the left slightly to engage the threaded parts of the screw and 
the hole correctly, then tighten it.
 Make sure to follow the specified tightening torque.
 When securing the Printhead, make sure to observe strictly the

in advance, and attach it to the new one without any gap confirming 
the correct direction to avoid installing it to the wrong holes.
