Safety Precautions
All safety procedures described here shall be strictly adhered to by all parties servicing and maintaining this 
product.
DANGER
Strictly observe the following cautions. Failure to comply could result in serious bodily injury or loss of life.
1. Always disconnect the product from the power source and peripheral devices when servicing the product or 
performing maintenance.
2. When performing works described in this manual, do not connect to a power source until instructed to do so. 
Connecting to a power source causes high voltage in the power supply unit and some electronic components 
even if the product power switch is off. If you need to perform the work with the power cable connected to a 
power source, use extreme caution to avoid electrical shock.
WARNING
Strictly observe the following cautions. Failure to comply may lead to personal injury or loss of life.
1. Always wear protective goggles for disassembly and reassembly to protect your eyes from ink in working. If 
any ink gets in your eyes, wash your eyes with clean water and consult a doctor immediately.
2. When using compressed air products; such as air duster, for cleaning during repair and maintenance, the use 
of such products containing flammable gas is prohibited.
