Charging and using the battery Fully recharge the battery before using. The battery is normally warm while it is charging. Do not charge it in a briefcase or other confined space as this may cause the battery to overheat. The AC adapter is normally warm to the touch when plugged into an AC outlet. 1 Install the battery. 2 Plug in the AC adapter and turn on the printer. The Battery charge LED is green while charging, and turns off when the battery is fully charged. After the battery is fully charged, you can use the printer without connecting to the AC power supply. Important notes Take note of the following when charging or using the battery: It takes approximately 1 hour and 30 minutes to charge. The Battery charge LED is green when the battery is charging. If it is red, the battery may be faulty and need to be replaced. The Power LED is green when the battery is 41-100% charged, amber when 10-40% charged, and red when less than 10% charged. Charge the battery when the Power LED turns amber. If it turns red, charge the battery as soon as possible. The battery status is also displayed on the Printer Status tab in the Toolbox. If your battery is running low, either plug in the AC adapter to charge, or replace the battery with one that is charged. A fully charged battery can last up to approximately 350 pages, depending on the complexity of print jobs. If the printer is left idle for 10 minutes, it will go into a low-power mode to conserve battery power. Prior to long-term storage, charge the battery fully. Do not leave the battery in a discharged (empty) state for more than 6 months. To maximize battery life and capacity, observe the following temperature guidelines: • Charging: 32° to 104°F (0° to 40°C) • Using and storing: -4° to 122°F (-20° to 50°C). 1-7 ENWW
