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

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 label stock is loaded correctly.

STEP-02Switch off the printer.

STEP-03Switch the printer on again, keeping the FEED button pressed. When the READY LED starts to flash

red and the STATUS LED lights up orange, 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.

6 Maintenance And Adjustment

6-1

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.



The print head should be cleaned once a week.



NOTICE

Please make sure that there are no metal fragments or other hard particles on the soft cloth

used to clean the print head.

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.

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
