When printing, blue heading went pink. We have tried to: Change black cartridge that was nearly empty, we have adjusted the printer head, we have cleaned the printer head, we have tried gently to add moisture til the nozzle, we have deleted and reloaded the APP. After this we also tested with av picture. It turned out to be pink. Any suggestions?

Welcome to the HP support community.

 

Make sure the ink cartridges are properly vented and seated correctly

  1. Turn on the printer, if it is not already turned on.

  2. Open the ink cartridge access door.

    The carriage moves to the center of the printer.

    Open the cartridge access door

  3. Wait until the carriage stops moving before you continue.

  4. Press the tab inward on the front of the old ink cartridge to release it, and then pull up on the ink cartridge to remove it from the slot.

  5. Examine the vent area above the HP logo on the top of the ink cartridge.

  6. If the ink cartridge still has the orange pull-tab attached, pull to remove it.

  7. If the vent is clogged, use a straight pin to gently remove excess adhesive from the vent.

  8. Turn the ink cartridge so that the ink cartridge contacts face downward, and then match the label color with the color dot on the carriage.

  9. Slide the ink cartridge into its slot, and then gently press the ink cartridge down until it snaps into place.

  10. Repeat these steps to inspect the vents on each of the ink cartridges.

  11. Make sure each ink cartridge is firmly installed in its slot. Run your finger along the top of the ink cartridges to feel for any that are protruding, and if any are, press down firmly until each ink cartridge snaps into place.

  12. Close the ink cartridge access door.
