To perform a self test, follow these steps:
1. Make sure that the printer is turned off and that the paper is
set on the front or rear tractor.
c CAUTION:
Whenever you turn off the power, wait at least five seconds
before turning it back on; otherwise you may damage the
printer.
2. While holding down the LF/FF Load or Tear Off button,
turn on the printer. The LF/FF Load button performs a
draft self test. The Tear Off button performs a near letter
quality (NLQ) self test.
In a few seconds, the printer starts the self test, in which a
series of characters is printed.
Note:
If you want to temporarily stop the self test, press the Pause
button. To resume the test, press the Pause button again.
3. To end the self test, press the Pause button to stop
printing. Tear off the page if necessary, and then turn off
the printer.
c CAUTION:
Do not turn off the printer while it is printing. Always press the
Pause button to stop printing and then turn off the printer.
Printing a Hex Dump
The printer can print data in hex dump mode, which allows
experienced users to find the cause of communication
problems between the printer and a software program. In hex
dump mode, the printer prints all data received as characters
in hexadecimal values.
To use hex dump mode, follow these steps:
1. Make sure that paper is loaded in the printer.
2. Hold down both the LF/FF Load and Tear Off buttons
while you turn on the printer.
3. Next, run a software program and send a print job to the
printer. Your printer prints all the codes it receives from the
software in hexadecimal format.
By comparing the characters printed in the right column
with the printout of the hexadecimal codes, you can check
the codes being received by the printer. If characters are
printable, they appear in the right column as ASCII
characters. Nonprintable codes, such as control codes, are
represented by dots.
4. To turn off hex dump mode, press the Pause button, and
then turn off the printer.
Cleaning the Printer
To keep your printer operating at its best, you should clean it
thoroughly several times a year. Follow these steps:
1. Turn off the printer and close all of its covers. Then remove
any paper as well as the paper guide. If you have installed
the optional pull tractor, perforation cutter, or paper cutter,
remove it.
2. Use a soft brush to carefully brush away all dust and dirt
from the outer case.
3. If the outer case or paper guide is still dirty or dusty, clean it
with a soft, clean cloth dampened with mild detergent
dissolved in water. Keep all of the covers closed to prevent
water from getting inside the printer.
w WARNING:
Be careful not to get water on the printer mechanism or
electronic components.
c CAUTION:
Never use alcohols or thinners to clean the printer. These
chemicals can damage the printer components as well as the
case.
Do not use a hard or abrasive brush.
Do not spray the inside of the printer with lubricants; unsuitable
oils can damage the mechanism. Contact your EPSON dealer if
you think lubrication is needed.
Transporting the Printer

repack it using the original box and packing materials as

Even when you need to carry the printer only a short distance,
do not carry it by yourself. The printer should always be carried
by two people holding the printer at the bottom.

printer. If any printer options are installed, remove them.
2. Unplug the power cord from the electrical outlet and the
