One of your ink sticks is not advancing. The .44 indicates the color.44 indicates it is not seeing the magenta stick moving down.
A stick is cracked or otherwise stuck and not advancing downward into the loader. If you put an ink stick in from a different model number printer it will have a different shape and not hit the switch in the ink loader.
If you have to slide sticks out, use a screw, like a dry wall screw and twist it into the ink block and slide it back andout.
