Epson TM-U375 Printer User Manual


 
If there is no paper jam and the printer has been printing for quite a while,
the print head may be overheated. If the print head is overheated, the
printer will resume printing when the head has cooled (usually within two
or three minutes).
If there is no paper jam and the print head is not overheated, turn off the
printer and turn it back on after about 10 seconds. If the printer still does
not work, unplug the power supply cord from the outlet immediately. Then
contact a qualified service person.
The ERROR light is off but nothing is printed.
Try to run the self-test to make sure that the printer works properly. See
Self-test later in this section. If the self-test does not work, contact your
dealer for assistance.
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. 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
the computer. Make sure that the printer’s DIP switch settings for data
transmission are the same as the
computer's.
You can print the printer’s
interface settings using the self-test. See
Running the
Self-test
in Chapter 1.
If the printer still does not print, contact your dealer for assistance.
The printer sounds like it is printing, but nothing is printed.
