Indicator Warnings

Head or motor is cooling down

The print head or motor is too hot.

Print head:
If the print head becomes too hot, it may produce imaging on the paper in areas not intended to be printed. This condition is normal when printing a large number of documents with a high print density.
The printer will stop, then 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 areas being printed (for example, remove background shading and colours in graphs and presentation documents). Also, make sure that the printer has adequate ventilation and is not located in an enclosed space.

Motor:
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.

• Is the Media Roll installed correctly?
  If not, remove the Media Roll, and then reinstall it.


• Are the media guides not touching the side of the Media Roll?

• If the error still occurs, check for the following:
  • Tape exceeding 39.37" (1 m) or incompatible files cannot be printed.
  • When sending a template as a BLF file, an error is indicated if the model name in the file is different.
  • When printing a template, an error is indicated if the specified template does not exist.
  • An error is indicated if the search of a template with a linked database fails.
  • An error is indicated if data is transferred, causing the capacity of the user storage area to be exceeded.

   

  In these cases, turn off the printer, and then turn it on again.

Error 2 has occurred.
 

• Has a device been connected that is not supported by the USB host port?
  An overcurrent was detected by the USB host port, or the connection of an unsupported device was detected. Turn off the printer, and then check the connected device.
  If a USB hub is connected, the printer will automatically turn off after a certain length of time has passed.


• Is the printer in mass storage mode?
  An error is indicated if the file system becomes corrupted or a file is copied while a mass storage file is being processed.
  Turn off the printer.
