OPERATION GUIDE  
CHAP. 3  
OPERA…  
FRONT PANEL  
The positions of the below mentioned switches and LED’ s are indicated  
in Fig. 10.  
“ON LINE” switch  
Switches the printer between “ON LINE” and “OFF LINE” status.  
Whenever the printer switches between “ON LINE” and “OFF LINE”, the  
buzzer gives one short beep (“ON LINE” and “OFF LINE” switching is possible  
only when paper is loaded in the printer).  
“FEED” switch  
When this switch is pressed and then released within 0.5 sec., the paper  
feeds one line. When this switch is held depressed for more than 0.5 sec., the  
paper feeds continuously (The above paper feed operation is possible for both  
“ON LINE” and “OFF LINE” modes).  
“POWER” LED (green)  
Lights when the power for the printer is on.  
“ALARM” LED (red)  
Lights when the paper is out. (If the paper is out, load a new roll and  
press the “ON LINE” switch.)  
Flashes when a mechanical error (motor lock etc.) occurs. The buzzer will  
give one short beep followed by a long beep. Mount the top cover properly and  
press the “ON LINE” switch. If the buzzer still sounds and the “ALARM” LED  
flashes, this signifies that a mechanical error has occurred. Locate the cause of  
the error and turn the power of the printer off and back on again to reset the  
printer (In case of a mechanical error, this restart does not definitely clear up the  
data buffer).  
“ON LINE” LED (green)  
LED lit: Printer is ON LINE  
LED off: Printer is OFF LINE  
LED flashes: Validation printing mode is set.

HEXADECIMAL DUMP MODE  
“ON LINE” + “POWER ON” (Turn the power on while holding the “ON LINE”  
switch depressed)  
CHAP. 3  
OPERA…  
Each of the signals sent from the computer to the printer will be printed  
out in hexadecimal code. This function allows you to check if a control code  
sent to the printer by the program being used is correct or not. The buzzer will  
sound once to indicate the printer is in hexadecimal dump mode. After the  
program has been run, the last line buffer should be flushed by pressing the “ON  
LINE” switch. To turn off the mode, it is necessary to turn off the printer  
completely.  
CLEAR PRINT BUFFER  
“FEED” + “ON LINE” + “POWER ON” (Turn the power on while holding both  
the “FEED” and “ON LINE” switches depressed)  
This operation clears the printer buffer (The buzzer gives two short  
beeps). When the printer power is shut off, the data content could degenerate  
and become unusable. For this reason, when the printer power is turned off and  
there are some left-over in the data buffer or if there is any scramble up in data  
receiving, perform the above operation to clear the data in the data buffer. Note  
that the data in the buffer can also be cleared by control code <CAN>.  
MICRO FEED  
“ON LINE” + “FEED” (Press the “FEED” switch while holding the “ON LINE”  
switch depressed when the printer is “OFF LINE”)  
As a result of this mode, the paper will feed in very small increments.  
VALIDATION PRINTING  
This printer can print one line of validation printing as described below.

2. Mount the top cover.  
CHAP. 3  
OPERA…  
3. Set the printer for the validation print mode through control codes to the  
printer. In this instance, the buzzer gives two short beeps.  
4. Make sure that the “ON LINE” LED is flashing.  
5. Align the right edge of paper with the right end of the tear bar then insert the  
paper from the top in front of the tear bar.  
6. The printer starts printing about 1 second after the paper is loaded.  
7. When printing is completed, pull the paper upward and remove it from the  
printer.  
Note: When printing a roll paper, it is recommended to adjust the lever at  
the same position as for validation printing.

·
·
The FEED and ON LINE switches will not operate normally during  
validation printing.  
When the printer receives an immediate execution command for peripheral  
units during validation printing, it executes the command when the validation  
print mode is canceled.  
·
Modes in effect before the validation printing (such as emphasized printing,  
inverted printing, expanded printing and underlining) are invalid during  
validation printing. But these become valid again after validation printing.

DATA STRUCTURE IN SERIAL INTERFACE  
DTR Mode  
This mode is accessed when the DIP switch 1-5 is ON. Signals are  
controlled using the DTR line as BUSY flag. If a printer errors do not occur after  
the power is turned on, the DTR signal line changes to “SPACE”. When the host  
computer confirms that the DTR signal line is set to “SPACE”, the host  
computer sends the data text via the RXD signal line to the printer. Also, the  
printer will set the DTR signal line to “MARK” when the empty space in the  
data buffer is below 256 bytes. After the host computer detects that the DTR  
signal line is at “MARK”, transmission of the data text is stopped. In this  
instance, data can still be received up until the data buffer becomes completely  
full. When the empty space in the data buffer is increased following printing  
(when the data in the data buffer is reduced to 256 bytes or less), the printer sets  
the DTR signal line to “SPACE”.

When the “paper out” detector senses the end of the paper, the printer

printer to “ON LINE”.  
Mechanical error  
Mechanical errors are detected when the motor locks or else and the unit  
will not print. Immediately after a mechanical error occurs, the printer sets the  
DTR to “MARK” and then sets the printer to “OFF LINE”. To cancel a  
mechanical error, close the front cover properly and press the “ON LINE”  
switch. If the buzzer sounds and the “ALARM” LED flashes at this time, then  
locate the cause of the error and turn the power for the printer off and back on  
again to reset the printer.

