Problem
Solution
Using an optional
interface, the printer
does not operate
properly
(continued).
The printer does not
print or the printout is
not what you expected
(continued).
Two cables may be installed on the
printer; only one cable may be attached at
any time.
If the printer still does not operate properly after checking the above
points, run a self test of the interface to make sure that there are no
on-board defects. If any abnormality is found, contact your Epson
dealer.
Note: If you are still having problems after working through the
solutions in this section, you may want to try using the data
dump mode, a mode that helps advanced users determine the
causes of communication problems between the printer and the
computer. See Data Dump Mode in Chapter 3 for more
information.
