Chapter 1

Setup

This chapter guides you through unpacking and
identifying the parts of your portable printer. See
Chapter 2 for a detailed description of how to
operate the printer.

Unpacking

Carefully unpack the printer and accessories from
the shipping container. Check the individual parts
against the list of components in Table 1; if any
parts are missing or damaged, notify TSI
immediately.

Parts Identification

Power Switch

There are three positions for this switch: OFF, ON,
and CHARGE/AC.

1. Keep the unit switched OFF when not in use.

2. When set to ON, power will be supplied from

the internal rechargeable battery.

3. Switch to the CHARGE/AC position when

charging the internal battery. Also use this
position to operate the printer on power
supplied through the AC Adapter/Charger.

Indicator Lights

There are two indicator lights visible on the front of
the printer: POWER and BATT.LOW.

1. The POWER indicator lights when power is

switched on.

2. The BATT.LOW indicator lights when the

internal battery charge becomes low. This
indicator flashes when a paper jam occurs.

DIP Switch Setting

The DIP switch cover may be opened to examine
the settings of the six DIP switches. The switches
will be set at TSI for proper operation with the TSI
instruments. Switches 1, 2, and 4 should be down
(on) and switches 3, 5, and 6 should be up (off).

Chapter 2

Portable Printer Operation

This chapter explains how to operate the portable
printer.

Connecting the AC Adapter/Charger

The AC Adapter/Charger provided with the printer
is used for charging the internal battery in the
printer and for operating the printer. In order to
connect the AC Adapter/Charger to the printer,
follow these steps.

1. Set the POWER switch on the printer to

CHARGE/AC.

2. Insert the printer end of the AC

Adapter/Charger into the printer’s power
supply jack.

3. Plug the AC Adapter/Charger into an

appropriate power outlet.

CAUTION: To prevent shorting, do not touch

the tip of the DC plug.

When removing the AC Adapter/Charger, set the
POWER switch to OFF and unplug the AC
Adapter/Charger and then the DC plug.

3

Charging the Battery

The printer contains an internal rechargeable
battery. Because the battery charge is low at the
time of purchase, you will need to charge the
battery before use. To charge the battery, follow
these steps:

1. Set the POWER switch to CHARGE/AC.

2. Connect the AC Adapter/Charger as explained

in the previous section. Allow the printer to
charge for 15 hours.

3. When charging is over, set the POWER switch

to OFF.

Always observe the following to minimize
deterioration of battery performance.

• Do not charge continuously for over 24 hours.

• Charge within the temperature range of 40°F to

104°F (5°C to 40°C).

Chapter 2

CAUTION: DO NOT run the printer with the
switch in the CHARGE/AC position if the
battery is sufficiently charged to run the printer.
It is important to allow the battery to discharge
fully until the low battery indicator comes on
before charging again.

There are two reasons for this precaution. The
first is that leaving the printer switch in the
CHARGE/AC position may over-charge the
battery if it does not need charging. The
second reason is that NiCd batteries have a
tendency to develop a memory if they are not
allowed to fully discharge before being
charged again. Both of these conditions will
result in poor battery life.

If the battery becomes discharged while printing,
the BATT.LOW indicator will light. It is then time
to recharge the battery. To continue printing with a
discharged battery, it is necessary to connect the
AC Adapter/Charger and set the POWER switch on
the printer to CHARGE/AC.

Installing Paper

Before installing paper into the printer, it is
necessary to open the paper holder cover. To open,
place your thumb on the paper holder cover and
pull up and back.

To install paper into the printer, follow these steps:

1. Turn the POWER switch to ON.

2. Cut the end of the paper straight and square.

3. Open the paper holder cover.

4. Insert the front edge of the paper into the

insertion slot.

5. Press the PAPER FEED switch to advance the

paper. Keep the PAPER FEED switch
depressed until the end of the paper comes out
of the paper cutter.

A red line appears along the edge of the paper
when the remaining supply of paper becomes low.

When handling the thermal paper follow these
steps:

• Store in a dark place that is cool and dry.

• Do not rub with a hard object.

• Do not store near organic solvents.

Chapter 2

Test Printing

A test printing allows you to confirm that the
printer is operating correctly and that the DIP
switches are set correctly. When you perform a test
printing, the printer will automatically print several
lines of characters. The final six lines indicate the
DIP switch settings. Remember, for proper
operation with TSI instruments, DIP switched 1, 2,
and 4 should be ON and switches 3, 5, and 6 should
be OFF.

To execute a test printing, follow these steps:

1. Make sure paper is installed in the printer.

2. Set the POWER switch to OFF.

3. Set the POWER switch to ON while pressing

the PAPER FEED switch at the same time.

4. Release the PAPER FEED switch when

printing starts.

Do not switch the printer off during a test printing.
The printer will stop automatically after printing is
over.

Connecting the Printer to a TSI Instrument

An interface cable has been provided to connect the
printer to a TSI instrument. To connect the printer,
follow these steps:

1. Remove the plastic cover from the serial input

connector on the printer (if present).

2. Plug the printer end of the interface cable into

the 9-pin serial input connector on the printer.

3. Connect the other end of the interface cable

into the RS232 port of the host instrument.

Operating with a TSI instrument

Whenever you operate the printer with a TSI
instrument, always switch on the host instrument
before switching on the printer.

If you switch on the printer first, the printer may
print unreadable characters or a series of question
marks when you try to print data from the
instrument. If this happens, simply switch the
printer OFF and then ON again. There is no need
to switch off the host instrument.

Maintenance

Some important points to remember when
operating the Model 8925 Portable Printer are listed
below.

• Use the AC Adapter/Charger provided and

connect to an appropriate power source. Do
not use an AC adapter other than the one
provided.

• Do not drop the printer or expose it to

excessive shock.

• Avoid places subject to high or low

temperatures (see specifications).

• Do not expose printer to long periods of direct

sunlight.

• Avoid extensive use in areas where excessive

dust, corrosive gases, or solvent vapors are
being generated.

• Do not switch off the power when the printer

is printing.

Never attempt to dismantle or repair the printer
yourself.
