The POWER indicator does not light
The printer is receiving no power.
If you are using AC or DC power, make sure that the AC adapter or Car adapter is properly connected and make sure that the AC or DC power outlet is turned on.
If you are using DC power, check the fuse.
Head or motor is cooling down
The thermal head or motor is too hot.
If the thermal head becomes even hotter, the thermal head may produce imaging on the paper in areas not intended to be printed. This condition is normal when printing documents with a great deal of “black” content.
The printer will stop and resume printing after the print head has cooled down.
To avoid or delay the onset of this condition, print using a lighter density setting, reduce the amount of black space being printed
(for example, remove background shading and colors in graphs and presentation documents), and make sure that the printer has adequate ventilation and is not located in an enclosed space.
Do not use the printer continuously. If the printer is used continuously, the motor will become too hot. In this case, the printer will stop and resume printing after the motor has cooled down.
This condition may occur more often when the printer is used at high altitude (more than 10,000 feet) due to a lower air density available to cool the printer.
Data reception error
Data may not be received correctly when communications are unstable.Try connecting again when communication conditions have improved.
Printer is in boot mode
The AC adapter was unplugged while the firmware was being updated, and the printer started up in boot mode the next time it was started.
