Cleaning The Print Head - Labau TM200 User Manual

※ If the PAPER "Red" light is blinking,
The paper roll is not installed or is at or near the end. Install a new
paper roll. See Chapter 1 for instructions.
※ The ERROR light is Off, but nothing is printed.
Try to run the self test to check that the printer works properly. See
the self test instructions in Chapter 1 to run the self test. If the self
test does not work, contact your dealer or a qualified service person.
If the self test works properly, check the following:
1. Check the connection at both ends of the interface cable
between the printer and the computer. Also make sure that this
cable meets the specifications for both the printer and the
computer.
2. The data transmission settings may be different between the
printer and computer. Make sure that the printer's DIP switch
settings for data transmission are the same as the computer.
You can print the printer's interface settings using the self test.
If the printer still does not print, contact your dealer or a qualified
service person.
※ Printing is poor.
Paper dust on the heating element of the thermal print head can
lower the print quality. Try cleaning the print head as described
