Problem

Solution

When you use an

optional interface,

the printer does not

operate as expected.

The printout is garbled

or the printer does not

print.

The interface may not be configured

correctly. If you are using a serial

interface, make sure that both the

computer and printer are set to use the

same number of data bits per word and

that they both use the same parity, baud

rate, and number of stop bits. See your

computer manual for the correct

settings.

You may also need to change the DIP

switch settings of your interface board.

Before changing these settings, however,

make sure the printer is turned off. See

Chapter 4.

The optional interface may not be

installed correctly. Turn off the printer

and unplug the interface cable and

power cable. Then check to see that the

mating connector of the interface is

plugged into the main board correctly.

See Chapter 4.

You may be using the wrong interface

cable. Check with your dealer to make

sure you have the right cable. Also make

sure that you are using a shielded cable.
