CAUTION!
1. Never touch the element when handling the print head.

3. Never remove the screws which secure the print head to the bracket. Doing so may cause
improper print quality.
4. Never disassemble the head block frame. Doing so may cause a print failure, such as ribbon
wrinkle, blurred print, etc.
5. When replacing parts or performing maintenance on the printer, be careful not to damage the
print head with a hard object like a watch or a ring.
Since the print head element can be easily damaged by shock, please treat it carefully by not hitting
a hard object against it.

head being hot.
