Troubleshooting

This chapter gives solutions to some of the more common printer
problems.

General problems

The lights on the control panel do not come on.

Make sure that the power supply cables are correctly plugged into
the printer, the power unit, and to the power outlet.

Make sure that power is supplied to the power outlet. If the outlet
is controlled by a switch or timer, use another outlet.

The

First, turn off the printer and check for a paper jam. (See the paper
jam description on page 3-3.)

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.

Troubleshooting 3-1

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’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.

The printer sounds like it is printing, but nothing is printed.

The ribbon cassette may not be installed properly. See the
instructions in Chapter 1.

The ribbon may be worn out. Replace the ribbon cassette as
described in Chapter 1.

The printout is faint.

The ribbon may be worn out. Replace the ribbon cassette as
described in Chapter 1.

3-2 Troubleshooting

A line of dots is missing in the printout.

The print head may be damaged. Stop printing and contact your
dealer or a qualified service person.

printer cover.

Hexadecimal Dump

This feature allows experienced users to see exactly what data is
coming to the printer. This can be useful in finding software
problems. When you turn on the hex dump function, the printer
prints all commands and other data in hexadecimal format along
with a guide section to help you find specific commands.

(Two-color Type)

Troubleshooting 3-5

To use the hex dump feature, follow these steps:

1. After you make sure that the printer is off, set DIP switch 1-2 to

.

ON

2. Turn on the printer while you hold down the
button; then release and press the

PAPER FEED

button quickly.

Note:

Releasing and pressing the PAPER FEED button should be

performed before the printer finishes initializing; otherwise the
printer begins the self test.

3. When the printer enters the hex dump mode, it prints
“Hexadecimal Dump.”

4. Run any software program that sends data to the printer. The
printer prints all the codes it receives in a two-column format.
The first column contains the hexadecimal codes and the
second column gives the ASCII characters that correspond to
the codes.
