First thing to try is to remove the power brick (not just the cord the whole brick) from printer for a minute then re insert and try it again. If this doesn't help try uninstalling it then re installing the printer

If the Nozzle Check Pattern page prints correctly and completely, the problem may lie within your software settings, the interface cable, or your computer.
