Epson Stylus 300 User Manual page 63

The PAUSE 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 your software is properly set up for your printer.
Ink cartridges do not last long enough.
See the information on page l-8.
Printed output is not what you expect.
If the printer does not print correctly, try the self test described
on page l-14. If the self test works properly, the printer is all
right and the problem probably lies in the computer, the
software, or the interface cable. (Be sure to use a shielded
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 LOAD/EJECT and FONT
buttons and turn on the printer. 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.
