Description

Description

General

Bacharach’s portable wireless printer uses infrared technology to commu­nicate with other Bacharach instruments that are capable of transmitting
data using the Infrared Data Association (IrDA) standard.

The printer is designed around a patented easy-loading paper mecha­nism, which consists of a main cavity into which a paper roll is dropped
for loading. The thermal print head is at the front of the cavity and a
rubber roller is attached to the lid of the mechanism. When the lid is
closed, the paper is pinched between the rubber roller and the print-head
to give a close alignment and a consistent pressure.

Features

• Small size

• Quiet and fast printing

• Direct line thermal printing

• Typically 1,000 printouts from a fully charged battery pack

• Easy loading paper

• Easy maintenance and head cleaning

• User setable printer parameters using external pushbuttons

• Self-test function

AC Adapter / In-Car Charger

The supplied AC adapter (either 120 or 230 VAC) or 12 V in-car charger
can be used to either charge the battery pack, or both charge the battery
and run the printer when the battery is partially discharged.

Important! The AC adapter and in-car charger cannot
operate the printer with the battery pack removed, or when
the battery pack is completely discharged.

Belt Clip

If desired, the supplied belt clip and screws can be installed to allow the
printer to be attached to a vertical surface or carried on a belt.

Instruction 24-9422 1

Description

IrDA Printer

Power Switch

Use the Power switch located on the left side of the printer to turn the
unit ON and OFF (see Figure 1).

Indicator LEDs

There are two LEDs on the front panel that provide the following infor­mation about the printer’s status:

• Power (Green): The Power LED glows green when the printer is

turned ON.

• Battery (Red): The Battery LED glows red when the battery is being

charged. This LED flashes when the battery is fully charged, and turns
OFF when the battery charger is disconnected.

• Error (Green): The Power LED flashes once-a-second when: 1) the

printer is out of paper, 2) when the paper cover is opened, or 3) when
the printing head temperature exceeds 140 °F (60 °C).

Pushbuttons

There are two pushbuttons located on the front panel that perform the
following functions:

• FEED: Momentarily press this button to advance the paper. Pressing and

holding down the button causes the paper to feed continuously. This button
is also used to start the printer’s self test (refer to Section Self Test).

• SEL: Press this button to enter the printer’s set-up mode (refer to

Section Set-Up Mode).

Connectors

Two connectors located on the right side of the printer provide the follow­ing functions:

• Power: Connect the AC adapter or in-car charger to this connector to

charge the battery pack, or directly power the printer.

• RS-232C: Not used in conjunction with Bacharach instruments.

Description

Sensors

There are three sensors that perform the following functions:

• Paper Cover: When the paper cover is open the printer is disabled to

prevent damage to the print head. This condition is indicated by the
Power LED flashing.

• Paper Out: When the paper roll runs out, the printer is disabled to

prevent damage to the print head. This condition is indicated by the
Power LED flashing.

• IrDA: Located at the front of the printer, this sensor accepts the infra-

red signal from the instrument.

Operation

Precautions

To ensure the proper operation of the printer and prevent the possibility
of voiding the warranty, be sure to observe the following precautions:

• Avoid dirty or dusty locations, or those with excessive heat or humidity

• Choose a stable level or solid wall on which to mount the printer

• Use only the supplied power adapter to charge the battery pack

• Ensure that the AC adapter will be plugged into the correct source of

AC power

• Use only the supplied thermal paper or its replacement part

Self Test

The self-test mode checks the printer’s control circuit functions, setting
parameters, software version, and printer quality.

1. Before running the self test, make sure there is sufficient paper to
run the test (18" [46 cm]); the paper cover is closed; and that the
printer is switched OFF.

2. Press and hold down the FEED pushbutton; then switch ON the
printer to begin the test.

Note: The test can be aborted by switching OFF the printer.

3. The following typical information is printed, followed by the printer’s
complete character set:

Version : 1.1.6
Data bit : 8 bit
Parity : None
Baud rate : 9600 bps
Handshaking : DTR
Country : U.S.A.
Print mode : Text (upright)
Paper : Normal paper

Operation

IrDA Printer

Set-Up Mode

The printer has been set up at the factory with the following default
parameters:

Baud rate : 9600 bps
Handshaking : DTR
Country : U.S.A.
Print mode : Text (upright)
Paper : Normal paper
IrDA : IrDA-SIR

If necessary, the default parameters can be changed as follows:

1. With the printer initially switched OFF, press and hold down the SEL
pushbutton; then switch the printer ON.

2. The printer now goes into its set-up mode and prints its current
parameter status. Observe that the green Power LED flashes to
indicate that the printer is in its set-up mode.

Note: If no pushbuttons are pressed within 15 seconds, the
set-up mode is automatically terminated without changing
the original parameters.

3. Baud rate is first parameter printed. Pressing the FEED button
causes the value of that parameter to change in the sequence shown
in the following table.

SEL Button FEED Button

4. Press the SEL button to print the next parameter; then, if necessary,
use the FEED button to change that parameter to the desired value.

5. Once all parameters have been set, press and hold down the SEL
button then press the FEED button.

Operation

Using the Printer

Turn ON the printer and, if necessary, set it up as previously described
under the heading Set-Up Mode. Also ensure that the instrument that is
sending data to the printer is set up to operate in its IrDA print mode
(refer to the instrument’s instruction manual for set up information).

Align the printer’s infrared sensor to that of the instrument and begin
printing as described in the instrument’s instruction manual.

Maintenance

IrDA Printer

Maintenance

WARNING! Remove all electrical connections before perform-

ing any maintenance work.

Cleaning the Printer

External surfaces of the printer may be kept clean by simply wiping with
a damp cloth. Do not use any solvents that may attack the plastic case. Be
sure that the inside surfaces are kept dry at all times, and that the
external surfaces are thoroughly dry before re-making any electrical
connections.

Opening / Closing the Paper Cover

From underneath the printer, use your thumb and forefinger to push up
on the paper cover until it releases from its latches (see Figure 2.)

Close the cover by pushing down until it snaps into place.

Cleaning the Print Head

To maintain a good print quality, it is recommended that the print head
be cleaned at least once a year or up to once a month if the printer is used
heavily. The print head should be cleaned immediately, however, if the
print becomes visibly fainter due to contamination of the print head.

Clean the print head as follows:

Material Required:

• Isopropyl Alcohol

• Cotton swabs

Procedure:

1. Switch OFF printer.

CAUTION: Allow the print head to cool before cleaning,
otherwise damage to the print head may occur.

2. Open paper cover and remove paper roll.

8 Instruction 24-9422

IrDA Printer

3. Using a cotton swab dampened with alcohol, wipe the heating dots of
the print head. Be careful not to touch the heating dots with your

fingers.

4. Allow the alcohol to dry.

5. Reload the paper and close the paper cover.

Maintenance

Installing the Paper

Replace the paper when it runs out as indicated by the front panel green
Power LED flashing.

1. Open the paper cover as previously described.

2. Remove the spent paper core.

3. Drop in a new paper roll so that it will rotate in the direction shown
in Figure 2.

4. Insert edge of paper roll into slot in cover next to cutter; then close
cover. Remove any slack by pulling out about ½ inch of paper from
the printer.

Note: If there was unprinted data in memory when the
paper ran out, and the printer was not shut OFF, then the
printer will automatically go on-line and print the remaining
data 5 seconds after closing the paper cover.
