My HP Envy 744 is stuck in single cartridge mode,

I subscribe to HP Instant INK program, and just installed two new cartridges.  Now the printer will only print in single cartridge mode, and the supplies window indicates the tri-color cartridge is empty.  My printer is up to date.  How to get the printer to engage the new tri-color cartridge and switch into dual cartridge mode?

Welcome to the HP support community.

 

Clean the ink cartridge and carriage electrical contacts

Remove any debris or buildup from the contacts on the cartridges and in the carriage.

  1. Open the door or lid to the cartridge access area. Wait until the carriage stops moving before continuing.

  2. Remove the cartridge indicated in the error message from the carriage.

    • Carriages with cartridge latches: Open the latch, and then pull the cartridge up and out of the slot.

    • Carriages without cartridge latches: Gently press down on the cartridge to release it, and then pull it out of the slot.

  3. Holding the cartridge by the sides, remove any protective tape that still might be on the contacts.

    CAUTION: 

    Do not touch the ink nozzles or the copper-colored electrical strip. Touching or trying to remove these parts can result in clogs, ink failure, and bad electrical connections.

  4. Lightly dampen a lint-free cloth with distilled water, and then wipe the copper-colored contacts on the cartridge.

  6. Wait 10 minutes for the contacts to dry, and then reinsert the cartridge into its color-coded slot.

  7. Repeat these steps for the other cartridge if it was indicated in the error message.

  8. Close the door or lid to the cartridge access area.

    If the error persists, clean the cartridge and carriage contacts a second time.
