The print head is damaged. Stop printing and contact your dealer
to have the print head replaced.

Warning:
Never try to replace the print
head yourself because other
parts of the printer must be
checked at the same time.
Incorrect characters are printed.
Cause What to do
Your printer and the
computer may not be
communicating correctly.
Make sure that you use the correct
interface cable and that the
communications protocol is correct.
Refer to the Setup Guide and your
computer documentation. If you
installed the optional serial interface
card, also see “Interface Cards” on
page 5-21.
The wrong character table is
selected in your software.
Select the correct character table in
your software or the printer’s default
settings. Note that the character table
setting in your software overrides the
settings made in the default-setting
mode.
The font or characters set in your application software cannot
be printed.