Framing error  
A framing error occurs when “SPACE” is detected at the stop bit. When a

printer prints out a “?” mark to indicate that the error occurred.  
Cash drawer open detection switch  
When pin 6 of the peripheral unit drive circuit connector is set “HIGH”,  
status bit 7 becomes “1”.  
X-ON/X-OFF Mode  
This mode is accessed when the DIP switch 1-5 is OFF. If printer errors  
do not occur after the power is turned on, the printer outputs an X-ON (DC1 by  
control code; 11H by hexadecimal data) signal on the TXD signal line of the  
printer which sends it to the host computer. When the host computer receives the  
X-ON signal, the host computer transmits the data to the RXD signal line of the  
printer. If data text is not sent from the host computer (even after transmitting  
the X-ON signal to the host computer), the printer outputs an X-ON signal at 3  
second intervals until the printer receives data. The printer starts outputting an  
X-OFF (DC3, 13H) signal when the empty space in the buffer reduces below  
256 bytes. When the host computer receives the X-OFF signal, it halts output of  
data (however, the printer can continue receiving data until the buffer becomes

When the “paper out” detector senses the end of the paper, the printer  
stops printing after printing a maximum of two more lines or on feeding the  
paper. The printer will set the DTR to “MARK” and set the printer to OFF LINE  
five seconds after a “paper out” condition is detected. To reset the printer after a  
“paper out”, load a new roll of paper into the printer and press the ON LINE  
switch to set the printer ON LINE.  
Mechanical error  
Mechanical error occurs when the motor locks or else and printing stops.  
After the error occurs, the printer outputs an X-OFF signal and stops printing.  
The printer sets the DTR signal to “MARK” and sets to “OFF LINE” five  
seconds after a mechanical error occurs. To reset the printer after a mechanical  
error occurs, close the top cover properly and press the “ON LINE” switch. If a  
buzzer sounds and the “ALARM” LED flashes at this point, locate the cause of  
the error and turn the power off and then back on to reset the printer.

When pin 6 of the peripheral unit drive circuit connector is set at  
“HIGH”, status bit 7 becomes “1”.  
STX-ETX Mode  
This mode is accessed from whichever DTR mode or X-ON/X-OFF  
mode. To set this mode, the data buffer must be empty. The host computer sends  
an “ENQ” code to the printer and acknowledges the printer status. Then, the host  
computer checks if the printer buffer is empty. After the host computer detects  
that the buffer is empty, a STX code and data are transmitted. After 1 block of  
data is transmitted, the host computer sends an ENQ code to the printer and then  
receives the printer status and check byte (horizontal parity for the printer). At  
this point, the host computer performs a status and horizontal parity check.  
When the host computer determines that there was no error, it transmits an ETX  
code which serves as end text code. After the printer receives the ETX code, data  
in the data buffer is printed out. If an error occurs, a CAN code is transmitted by  
the host computer (In this instance, the data which was previously sent to the  
buffer is cleared, thus, the host computer must retransmit the same data to the  
printer). A flowchart of this operation is illustrated as the following on next  
page.

This function differs depending on the setting of DIP switch 4.  
a) When the DC1, DC3 invalid mode is set (DIP switches 4-1 to 4-4 are all  
set to ON), the printer ignores this code.  
b) In the DC1, DC3 valid mode (with DIP switches 4-1 to 4-4 set to OFF),  
data following this code is ignored when the printer receives a<DC3>  
code.  
The deselect mode is canceled by <DC1> code.  
c) If the printer receives a <DC3> code during an addressable mode (with  
DIP switches 4-1 to 4-4 set to settings other than a) and b) above), the data  
following this code is ignored.  
Deselect mode can be canceled by a <DC1> n code.  
Note that addressable mode is valid only when the RS-422A interface  
option is installed.  
2. When using parallel interface printer  
Data following this code is ignored when the printer receives a <DC3> code.  
The deselect mode is canceled by <DC1> code.

DETAIL DESCRIPTION : Defines download characters from host  
computer. Up to 10 download characters can be defined and the defined  
character patterns can be stored in the printer’ s memory. Definitions of the  
variables in the command code are as follows:  
n1 and n2 represent the starting address and the ending address of the range  
of download characters respectively. When defining only one character, n1 =  
n2.  
Each set of m0 to m7 (for 7 x 9 fonts) or m0 to m5 (for 5 x 9 fonts) defines  
one download character. However, only either top 8 or bottom 8 print pins  
out of total 9 print pins of the print head can be used. m0 defines which set of  
pins to be used.  
APP. A  
m1 to m7 or m1 to m5 indicates each column of the download character  
pattern consecutively. Each bit in m1 to m7 or m1 to m5 defines a dot within  
that column to be printed (in vertical position). The relationship of each bit  
with each print pin combined with m0 can be illustrated in the following  
table, where the print pin # starts count at 1 from top of the print head:
