4.2.2 Print tHead Broken Element Check
This function is used to check for any broken thermal elements of the print head.
If blurred print or missing dots occurs, this check helps you find whether the thermal elements are actually
broken or the print head is just stained.
Also, use this check just after a replacement of a print head to find an initial failure.
