IrDA Printer  
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 the Infrared Data Association (IrDA) standard.  
The printer is designed around a patented easy-loading paper mecha-  
nism, 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.

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 infor-  
mation 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 follow-  
ing 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.

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:

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.

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.  
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.
