• Is the cable loose?
Check that the cable is connected securely.
• Is the RD Roll installed correctly?
If not, remove the RD Roll and reinstall it.
• Is the RD Roll used up?
Replace the RD Roll.
• Is the RD Roll compartment cover open?
Check that the RD Roll compartment cover is closed correctly.
• Has a print error or transmission error occurred?
Turn off the machine and switch on again. If the problem still
occurs, contact Brother Customer Service.
• Does the guide not touch the left side of the paper RD Roll?
Move the guide against the side of the RD Roll.
• Is the media on top of the gap sensor?
Feed the media under the gap sensor.
• Is the power cord plugged in correctly?
Check that the power cord is plugged in. If inserted, try plugging
it into another electrical outlet.
• Has the main power switch located on the back of the machine
been turned on?
Make sure the main power switch is turned on.
* If the power button still does not light up, contact Brother
Customer Service.
• Is the print head or roller dirty?
While the print head generally remains clean under normal use,
lint or dirt from the roller may become stuck on the printer head.
If this occurs, clean the roller.
See
"Roller maintenance" on page 28.
• Is the correct port chosen?
Check that the correct port is chosen from the "Print to the
following port" list in the Printer Properties dialog box.
• Is the machine in cooling mode (the LED lamp is flashing in
orange)?
Wait until the LED lamp stops flashing and then try printing
again.
• Is someone printing via network (TD-4100N only)?
If you try to print while other users are printing large amounts of
data, the printer is unable to accept your print job until the
ongoing printing is finished. In such situations, execute the print
job again after the other jobs are completed.
• Is there dirt or lint on the roller preventing it from rolling freely?
For details, please see
• Check that the ejection path of the label is not blocked.
• Check that the RD Roll is set correctly by removing the RD Roll
and reinstalling.
• Ensure that the RD Roll compartment cover is closed correctly.
• Is there dirt or lint on the roller preventing it from rolling freely?
