LED Behavior and States
 Steady Blue = Printer is on and Ready-to-Work.
 Flashing Blue: 50% duty cycle, 0.75 Hz = Printer
is on, but not ready to work or there is a critical
error.
 Off = Printer is off or in deep sleep mode.
 Flashes White: for 0.04 seconds for each packet
sent or received = Printer is communicating with
host (actively sending data)via USB, IrDA,
Bluetooth, or WiFi 802.11 radio.
 Off = No data is being sent or received.
Off Charger
 Off = Battery does not have a low charge.
 Flashing Red: 25% duty cycle, 1 Hz = The
battery has a low charge.
On Charger
 Steady Green = The printer is connected to
external power, and the battery is more than
95% charged.
 Pulsing Green: (The output to the LED should be
driven with a pulse width modulated (PWM)
signal. The frequency used should be above the
human perception of any flicker. The difference
between PWM duty cycle changes should be
small enough so that there is no discernable
jump in output brightness. The duty cycle should
linearly change for 1.35 seconds to maximum
brightness, linearly change for 1.35 seconds to
minimum brightness and then remain off for 0.80
seconds. The resulting period of 3.50 seconds is
for a complete cycle from off to maximum
brightness and back to the off condition.) = The
printer is connected to external power and the
battery is charging and the battery is between
75% and 95% charged
 Steady Red = the printer is connected to external
power and the battery is charging, and the
battery is between 0% and 75% charged
 Flashing Amber at 50% duty cycle, 1 Hz = The
battery is out of charging temperature range.
 Flashing Red at 50% duty cycle, 1 Hz = There is
a battery error.
