Are you getting a nozzle check at least?

Error code 00010030 signifies that there is some failure with the Multi Sensor. The Multi Sensor is located on the Printhead Carriage, and consists of a blue light, and the sensor itself. If you look at the Printhead Carriage, you'll notice a graphic of a pair of scissors on the side. Right below that is where the sensor is located. Dust, debris, and excess ink may have accumulated over the sensor, causing it to give a false error code. Clean it, and if that doesn't work, replace the sensor.
