LOADING PAPER

• Be sure to turn off the power for the printer.

• Press the two sides of the top cover near the rear part a little bit inward and

lift the top cover up from the rear end and remove it.

• Set DIP switch 2-5 to match the width of the paper to use (refer to Fig. 17 on

board layout for DIP switch setting).

DIP switch ON OFF

2-5

(All the switches in the DIP switch array are factory preset to ON)

• Release the lock levers of both the left and right paper guides and push the

paper guides outward to show the three sets of grooves on the paper guide
shaft. Insert the E - rings into the grooves corresponding to the paper width
(ref. Fig. 7 ). Push the paper guides inward to touch the E - rings and fix the
lock levers leaving a 0.5mm gap between each paper guide and each edge of
the paper to feed.

• Now, turn the power back on.

• Cut off the front edge of the roll paper perpendicularly. In case of roll paper

with its front edge stuck with a label or so, cut off the part containing the
label and then cut edge straight. If the label’s adhesive is allowed to remain
on the paper roll, it may stick onto the printer’s rollers, causing paper
misfeed.

• Hold the roll paper as shown in the illustration, then insert the top end of the

paper beneath the paper guide as far as it will go and press the FEED switch
on the control panel to feed the paper.

• When the front edge of the paper feeds out of the printer, release the FEED

switch. Next, insert the roll paper shaft into the center hole of the paper roll,
when the paper width is 2.25 or 3 inches, add the two spacers from each end

(the thinner spacer for 3” and the thicker for 2.25” both with the flat side
facing inward) and put the whole assembly onto the roll paper shaft holder
(ref. Fig. 8).

• Insert the top edge of the paper into the paper cut slot, then mount the top

cover by reversing the procedure for removing the top cover in previous
steps (ref. Fig. 9).

When the paper runs out, a buzzer will sound 4 times per cycle for 2 cycles.

Note 1. Remove the paper remaining in the printer by pressing the FEED switch

(If you remove the paper by hand, the paper could be wrinkled or slip
and cause a paper jam).

2. When the paper end mark appears on the paper, replace the roll paper
before it runs out.

OPERATION GUIDE

TM

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).

HEXADECIMAL DUMP MODE

CHAP. 3
OPERA…

“ON LINE” + “POWER ON” (Turn the power on while holding the “ON LINE”
switch depressed)

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.

Operation Method

TM

1. Open the top cover, pull the adjust lever one notch from standard position

toward the operation panel side. When you cannot find standard position,
push the lever as far as possible toward the rear, then pull it by 2 notches
after having pressed it down. The lever is now in standard position.

2. Mount the top cover.

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.

Other Considerations

• 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”.

Paper out

When the “paper out” detector senses the end of the paper, the printer
stops printing after printing a maximum of two lines or on feeding the paper.

out”, load paper into the printer and press the “ON LINE” switch to set the
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
framing error or a vertical parity error occurs for the data which is received, the
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

4 - 10

completely full). Output of the X-ON signal is resumed when the data in the
buffer is printed out and drops to below 256 bytes.

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.

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.

≤

n1 ≤ n2 ≤ 7FH, m0 = 00H or 80H

APPLICATION LIMIT : When the 15 CPI character size is set (the

default setting), printing of adjacent horizontal dots is not allowed.

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.
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:

bit # of m1 to m7 or m1 to m5 8 (MSB) 7 6 5 4 3 2 1 (LSB)
engage print pin # (when m0 = 00h) 2 3 4 5 6 7 8 9
engage print pin # (when m0 = 80h) 1 2 3 4 5 6 7 8

For example, the following hexadecimal codes received under 12 CPI will define
the characters at addresses A0h, A1h and A2h to be like the graphs below when
selected:

FUNCTION : 8 dot single density bit image
DEFINITION RANGE : 1

≤

DETAIL DESCRIPTION : This code executes 8 dot bit image print

determined by “n1”. The total number of bit image data bytes in one line is equal
to n1. The printer ignores any data bytes over the specified amount allowed in
one line. When the bit image print is finished the printer automatically returns to
the character mode. The relationship of the image data byte and the pin position
of the print head is as following, where the print pin # starts count at 1 from top
of the print head (the lowest pin # 9 is not used):

FUNCTION : 8 dot double density bit image
DEFINITION RANGE : 1

≤

n1 + 256 x n2 ≤ 400

APPLICATION LIMIT :

1. For double density bit image printing, dots cannot be printed overlapping

each other in the horizontal direction.

2. When printing one graphic image of a minimum of two lines with <ESC> “K”

or <ESC> “L”, feed the paper a minimum of one line before printing so that
the line spacing becomes identical between the lines.

DETAIL DESCRIPTION : This code executes double density bit image

printing (half dot printing) determined by n1 and n2. The total number of bit
image data bytes in one line is equal to n1 + n2 x 256. Refer to <ESC> “K” as to
the relation between the dot position and the bit number. The printer ignores any
data bytes over the specified amount allowed in one line. The printer does not
print adjacent dots. When the bit image printing is finished, the printer
automatically returns to the character mode.
