Warning:
Never replace the print head yourself because other parts of the printer
must be checked at the same time.
Incorrect characters are printed.
Cause
Your printer and the
computer may not be
communicating correctly.
The wrong character table is
selected in your software.
What to do
Stop printing and contact your dealer
to have the print head replaced.
What to do
Make sure that you use the correct
interface cable and that the
communications protocol is
correct. See page 1-10 and your
computer documentation. If you
installed the optional serial interface
card, also see page 5-19.
Select the correct character table using
your software, the default-setting
mode, or the EPSON Remote! utility.
Note that the character table setting in
your software overrides the settings
made in the default-setting mode or
the EPSON Remote! utility.
