Indicator Warnings

 

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 DC cable is properly connected (See the FAQ: "How to connect to an AC power outlet (Optional)" or "How to connect to a DC power outlet (Optional)".) and make sure that the AC or DC power outlet is turned on. If you are using a rechargeable battery, make sure that the rechargeable battery is firmly installed in the printer and is fully charged. If you are using DC power, check the fuse.

 

Error when beginning charging/discharging (rechargeable Ni-MH battery not installed)

The printer did not detect a rechargeable Ni-MH battery when you tried to charge the battery.
Make sure that the rechargeable Ni-MH battery is installed properly and that there are no broken wires at the battery or connector. (See the FAQ: "How to install the Ni-MH Battery (Optional)".)

If the rechargeable Ni-MH battery is connected properly, the battery may have overheated while charging. Allow the rechargeable Ni-MH battery to cool before charging it again. If this is a reoccurring problem, replace the rechargeable Ni-MH battery.

 

Charging/discharging timeout error (rechargeable Ni-MH battery)

The rechargeable Ni-MH battery is taking too long to charge (normally the battery should be fully-charged within 120 minutes). Replace the rechargeable Ni-MH battery.

 

Received data in buffer

Print data is saved in the buffer. Since printing will not begin until all data has been received, accidentally stopping the wireless LAN connection during transmission will save the data, leaving the printer in a state where it cannot print. Turn off the printer, and then turn it on again.

 

Head or motor is cooling down

The thermal head or motor is too hot.

Head:
If the thermal head becomes too hot, the thermal head may produce imaging on the paper in areas not intended to be printed. This phenomenon may occur when printing a large number of documents with a great deal of text and a high print density.
To avoid this, 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.

Motor:
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 / 3,048 m) due to a lower air density available to cool the printer.

 

Data reception error

With unstable communication, it may not be possible to receive data correctly. Improve the communication conditions, and then establish the connection again.

 

Printer is in boot mode
