CAUTION: The battery LED may not illuminate if the battery is incorrectly inserted. If the LED fails to illuminate, quickly correct the battery direction. Quickly unplug the external power supply and battery pack if a battery charging error occurs. This could indicate that the battery pack is malfunctioning and should not be used. Note: I f the battery temperature is 0 єC or lower, or 40 єC or higher, the battery will not charge, even if the battery LED is illuminated. We recommend charging the battery at room temperature ( 10 є C ~ 30 єC). Make sure to recharge the battery pack if it has not been used for a week or longer.
The battery charging time varies depending on the battery level and other individual variables. 2.5.4 Using with a Battery Pack The battery LED indicates the battery level. Note: The battery level is only a general guide. Replace the battery as soon as possible once the battery level is displayed as L. If the battery level quickly returns to “Level L” even after recharging, the end of the battery life has been reached. Replace with a new battery. (Battery life: Approximately 500 charges) Never remove the battery pack or disconnect the external power supply while printing. The correct battery level will not be displayed if the battery pack temperature and ambient temperature differ.
If you require a relatively accurate battery level display, we recommend that you wait until the battery pack has cooled down after charging before use. The print density may vary depending on the user environment and battery level. 2.5.5 Providing power from the external power supply When you would like to drive the printer with the external power supply, read following section. 2-10 Setup Rev.
