A21 Home Error refers to the printhead not moving. Most cases, it is due to the fuse being blown on the main logic board. You have to remove the top cover. Open the clear cover, pop out the plastic pins, remove, then pull off the tractor knob on the right, remove the two screws at the top back of the printer, lift up the cover from the back towards the front. You will have to unplug an electrical connect ribbon from behind the control panel. Check the fuse and replace if necessary.
