l
The printer may not be securely connected to the computer.
Check both ends of the cable between the printer and the
computer.
l
Your software’s font, page layout, printer port, or other printer
settings may not be selected properly. Make sure your
software is correctly set up for your printer and that you
specify continuous-feed paper as the type of form.
l
If the printing is too high or low on the page, adjust it by
following the instructions in the sections in Chapter 2 on
adjusting the top of form position and adjusting the printing
position.
l
Your application program may be changing the SelecType or
DIP switch settings. Use the program’s setup procedure to
remove the interfering codes, or use the printer control codes
for your application program instead of SelecType or DIP
switches. See your software manual for more information on
removing interfering codes. Also, for more information on
sending printer commands, see the section on sending
commands to the printer in Chapter 4.
l
Make sure that the DIP switches are set correctly for use with
the built-in parallel or serial interface. See the section on DIP
switch settings for interface type, parity, and baud rate in
Chapter 3. You can also check the DIP switch settings by
running the self test. (See Chapter 1.)
l
If you are using an optional interface board, make sure that
DIP switches 2-5 and 2-6 are set for parallel, regardless of
whether the optional board is parallel or serial. See the section
on DIP switch settings for interface type in Chapter 3. Also,
make sure that the DIP switches on the interface board are set
according to the instructions in the interface board manual.
