7 Using attention
7.1 Please notice, the ESD wrist ring and the humidity manufactures ETC, when using the
printer, to protect the inner electronic parts of the printer from the damage of ESD,
because the TPH of the Printer and photoelectric sensor are ESD Sensitive parts.
7.2 For protecting plastic shaft, don
’t smear any oil or others on the rubber parts.
