Printing a Hex Dump
If you are an experienced user or a programmer, you can print
a hexadecimal dump to isolate communication problems
between the printer and your software program. In hex dump
mode, the printer prints all data received from the computer
as hexadecimal values.
You can print a hex dump using either single sheets or
continuous paper.
Note:
Use paper that is at least 8.3 inches (210 mm) wide, such as letter- or
A4-size paper.
To print a hex dump, follow these steps:
1. Make sure paper is loaded and the printer is turned off.
Caution:
Whenever you turn off the printer, wait at least five
seconds before turning it back on; otherwise you may
damage the printer.
2. To enter hex dump mode, hold down both the
buttons while you press the
Load/Eject
turn on the printer.
3. Open a software program and send a print job to the
printer. Your printer prints all the codes it receives in
hexadecimal format.
If characters are printable, they appear in the right column
as ASCII characters. Nonprintable codes, such as control
codes, are represented by dots. By comparing the characters
printed in the right column with the printout of the
hexadecimal codes, you can check the codes the printer is
receiving.
4. To exit hex dump mode, press the
printing and the
Load/Eject
page(s). 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. Make sure the printer is turned off. Then remove any paper
loaded in the printer.
2. Remove the paper guide. If a pull tractor or an optional cut-
sheet feeder is installed, remove it.
3. Use a soft brush to carefully brush away all dust and dirt
from the outer case and paper guide.
4. If the outer case or paper guide is still dirty, clean it with a
soft, clean cloth dampened with mild detergent dissolved in
water. Keep the printer cover in place and lower the paper
guide cover until it lies flat on the top of the printer to
prevent water from getting inside the printer.
Caution:
Never use alcohols or thinners to clean the printer; these
chemicals can damage the printer components as well
as the case.
Be careful not to get water on the printer mechanism or
electronic components.
Do not use a hard or abrasive brush.
Do not spray the inside of the printer with lubricants;
unsuitable lubricants can damage the printer
mechanism. Contact an EPSON dealer if you think
lubrication is needed.
