    i have same problem, pull out the ink cardridges and shut machine, then turn off and on. See if it clears. Mind did after trying just about everything else. I think it happed shortly after i put in a "recycled" ink into my machine. I ordered an OEM new cartridge, hope that fixes. At least i have it isolated to the ink.

Perform a partial reset of the HP All-in-One

  1. Turn on the HP All-in-One.
  2. Disconnect the power cord from the back of the unit.
  3. Press and hold the # and 3 buttons simultaneously.
  4. While still holding down the # and 3 buttons, connect the power cord to the back of the unit.
  5. Continue holding the buttons until the Power button blinks.
