1. PRODUCT INTRODUCTION
Thank you for purchasing the BIRCH BP-743 bar code printer. The attractive
desktop printer delivers superior performance at an economical price. Both
powerful and easy-to-use, this printer is your best choice among desktop direct
thermal and thermal transfer label printers. BIRCH also provides a wide range of
Auto-ID related products to meet your requirement.
This printer offers both thermal transfer and direct thermal printing at selectable
speeds of 1.5, 2.0 and 3.0 inches per second. It can accept a wide range of
media, including roll feed, die-cut, and fan-fold labels or tags for both thermal
transfer and direct thermal printing. All of the most frequently used bar code
formats are available. Fonts and bar codes can be printed in any one of four
directions. This printer provides a choice of five different sizes of alphanumeric
fonts. By using font multiplication, an even greater range of sizes is possible.
Smooth fonts can be downloaded from the user friendly label design software. In
addition, this printer is capable of independently executing BASIC programming
functions, including arithmetic, logical operation, loop, flow-control and file
management, among others. This programming capability provides the greatest
efficiency in label printing. The status of printer and error messages may either
be printed out or viewed on a monitor by means of the RS-232 connection.

2.5 Buttons and Indicators
PWR. (POWER) Indicator
The green PWR. indicator illuminates when the POWER switch is turned on.
ON-LINE Indicator
The green ON-LINE indicator illuminates when the printer is ready to print. When
PAUSE button is pressed, the ON-LINE indicator flashes.
ERR. Indicator (Error/Paper Empty)
The red ERR. indicator illuminates in the event of a printer error, such as memory
error, syntax error, and so forth. For a full list of error messages, please refer to
section 4.2, Error Messages.
PAUSE Button
The PAUSE button allows the user to stop a print job and then continue the
printing with a second depression of the button. By pressing the PAUSE button:
(1) the printer stops printing after the printing label, (2) the PAUSE LED flashes,
and (3) the printer will hold all data in memory. This allows for trouble-free
replacement of label stock and thermal transfer ribbon. A second depression of
the PAUSE button will restart the printer.
Note: If the PAUSE button is held down for more than 3 seconds, the
printer will be reset and all data of the previous printing job will be lost.
FEED Button
Press the FEED button to feed the label to the beginning of the next label.

3.7 Self Test
To initiate the self test mode, depress the FEED button while turning on the
printer power. The printer will calibrate the label length. If the label gap is not
detected within 7", the printer stops feeding labels and the media is treated as
continuous paper. In self test, a check pattern is used to check the performance
of the thermal print head. Following the check pattern, the printer prints internal
settings as listed below:
1. Printer model and firmware version
2. Mileage
3. Flash times
4. Check sum
5. Serial port setting
6. Code page setting
7. Country code setting
8. Print speed setting
9. Print density setting
10. Label size setting
11. Gap (Bline) width and offset setting
12. Backing paper transparence
13. File list
14. Memory available
When the self test is completed, the printer enters the dump mode. Please turn
the printer's power off and then on to resume normal printing.
20
3.8 Dump Mode
After the self test, the printer enters the dump mode. In this mode, any characters
sent from the host computer will be printed in two columns, as shown. The
characters received will be shown in the first column, and their corresponding
hexadecimal values, in the second. This is often helpful to users for the
verification of programming commands or debugging of printer programs. Reset
the printer by turning the POWER switch off and on.

4. USING THIS PRINTER
4.1 Power-on Utilities
There are three power-on utilities to set up and test printer hardware. These
utilities are activated by pressing the FEED or PAUSE button and turning on the
printer power simultaneously. The utilities are listed as below:
1. Self-test
2. Gap sensor calibration
3. Printer initialization
4.1.1 Self Test Utility
Install the label first. Press the FEED button and then turn on the printer power.
Do not release the FEED button until the printer feeds labels. The printer
performs the following items:
1.
2.
3.
4.
Calibrate label pitch
Print out thermal print head check pattern
Print the internal settings
Enter dump mode
Regarding the self-test and dump mode, please refer to section 3.7 "Self Test"
and section 3.8 "Dump Mode" for more information.
4.1.2 Gap Sensor Calibration Utility
This utility is used to calibrate the sensitivity of gap sensor. Users may have to
calibrate the gap sensor for two reasons:
1. The media is being changed to a new type.
2. Initialize the printer.
Note: The ERR. LED may flash if gap sensor is not calibrated properly.
Please follow the steps below to calibrate gap sensor:
1. Turn off the printer power and install blank labels (without any logo or
character) on printer.
2. Hold down the PAUSE button then turn on printer power.
3. Release PAUSE button when the printer feeds labels. Do not turn off printer
power until the printer stops and two green LEDs light on.
