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 colors 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.

Error 1 has occurred.

• Is the correct RD/Media Roll installed?
  Check that the correct media, for example, type (die-cut label or continuous length tape) and die-cut label size, is installed.


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


• Are the media guides not touching the side of the RD/Media Roll?
  Move the media guides against the side of the RD/Media Roll.


• Is there enough of the roll remaining?
  If not, install a new RD/Media Roll.


• Is the RD/Media Roll compartment top cover open?
  Check that the RD/Media Roll compartment top cover is closed.


• After the specified length of time (120 seconds) has passed, either the access point could not be found or two or more access points were found. Otherwise, the received packet is incorrect (when using the optional WLAN interface).
  * TD-2120N/2130N only


• 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.


• Does the rechargeable battery have a low charge? (when using the optional rechargeable Li-ion battery).
  * TD-2120N/2130N only
  Use the AC adapter.


• Has the rechargeable battery failed to recharge? (when using the optional rechargeable Li-ion battery).
  * TD-2120N/2130N only
  If the battery has not been recharged after a certain length of time, recharging has failed. Use the AC adapter.


• Has the wireless LAN or Bluetooth connection been interrupted? (when using the optional WLAN or Bluetooth interfaces).
  * TD-2120N/2130N only
  The wireless LAN or Bluetooth connection established while the printer is on was interrupted. Turn off the printer, check that the slide switch for the WLAN interface or Bluetooth interface has been turned on, and then turn the printer on again.

A system error has occurred.

If this condition occurs, turn off the printer, and then contact your reseller or Brother Customer Service.

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.
This issue must be resolved. Contact your reseller or Brother Customer Service for assistance.
