You can charge the built-in
battery by connecting the included micro USB cable to a computer or
any compatible USB power source, including some automobiles.
For USB charging, the printer must be turned off or in
sleep mode.
To charge from a computer,
make sure the computer is on and not in sleep or hibernation
mode.
Connect the micro USB
cable to the printer's micro USB port and to any USB port on the
computer.
Note: You
cannot charge the battery using a USB hub; connect the product
directly to the computer. If battery charging does not start,
select Menu > Battery > Battery Settings > USB Power Supply via PC > On on the control panel and try again.
The battery charging light turns
on.
During charging, the computer
recognizes the printer as a USB mass storage device.
