WA R „ Since the power switch is mounted on the secondary circuit of the power supply circuit, unless otherwise specified, always turn off the printer using the power switch. After all moving parts have stopped, wait several seconds and then disconnect the power cable from the AC plug socket to prevent electric shock or circuit damage during service operations.

„The cover open sensor for detecting the open/close condition of the front cover has an interlock switch that functions as a safety device. Therefore, it is prohibited to turn off this switch.

„A lithium battery is installed on the MAIN Board of this printer. Be sure to observe the following instructions when servicing the battery:

„Keep the battery away from any metal or other batteries so that electrodes of the opposite polarity do not come in contact with each other.

„Do not heat the battery or put it near fire.

„Do not solder on any part of the battery. (Doing so may result in leakage of electrolyte from the battery, burning or explosion. The leakage may affect other devices close to the battery.)

„Do not charge the battery. (An explosion may be generated inside the battery, and cause burning or explosion.)

„Do not dismantle the battery. (The gas inside the battery may hurt your throat. Leakage, burning or explosion may also be resulted.)

„Do not install the battery in the wrong direction. (This may cause burning or explosion.)

„Be careful not to let ink get into your eyes or your skin. If ink gets in your eye, flush the eye with water, and see a doctor if you feel discomfort in your eye.
