Problem
Using an optional
interface, the printer
does not operate
properly.
The printer does not
print or the printout is
not what you expected.
Solution
The interface board may be loose or not
properly connected. Check that the
interface board is correctly inserted into
the connector on the main board. See
Chapter 5.
You may be trying to use an interface
with the wrong specification. Check the
specifications to make sure that you can
use the interface with this printer. See
Chapter 5.
The DIP switch settings may not be set
correctly. Make sure that DIP switches 2-3
and 2-4 are set for parallel, regardless of
whether the optional interface board is
parallel or serial. See Chapter 3. You can
also check the current DIP switch settings
by running the self test.
You may be trying to use a cable with the
wrong specification. Make sure that the
cable matches the specifications of the
interface.
The DIP switches or jumpers on the
interface board may be set wrong. See the
interface manual for the correct settings.
