Why the LED lamp on the machine flashing GREEN?


Description of Solution 200000041520

The following can cause the lamp to flash GREEN:

 

A. The printer is having problem feeding out the label, not detecting the black box on the right side of the backing tape.

 

Note: Brother DK labels/tape rolls have special markings for the printer to detect which labels/tape roll is loaded.  Using a non-Brother roll without the special markings will not work in the printer.

 

B. The DK label/tape roll “Size” in the printer does not match the “Size” selected in the software.

 

Note: The Size of the DK label/tape roll is listed on the left side of the spool.

 

C. There is a communication error between the PC and the label printer.

 

Please follow the steps below to isolate the problem.

 

1. See if there is an error message on the PC screen; it may give a clue to why the LED is flashing GREEN.

 

2. Turn the printer OFF and remove the DK label/tape roll from the printer compartment.  On the right side of the compartment, there are five sensors to detect which DK roll installed in the printer.  They are small black post about 1/8 inch high stick out from inside the printer.  Visually check if any sensor stuck in the down position or physically damaged.  Next push down on each of the sensor switches; they should spring back up and they all should be the same height.  If it does not spring back up, the sensor switch is bad; the machine require service.

 

 

3. Reinstalling the Brother DK label/tape roll.  Insert the spool of the DK Roll along the spool guide on the right side of the compartment (the DK roll needs to be against the right side of the compartment).  Ensure the strip of labels/tape is NOT trapped under the spool on the right (the bottom of the spool has to make direct contact with the five switches located on the right side of the compartment) and the DK roll is seated firmly in the compartment.  Rotate the roll on the spool towards the back of the machine, it should rotate freely.  Next, thread the end of the roll into the slot until the edge of the roll can be seen at the front of the printer, push down the release lever, and close the cover.

 

 

4. Press the FEED button, the LED should remain GREEN.  If a Die-cut label roll is installed in the printer, it is normal for the printer to feed the label/tape backward when the FEED button is pressed.  As long as the LED remains GREEN (not flashing), it is OK. 

 

If the LED flashing GREEN, turn OFF the printer and try reinstalling the DK label/tape roll again.

 

Ensure the labels/tape is NOT under the right foot of the spool (the foot has to make direct contact with the five switches located on the right side of the compartment).  The tab on the right side of the spool has to slide between the opening of the guides on the right side and the roll is seated firmly in the compartment.

 

Ensure the tape backing is facing up (contains the Brother logo and the black boxes) and the label/tape facing down, thread the end of the roll into the slot until the edge of the roll can be seen at the front of the printer.  If the end cannot be threaded through to the front of the printer, there could be a label jammed inside the printer.  Insert a business card from the DK roll compartment and try pushing the jam label out toward the front of the printer.

 

If the LED still flashing GREEN, after the FEED button is pressed, the machine requires service.

 

5. Go to the P-touch Editor software; ensure the label Size selected in the software matches the DK roll Size in the printer, both visually and by clicking on the Check Media button/icon and then try printing a test label.

                      

 

 

6. If the LED flashing GREEN or “Communication error” message appears when attempting to print a label:

 

A. Ensure the label Size selected in the software matches the DK roll Size in the printer and that the USB cable is connected at both ends.

 

B. If the USB cable connected to a hub, try connecting the USB cable directly to the PC.

 

C. Try connecting the USB cable to another USB port of the PC.

 

D. Try another USB cable.

 

E. Try un-install and re-installing the driver.  If possible, try connecting the printer to another PC.

 

If the problem persists, your machine may require service.
