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.
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.
Size of the DK label/tape roll is listed on the left side of the
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
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
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
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
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. 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
E. Try un-install
and re-installing the driver. If possible, try connecting the printer to
If the problem
