Quick Reference for Indicator Lights:
Indicator Light Warnings
The POWER indicator light does not light
The printer is receiving no power. If you are using the AC adapter, make sure it is connected
properly. Make sure the AC power outlet is "live." If you are using a DC adapter, make sure power
is connected and that the fuse is working correctly.
No Battery Found When Charging
If this indication occurs immediately when attempting to charge the battery, the printer did not
detect a battery when you tried to initiate a battery charging cycle. Make sure the battery has
been installed and connected properly and that there are no broken wires at the battery or con-
nector.
If the battery is connected properly, you may have attempted to charge the battery and it has
become overheated during the charge cycle. An internal thermal breaker will open when over-
heated, and after cooling, will close again. Allow the battery to cool before continuing to charge it.
If the problem occurs again, replace the battery.
