3. Operation Panel
3-1 LED Operation Panel
FEED Button
When you press the FEED button, the printer moves the label to the defined stop position. If you are using
continuous labels, pressing the FEED button will move label stock until you release the button again. If you are
using individual labels, pressing the FEED button will move only one label. If the label does not stop at the correct
position, please run the auto calibration (See Section 3-2. for the label size calibration function) on the label stock.
LED Indicators
The printer is ready for operation
The printer has detected an error.
(See Section 3-2. for Error alerts)

3-2 Error Alerts
In the event of a problem that prevents normal functioning of the printer, you will see an error message on LED
indicators and hear some beep signals. Please refer to below table for the error alerts.
Error Indicators
Please execute Auto Sensing again.
Replace the paper or ribbon.
Possible reasons: the print medium
has become trapped around the
rubber roll; the sensor cannot detect
a gap or black mark between the
labels; there is no paper. Please reset
the sensor.
No ribbon is installed and
the printer is set to
direct thermal printing
mode.
1. To work in thermal transfer mode,
load a ribbon.
2. Alternatively, select the direct
thermal printing mode.。
First 2 beeps,
than 3 beeps
The memory is full. The
printer prints the message
"File System full".
Delete unnecessary data from memory.
Unable to find file. The
printer prints the message
"File Name Not found".
Use the "~X4" command to print all
files. Then check whether the files
exist and whether the names are
correct.
A file of the same name
already exists. The printer
prints the message "
Filename is repeated”".
Change the name of the file and try
storing it again.
High temperature at the
print head.
Wenn the printer is overheated, The
printer will stop printing automatically.
Once the print head has cooled down,
the printer switches to standby mode.
The LED indicator stops flashing.
The printing head is not
correctly closed.
Open the print mechanism and close
it again.

3-3 Label size calibration and Self Test Page
The printer can automatically detect and store label height.
That means the host computer does not need to transmit the label height to the printer.
And the self-test function lets you check whether the printer is functioning normally.
Here is how you run the label size calibration and self test.
STEP-01 Check that the paper is loaded correctly.
STEP-02 Switch off the printer and press Feed button.
STEP-03 Switch the printer on again, keeping the FEED button pressed. When the LED starts to flash red, release
the FEED button. The printer will now measure the label stock and store the label height.
STEP-04 Once the printer has successfully measured the label stock, it will print a self-test label.
Contents of a self-test printout are listed below.
(The data below is for reference only, actual result may vary according to each situation.)

3-4 Operation Panel
STEP 1, Let the printer enter Dump Mode
(For Desktop printer EZ100/EZ300/EZ500 series)
1. Power off the printer, press and hold the FEED key.
2. Power on the printer (while still holding the FEED key).
3. There are 3 serial short beeps first, then, 3 single beep.
Release FEED key when heard the 3rd beep.
STEP 2. Make sure Printer ready for print a label
STEP 3. Send a label or commands which met problem to the printer
STEP 4. Printer will print out a label with letters and numbers, please
take a picture on them and send us by email.
To cancel (get out of) the Dump Mode, please press the FEED key, and then the printer will
automatically print “OUT OF DUMP MODE.” This indicates that the printer is back to the standby mode.

4. Maintenance And Adjustment
4-1 Cleaning The Print Head
Dirt on the print head or ribbon, or glue residue from the label stock may result in inadequate print quality. The printer
cover must therefore always be closed during printing. Keeping dirt and dust away from the paper or labels ensures a
good print quality and a longer lifespan of the print head.
Cleaning Steps
Here is how you clean the print head.
1. Switch off the printer.
2. Open the printer cover.
3. Release the printing mechanism and lift it.
4. Remove the ribbon.
5. To remove any label residue or other dirt from the print head (see blue arrow), please use a soft
lint-free cloth dipped in alcohol.
NOTE
* The print head should be cleaned once a week.
* Please make sure that there are no metal fragments or other hard particles on the soft cloth
used to clean the print head.

4.2 Adjusting The Print Head Pressure
When printing on special media (with varying material thickness), the print quality may suffer. You will then need to
adjust the print head pressure.
Adjustment Steps
1. Open the printer cover.
2. Remove the ribbon.
3. Use a screw driver and slowly turn the adjustment screws for the print head to increase or reduce the print
head pressure. Do not screw it hard, otherwise the machine will be broken.
4. Turn the adjustment screws according to actual position which is unsuccessful printed. Turn towards +(Plus)
indicates : The pressure is increased;Turn towards –(Minus) indicates : The pressure is reduced.
Turn the adjustment screws
Screw for adjusting the print head pressure
Screw for adjusting the print head

4-3 Adjusting The Print Line
When the print line is incorrectly set, the print quality on one side of the medium may suffer.
In such a case, the print line must be adjusted so it is positioned parallel to the paper feed roller.
Adjustment Methods
1. To move the print head in direction A as indicated by the blue arrow, turn the adjustment wheel
anticlockwise (see arrow 1).
2. To move the print head in direction B as indicated by the blue arrow, turn the adjustment wheel clockwise
(see arrow 2).
Turn the adjustment wheel

The printer is switched on but the display
does not light up.
Check the power supply.
One or both LEDs light up red and printing is
interrupted.
Check the software settings (driver settings) or
command codes.
Look for the error alert in the table in Section 3-3 Error
alerts .
Check whether the cutter is functioning normally and
whether it is cutting at all. (Only if a cutter is installed.)
The label stock passes through the printer but
no image is printed.
Please make sure that the label stock is loaded the right
way up and that it is suitable material.
Please make sure that the ribbon is loaded correctly.
The label stock jams during printing.
Clear the paper jam. Remove any label material left on
the thermal print head and clean the print head using a
soft lint-free cloth dipped in alcohol.
There is no printed image on part of the label
or the image is blurred.
Check the thermal print head for dust or other dirt (label
material or ribbon residue).
Check for errors in the application software.
Check the ribbon for wrinkles.
Check the power supply.
Run a self test (Section 3-2 ) and check the test print
pattern to see whether the print head prints over the
entire width of the medium.
Check the quality of the print medium.
The printed image is positioned incorrectly
or a label is missed out during printing.
Run the Label size calibration function. (Section 3-2)
Check the label height setting.
Check whether there is paper or dust covering the
sensor.
Check the paper guide settings.
The cutter does not cut off the labels in a
straight line.
Check whether the label stock is positioned straight.
The cutter does not cut off the labels
completely.
Check whether the label is more than 0.2 mm thick.
When using the cutter, the labels are not fed
through or cut off incorrectly.
Check whether the cutter has been correctly installed.
Check whether the paper guides are functioning
correctly.
The label dispenser is not functioning
normally.
Check whether there is dust on the label dispenser.
Check whether the label stock is positioned correctly.
