Epson TM-T88II Series user manual Error light is off, but nothing is printed, Printing is poor

Page 28

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 ERROR light is still flashing, contact a qualified service person.

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 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 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.

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 below:
