light is off but nothing prints.
The interface cable may not be plugged in securely.
Check both ends of the cable between the printer and the
computer. Make sure your interface cable meets both the
printer and computer specifications.
Make sure that your software is properly set up for your
printer.
Printed output is not as expected.
If the printer does not print correctly, try the self test described
in Chapter
1.
If the self test works properly, the printer is all
right, and the problem probably lies in the computer, the
application program, or the interface cable. If the self test does
not work, contact your dealer or a qualified service person.
Check the printer settings within your software program.
Use the hex dump mode to pinpoint communication problems
between the printer and your application program. To enter the
hex dump mode, hold down the

and
Font
buttons
and turn on the printer. (Hold down the buttons until the
printer starts working; it takes a few seconds.) Then send data
from the computer. The printer prints the exact codes it receives
from the computer in hexadecimal format. You can analyze this
information to isolate problems.
The printer sounds like it is printing, but nothing prints.
The print head nozzles may be clogged. Hold down the
