    Safety Precautions Before you start using the equipment, read the [Safety Precautions] carefully and handle the equipment correctly so that the equipment can fully deliver its performance. This manual also contains safety precautions as shown below in order to prevent harm to people and damage to property.
  • Page 5 About the Power Supply Danger Handle the power cable with care. Do not scratch, modify, or heat the power cable. Do not put any heavy objects on the power cable. Failure to observe this may damage the power cable, thus leading to fire or electric shock.
  • Page 6 About the Printhead Warning Handle the nozzle face with care. The nozzle face (ink ejection face) is a delicate component. Pay special attention not to allow hands, objects, or target objects to come into contact with the nozzle face. Be aware that the printhead becomes very hot. The area around the printhead becomes hot when the power is on.
  • Page 7 Do not install this product in the following places, since this product is a precision device. Danger Do not install the equipment at a hot or humid place. Do not use this equipment at a place where the temperature is high (for example, due to direct exposure to sunlight) or at a place where the humidity is high.
  • Page 8 Caution Do not install the equipment at a place where there is not enough clearance around the equipment. Secure enough space around the equipment for maintenance work. Secure enough clearance in front of the printhead so that you can wipe the printhead face with the dedicated wiper, while looking at the nozzle face to minimize the vibration to the printhead.
