Description  
Description  
General  
Bacharach’s portable wireless printer uses infrared technology to commu-  
nicate with other Bacharach instruments that are capable of transmitting  
data using either the Infrared Data Association (IrDA) standard, or HP  
protocol.  
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 load-  
ing. 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 align-  
ment and a consistent pressure.  
Features  
• Wireless printing  
• IrDA or HP protocol  
• Small, quiet, and fast printing  
• Direct line thermal printing  
• Easy loading paper  
• Easy maintenance and head cleaning  
• User setable printer parameters using external pushbuttons  
• Self-test function

sired printer parameter.  
Sensors  
Paper Out: When the paper roll runs out, or when the paper cover is  
opened, the printer is disabled to prevent damage to the print head. This  
condition is indicated by the Error LED flashing red.  
Infrared Sensor: Located at the front of the printer, this sensor  
receives the infrared output of an external instrument.

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 surface to place the printer  
• Use only alkaline batteries  
• Use only the supplied thermal paper or its replacement part  
Self Test  
The self-test mode checks the printer’s control circuit functions, setup  
parameters, software version, and print 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. With the printer initially switched OFF, press and hold down the FEED  
pushbutton, and 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:

If necessary, the default parameters can be changed as follows:  
1. With the printer initially switched OFF, press and hold down the SEL  
pushbutton, and then switch ON the printer.  
2. The printer now goes into its set-up mode as indicated by the red LED  
flashing. At this time all of the printer’s current parameter settings are  
printed, followed by the first parameter that can be modified.  
Note: If no button is pressed within 15 seconds, the set-up  
mode is automatically terminated without changing the  
original parameters.  
3. Baud rate is the first parameter printed. Pressing the FEED button  
causes the value of that parameter to change in the sequence shown in  
the following table.

4. Press the SEL button to print the next parameter, and then use the  
FEED button to change that parameter to the desired value.  
5. Repeat Step 4 as necessary to change all desired parameters.  
6. Once all parameters have been set, press and hold down the SEL button,  
and then press the FEED button to save the new settings; after which,  
the message “Data Keeping, Setting mode END !!” should be printed.  
Using the Printer  
See Figure 2. Turn ON the printer and observe that the Power LED should  
glow green.  
Align the printer’s infrared sensor to the infrared output of the external  
instrument. The printer should not be more than 18 inches (45 cm) away  
from the instrument, at an angle of no more than 30 degrees.  
Begin printing as described in the instrument’s instruction manual.  
Tip: If the printer does not print, or if random characters  
are printed, then check that the baud rate and communi-  
cation protocol (IrDA-SIR or HP-Ir) settings of both the  
printer and instrument are set to the same values.

Maintenance  
Battery Installation  
Install four ‘AA’ alkaline batteries as follows:  
1. Turn OFF printer.  
2. Unlatch and remove battery cover from bottom of printer.  
3. Remove old batteries and dispose of them properly.  
4. Insert four ‘AA’ alkaline batteries, observing the polarity marked inside  
the battery compartment.  
5. Install battery cover.  
Paper Installation  
When the printer runs out of paper as indicated by the front panel red  
LED flashing, install a new paper roll as follows:  
1. Lift up paper-cover latch, and then open paper cover as shown in  
Figure 3.  
2. Remove spent paper core.  
3. Drop in a new paper roll so that it will rotate in the direction shown.  
4. Close paper cover so that the paper is pinched between the paper roller  
and print head. Remove any slack by pulling out about ½ inch of paper  
from 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 print the remaining data 5 sec-  
onds after closing the paper cover.

Maintenance  
IrDA Printer  
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.  
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.  
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.  
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.
