I had the same problem and just solved it.

How do I change the print cartridges?

  • Open the printer cover and prop it up with the support brace located on the right-hand side of the cover.
  • Remove the black FINE ink cartridge from its container and locate the protective tape. Gently remove the protective tape used to cover the print head nozzles and electrical contacts.
  • Insert the black FINE ink cartridge into the printer slot labeled "B." It will rest on a slight angle. Push the cartridge up and back until it clicks into place.
  • Repeat the process for the color FINE ink cartridge, placing it in the slot labeled "C."
  • Raise the printer cover slightly to loosen the support brace. Fold the brace inward and replace the cover to its closed position.
  • A green LED light will flash on top of the printer. In about a minute, the LED stops flashing and displays "1." Once the "1" appears, you're ready to print.

    Ink changing

    When the printer is, powered, turned on, and you open the cover; the print head is supposed to automatically reset itself to a position where you can change the ink.

    Dont know how to change colour cartridges

    Turn the printer on and open the lid. After a short while, the printer carriage unit containing the print head and ink cartridges will stop right in the middle of the printer, so you can easily replace the ink cartridges. After replacing them and ensuring they're fully seated, simply close the lid. The printer will run a few quick self-diagnostic checks and run a purge cycle, and it'll be good to go.

    Can't install the ink cartridge

    To get your cartridge installed, first turn your printer off. Open the lid like you normally do to change it. You can physically pull the cartridge carrier to the middle to change it. It will not hurt anything. Just be sure your printer is powered off. You see when it is on, the software keeps track of what character position the printer head is in. Like when you tried to stop it from printing it went to the left or home position because the printer software detected that it was not moving and printing in the right positions of whatever it was that you were printing. So good luck and God bless you. Once you power the printer back up after changing the cartridge everything will work and position itself just fine.

    It just wont work

    Move the ink cartridge carriage (the printhead) to the middle of the printer like you're going to change cartridges.  Take out all the ink cartridges.  There should be two black springs on either side of the printhead.  Remove these and the printhead should pop out.  Clean the nozzels (the little parts that squirt out ink) and reassemble.

    If this doesn't work, then you'll have to replace the printhead.

    Printer cartridge container doesn't stop in the middle

    It appears that the injection may have been lethal, it was still using the ink that it carries in its tubes then it mixed with the injection and is now blocked \ faulty. To repair it you could try getting a new set of HP inks.
