Setting Up the Printer 1-5

WARNING:

Make sure that you use the EPSON PS-170 power supply or
equivalent. Using an i ncorrect power supply may cause fir e or
electrical shock.

CAUTIONS:

When connecting or disconnecting the power supply from
the printer, make sure that the power supply is not plugged
into an electrical outlet. Otherwise you may damage the
power supply or the printer.

If the power supply’s rated voltage and your outlet’s voltage
do not match, contact your dealer for assistance. Do not
plug in the power cord. Otherwise, you may damage the
power supply or the printer.

1. Make sure that the printer’s power switch is turned off, and the
power supply’s power cord is unplugged from the electrical
outlet.

2. Check the label on the power supply to make sure that the
voltage required by the power supply matches that of your
electrical outlet.

3. Plug in the power supply’s cable as shown below. Notice that
the flat side of the plug faces down.

Note:

To remove the DC cable connector, make sure that the power
supply’s power cord is unplugged; then grasp the connector at the
arrow and pull it straight out.

Installing or Replacing the Paper Roll

Note:

Be sure to use paper rolls that meet the specifications. Do not
use paper rolls that have the paper glued to the core because the
printer cannot detect the paper end correctly.

1. Make sure that the printer is not receiving data; oth erwise, data
may be lost.

Adjustments and Settings

The TM-T88II Series are set up at the factory to be appropriate for
almost all users. It does, however, offer some settings for users with
special requirements.

It has DIP switches that allow you to change communication
settings, such as handshaking and parity check, as well as print
density.

The TM-T88II Series also have a near-end sensor for the paper. This
can give you a warning when the paper is almost out. If you find
that there is not enough paper remaining on the rol l when t he near­end detector is triggered, you can change the near-end sensor
setting.

See Appendix A if you need to make any of these changes.

light is blinking and the printer does not print.

First, turn off the printer and check for a paper jam. (See the paper
jam description on page 3-3.)

Troubleshooting 3-1

If there is no paper jam and the printer has been printing for quite a
while, the print head may be overheated. If the print head is
overheated, the printer will resume printing when the head has
cooled (usually within two or three minutes).

If there is no paper jam and the print head is not overheated, turn
off the printer a nd turn it back on after about 10 seconds. If the
ERROR light is still flashing, contact a qual ified service person.

ERROR

The

light is off, but nothing is printed .

Try to run the self test to check that the printer works pro perly . See
the self test instructions in Chapter 1 to run the self test. If the self
test does not work, contact your dealer or a qualified service
person.

If the self test works properly, check the following:

1. Check the connection at both ends of the interface cable
between the printer and the computer. Also make sure that this
cable meets the specifications for both the printer and the
computer.

2. The data transmission settings may be different between the
printer and co mputer. Make sure that the printe r’s DIP switch
settings for data transmission are the same as the computer’s.
You can print the printer’s interface settings using the self test.

If the printer still does not print, contact your dealer or a qualified
service person.

Printing is poor.

Paper dust on the heating element of the thermal print head can
lower the print quality. Try cleaning the print head as described
below:

3-2 Troubleshooting

Cleaning the print head

CAUTIONS:

After printing, the print head can be very hot. Be careful not
to touch it. Also let it cool before you clean it.
Do not damage the print head by touching it with your
fingers or any hard object.

1. Open the printer cover.

2. Clean the thermal element of the print head with a cott on swab
moistened with an alcohol solvent (ethanol, methanol, or IPA).

error state and begins the recovery operation automatically.

If the problem is not serious, the auto cutter returns to its normal
position without any intervention by the user.

Hexadecimal Dump

This feature allows experienced users to see exactly what data is
coming to the printer. This can be useful in finding software
problems. When you turn on the hex dump function, the printer
prints all commands and other data in hexadecimal format along
with a guide section to help you find specific commands.

To use the hex dump feature, follow these steps:

1. After you make sure that the printer is off, open the cover.

2. Hold down the FEED button while you turn on the printer.

3. Close the cover.

4. Run any software program that sends data to the printer. The
printer prints “Hexadecimal Dump” and then all the codes it
receives in a two-column format. The first column contains the
hexadecimal codes and the second column gives the ASCII
characters that correspond to the codes.

Notes:

With the optional RS-485 interface, DIP switches 2-7 and 2-8 are disabled.

•

Changes in DIP switch settin gs (excluding switches 2-7 and 2-8 inte rface reset

signals) are recognized only when the printer power is turned on or when the
printer is reset by using the i nterface. If the DIP switch setting is changed after
the printer power is turned on, the change do es not take effect until the
printer is turned on again or is reset.

If you turn on DIP switch 2-7 or 2-8 while the printer is turned on, the printer may

•

be reset, depending on the signal state. DIP switches should not be changed
while the printer power is on.

If the print density is set to level 3 or 4, the printing will be at the low speed.

•

In a low power consuption, printing speed is fixed to 70 mm/sec.

Changing the DIP switch settings

If you need to chang e settings, foll ow the steps belo w to mak e your
changes:

CAUTION:

Turn off the printer while removing the DIP switch cover to
prevent an electric short, which can damage the printer.

1. Make sure the printer is turned off.

2. Remove the screw from the DI P swi tch cov er. Then take off the
DIP switch cover, as shown in the illustration below.

DSW1
DSW2

3. Set the switches using a pointed tool, such as tweezers or a
small screwdriver.

4. Replace the DIP switch cover. Then secure it with the screw.

The new settings take effect when you turn on the printer.

A-6 Dip Switch and Paper Near End Settings

Adjusting the Paper Near End Detector

The paper near end detector detects when paper is almost gone by
measuring the diameter of the paper roll. The detector has two
settings.

Because of variations in paper roll cores, it is not possible for the
detector to measure exa ctly the length o f paper left on the roll when
the detector is triggered. Of the two settings, the factory setting
(lower) leaves the least amount of paper on the roll when the
sensor is triggered. If you want more paper left, c hange the setting
as described belo w.

Note:

The factory setting is based on a paper roll core with an outside
diameter of 18mm and an inside diameter of 12mm. If you use a
paper roll with a core with an outside diameter of more than 18mm,
it is better to change to the upper setting, as described below.

1. Open the printer cover, and remove the paper roll.

2. Loosen the adjusting screw and move the tab up to the upper
setting.

3. Tighten the adjusting screw, and check to be sure that the
detecting lever moves freely.

4. Replace the paper roll.
