3.4 Label Calibration and Self Test
Label Calibration
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.
Self Test
Self-test function lets you check whether the printer is functioning normally.
Here is how you run the label size calibration and self test.
1. Check that the label stock is loaded correctly.
2. Turn off the printer.
3. Turn 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.
4. Once the printer has successfully measured the label stock, it will print a self-test label.
The contents of a self-test printout are listed below.

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.

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
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
ion 5-6.)
Sect
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
tension of the ribbon

used to clean the print head.
5.4 Cleaning the thermal print head
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
