below to clean the electrical contacts of the cartridges:
1. Turn the printer on.
2. Open the door to access the cartridges.
3. Wait until the carriage stops moving before you continue.
4. Remove the cartridge indicated in the error message from its slot, holding it by its side.
CAUTION: Do not touch the copper-colored contacts or the ink nozzles. Touching these parts can result in clogs, ink failure, and bad electrical connections.
5. Remove any protective tape that still might be on the contacts.
CAUTION: Do not touch or try to remove the copper electrical strip.
6. Lightly dampen a lint-free cloth with distilled water, and then clean only the copper-colored contacts on the cartridge.
7. Lightly dampen a lint-free cloth with distilled water and then clean the electrical contacts in the carriage, located inside the printer.
8. Wait 10 minutes for the contacts to dry.
9. Reinsert the cartridge.
10. Close the cartridge access door.

Let me know if you are using instant ink cartridges.

Take care and have a great day ahead.
