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, you need to run the auto-detection func
tion on the label stock (see
Section 3-5).
PAUSE button
Pressing the PAUSE button while the printer is in standby mode will set the printer to pause mode. In this mode, the printer can receive commands, but it can only process them when it is reset to standby mode. Pressing the PAUSE button again will reset the printer to standby mode.
Pressing the PAUSE button during printing will interrupt printing. When the PAUSE button is pressed aga
in, the printer resumes printing. Example: While a 10-label print job is running, you press the PAUSE button to pause the printer. Two of the labels have been printed. To resume printing and print the remaining eight labels, you press the PAUSE button again.
CANCEL button
Pressing the CANCEL button during printing cancels a print job. The current print job is cancelled. Example: While a 10-label print job is running, you press the CANCEL button. Two of the labels have been printed. The print job is cancelled and the remaining eight labels are not printed.
You can combine the FEED, PAUSE and CANCEL buttons in a number of ways to perform different pri

3.5 Dump mode
If the label settings do not match the printer output, you can switch the printer to dump mode to check whether an error has occurred during the transfer between printer and host computer. In dump mode, the unprocessed raw data are sent to the printer and printed. This shows you quickly whether any data are sent to the printer at all.
Here is how you switch to dump mode:
1. Switch off the printer.
2. Switch on the printer and keep the FEED button pressed.
3. You will hear 3 beeps first and then one beep later. Release the FEED button after the last beep. The printer will automatically print "Dump Mode Begin". That means the printer is now in dump mode.
4. Send commands to the printer and check whether they match the printer output.
To exit dump mode, press the FEED button. The printer will automatically print "Out Of Dump Mode" and switch to standby mode. Alternatively, you can switch off the printer to exit dump mode.

3. TPH print line adjustment:
When printing is slow or
when printing on thick label stock, the print line must be moved to the front (in paper feed direction) for a better print result. Using a flat-head screwdriver, turn the screws clockwise to move the TPH forward.
The two screws on the left
and right must be adjusted to the same position to ensure the print line and feed roller are in parallel.
One turn of the scre
w
moves the print head by 0.5
mm. To keep track of the change in quality, you should adjust the screws by ¼ turn at a time.
If no improvement is visible,
gently turn the screws clockwise as far as possible, then restart the adjustment
process from there.

5.3 Adjusting the print line
You can adjust the ribbon tension by
turning the ribbon shaft knob (green wheel at the base of the ribbon supply hub – see illustration) clockwise or anticlockwise. There are 4 possible settings, which are marked on the knob of the ribbon rewind hub and the ribbon supply hub. When set to 1, the tension is highest, while the tension is lowest at 4. If the tension is so low that the ribbon does not move forward, you need to reduce the
tension of the ribbon supply hub or increase the tension of the ribbon rewind hub. To set the tension, press in the knob and turn it clockwise or anticlockwise as required.
Increasing the tension of the ribbon rewind hub will remove any wrinkling of the ribbon during printing, which results from the use of different ribbon materials. (For details about the wrinkling/creasing of ribbons, see Sect
ion 5-6.)
If you are using a very narrow ribbon, the printer may not move the label stock forward (particularly with a ribbon that is less than 2" wide). In that case, reduce the tension by turning the knob of the ribbon supply hub anticlockwise. If the tension is too high, the ribbon core may be crushed and thus impossible to remove. In that case, reduce the tension of the ribbon supply hub and the ribbon rewind hub by turning the
knobs anticlockwise.

5.4 Cleaning the thermal print head
Dirt on the print head or ribbon
may result in inadequate print quality (no printed image on part of the label). The printer cover should therefore be kept closed whenever possible. Keeping dirt and dust away from the paper or labels ensures a good print quality and a longer lifespan of the print head. Here is how you clean the print head:
1. Switch off the printer.
2. Open the printer cover.
3. Remove the ribbon.
4. Release the
print head by turning the print head release lever.
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 1】
The print head should be cleaned once a week.
Note 2】
Please make sure that there are no metal fragments or other hard particles on the soft cloth
used to clean the print head.

5 Maintenance and Adjustment
5.5 Adjusting the balance and print head tension
1. Open the printer side cover.
2. Pull out the print head
release lever as shown in the illustration (1) and turn it anticlockwise to a top right position (2).
When using a variety of label
stock and ribbons, the ink may not be evenly distributed. If there is no printed image on one side of the paper, or the ribbon wrinkles, the print head pressure must be readjusted using the TPH spring boxes.
3. Move the TPH spring boxes as shown in the illustration to change the print head pressure. The wider the medium you are using, the further out the TPH spring boxes must be moved.
If there
is no quality improvement, you need to change the pressure on the TPH
spring boxes.
4. Turning the screw clockwise
increases the pressure, while turning it anticlockwise reduces the pressure.

5.6 Ribbon shield settings
1. The use of different ribbon materials may cause wrinkling of the ribbon, which in
turn affects the print result as illustrated by the examples in (a) and (b). To change the print quality, you can adjust the ribbon shield screws.
If your print result looks like the example in (a), you need to turn ribbon shield screw A clockwise. If your print result looks like the example in (b), you need to turn ribbon shield
screw B clockwise.
(a) (b)
2. To keep track of the change in print quality, you should adjust the screws by half a
turn at a time. Print a test page. If there is no improvement in the print result, turn the screw by another half turn. Do not turn the adjustment screw more than two full turns.
Note】
If you adjust the screw by more than two full turns, the paper feed may no longer function correctly. In that case, unscrew the ribbon shield screws fully and restart the
adjustment process.

adjusting the cutter are located on both sides of the cutter.
2. In the event of a paper jam,
the cutter will no longer function correctly. Switch off the printer and use a hex key (#M3) to turn the socket head screw.
3. Turn the key anticlockwise
to remove the jammed paper.
4. When you have removed
the jammed paper, you can switch the printer back on. The cutter will automatically reset.
