 Liquid (electrolyte) leaking from the printer or rechargeable battery may indicate that the 
rechargeable battery is damaged. If the rechargeable battery leaks, immediately stop using the 
printer, unplug the AC adapter, and isolate the printer by placing it in a bag.
DO NOT touch the electrolyte. If electrolyte gets in the eyes, do not rub them. Immediately rinse 
liberally with tap water or other clean water and seek the advice of a medical professional. If left 
alone, the electrolyte could cause eye damage. If electrolyte contacts your skin or clothing, 
immediately rinse them with water.
 DO NOT put the rechargeable battery, or a printer with the rechargeable battery installed, into 
a microwave oven or a high pressure container.
 DO NOT disassemble, modify, or attempt to repair the rechargeable battery.
 DO NOT dispose of the rechargeable battery in fire or intentionally overheat. This could cause 
the internal insulation to melt, gas to be emitted, or safety mechanisms to fail. Additionally, the 
electrolyte solution could catch fire.
 DO NOT puncture the rechargeable battery with any objects, subject it to severe shocks or 
throw it. Damage to the rechargeable battery’s protection circuit could cause the rechargeable 
battery to be recharged at an abnormal current/voltage or cause an abnormal chemical reaction 
within the rechargeable battery.
 DO NOT leave a drained rechargeable battery in the printer for a long period of time. This could 
shorten the life of the rechargeable battery or lead to an electrical short.
 DO NOT incinerate the rechargeable battery or dispose of it with household waste.
If the printer can only be used for a short period of time, even though the rechargeable battery is 
fully charged, the rechargeable battery may have reached the end of its service life. Replace the 
rechargeable battery with a new one. When removing and replacing the rechargeable battery, cover 
the terminals of the old rechargeable battery with tape to avoid creating a short in the battery.
