Ink cartridge is empty and I can not remove it to change it. It won't come out!

Press the power button to turn off the printer. Hold down the transfer and left arrow button at the same time. While holding them down at the same time turn on the power button. Let it go through the initialization process and once completed, the head should be in the up position. Open the cartridge door and push the cartridge to make sure it is latched and locked in place. Once the cartridge is latched, release the latch and the cartridge should release itself. Remove the cartridge from the printer.
