▌1.8 Using the operation panel

Most of the functions of this printer are governed by software, but you can monitor the printer s status by

looking at the lights on the control panel and for some procedures you will use the buttons.

• Control panel

- POWER LED (Green Color)

This indicator light is on when the power is turned on. It blinks when the printer is in the self

test printing standby state. Always wait until this indicator light stops blinking before you

start using the printer and before you turn it off.

- ERROR LED (Red Color)

When this indicator light is on (but not blinking), it means that the printer is out of paper or

almost out of paper or the printer covers are open. When this light blinking, there is an

error. (See "ERROR LED blinking pattern" (2.1) in Chapter 2.) If you see this light blinking,

turn off the printer for a few seconds and then turn it back on. If the light is still blinking, call

your supervisor or a service person.

- PAPER OUT LED (Red Color)

When this indicator light is on, it means that the paper near end. Replace the new paper

roll. When ERROR and PAPER OUT indicator lights are on it means paper end. Install the

paper roll.(See "Installing paper roll"(1.5)in Chapter 1.)

- FEED button

Use this button to feed paper or to start self test and for hexadecimal dump mode.

(See the instructions "Self test" (1.7) in this chapter for self test.)

(See the instructions "Hexadecimal dump" (2.6) in Chapter 2 for hexadecimal dump mode.)

1-8

▌1.9 Self test

The self test let you know if your printer is operating properly. It checks the printing quality, ROM version,

DIP Switch settings, memory switch settings and statistic data.

The test is independent of any other equipment or software, so it is a good idea to run it when you first set

up the printer or if you have any trouble. If the self test works correctly, the problem is in the other equipment

or the software, not the printer.

• Running the self test

1) Make sure the printer is turned off and the printer cover is closed properly.

2) While holding down the FEED button, turn on the printer and continue to hold until the paper begins to

feed. The self test prints the printer DIP Switch settings and memory switch settings. And cuts the paper

and pauses. (The power light blinks.)

3) Press the FEED button to continue printing the statistic data.

4) Press the FEED button to continue printing the rolling ASCII pattern.

5) The self test mode terminates after printing the rolling ASCII pattern automatically.

▌2.5 Printing is poor

Check the state of ribbon cassette. If the ribbon cassette life ends, replace the ribbon cassette as

described in Chapter 1.

NOTES

If the printer is still poor, contact your dealer or a qualified service person.

▌2.6 You want to check a software program

• Hexadecimal dump

This feature allows experienced users to see exactly what data is coming to the printer.

This can be useful in finding software problems. When you turn on the hexadecimal dump function, the

printer prints all commands and other data in hexadecimal format along with a guide section to help you

find specific commands.

• To use the hexadecimal dump feature, follow these steps:

1) After you make sure that the printer is off, open the rear cover of the printer.

2) Hold down the FEED button while you turn on the printer.

3) Close the rear cover.

4) Run any software program that sends data to the printer. The printer prints "Hexadecimal dump" and

then all the codes are received in a two column format. The first column contains the hexadecimal

codes and the second column gives the ASCII characters that correspond to the codes.

Hexadecimal Dump

To terminate hexadecimal dump

Press FEED button three times

▌3.2.2 Memory Switch setting for Star mode

• Settings

Memory Switches are from MSW 0 to MSW 8. They are stored in non-volatile memory (flash memory). To

change the settings, send the following commands from the host.

[Name] Set Memory Switch

[Code] ASCII ESC GS # m N n1 n2 n3 n4 LF NUL

Hexadecimal 1B 1D 23 m N n1 n2 n3 n4 0A 00

Decimal 27 29 35 m N n1 n2 n3 n4 10 0

[Defined Region] m = "W", "T", ",", "+", "-", "@"

"0" ≤ N,n1,n2,n3,n4 ≤ "9",

"A" ≤ N,n1,n2,n3,n4 ≤ "F"

[Function] Sends command to write after defining Memory Switch using the definition command

specified by the following classes to set the Memory Switch. The printer is automatically

reset after writing the setting defined by that command to the non-volatile memory.

Do not turn off the power to the printer while sending commands to the non volatile

memory. Doing so will destroy the Memory Switch setting. It is also possible for all Memory

Switch settings to become offset to their initial, default settings.

Consider the life of the non-volatile memory and avoid over-use of this command.

1 0 <Option 2> Upper line + Underline + enhancing (2 passes)

1 1 <Option 3> Upper line + Underline + double tall expanded + enhancing (4 passes)

This setting functions to specify adornments when the subsequent red (white/black inversion) print

command is set. It is a substitute function for the conventional red/black (white/black inversion) printing.

<ESC> “4”: Red (white/black inversion) printing

<ESC> “5”: Red (white/black inversion) printing cancelled.

When using <ESC> 5 to cancel adornments, it returns to the previously set adornments. (Adornments

such as underline, upper line, double-tall expanded and enhancing are cancelled if there is no command

to set them (for example the <ESC> “-” 1 specification for underlines).)

This setting is enabled only for ANK characters and block characters. It is disabled for IBM block

characters and Chinese characters composed of 12 dot vertical characters (IBM block characters and

Chinese characters do not have adornment with this command).

- Precautions for selecting Option 1.

1) Prints white/black inverted characters using 7 × 9 fonts regardless of the current font size setting.

2) Inserts a one dot string of black printing to the head of the white/black inverted characters.

3) Printing data created on a conventional red/black printer, using 1 and 2 above, there are cases in

which the printing position will shift to the right and a line of printable characters reduced.

(For example, to write 42 digits of red print data using conventional a 7 × 9 font, there is a line feed at

the 35th digit, and the remaining 7 digits are printed on the next line.)

4) Download defined characters defined with 7 × 9 fonts are printed regardless of the current font setting

(7×9/9×9).

5) MSW 3-6 must not be set to 1 (ANK character count = many). (This will cause a while line to appear

between characters.)

- Precautions for selecting Option 2 and Option 3.

1) Do not apply an upper line or an underline to characters when rotating 90 or 270 degrees.

▌4.1 Command notation

XXXX

[Name] The name of the command.

[Format] The code sequence.

[Range] Gives the allowable ranges for the arguments.

[Description] Describes the command’s function.

[Notes] Provides important information on setting and using the printer command, if necessary.

Item(s) marked with * indicates "important notice".

[Default] Gives the default values (if any) for the command arguments.

[Reference] Lists related commands.

Hex indicates the hexadecimal equivalents.

Decimal indicates the decimal equivalents.

[ ] k indicates the contents of the [ ] should be repeated k times.

▌4.2 Explanation of term

Item Description

Reception buffer

The reception buffer is a buffer that stores, as is, the data received from the host (the

reception data). The reception data is stored in the reception buffer temporarily, and is then

processed sequentially.

Print buffer The print buffer is a buffer that stores the image data to be printed.

Print buffer full

This is the state where the print buffer is full. If new print data is input while the print buffer is

full, the data in the print buffer is printed out and a line feed is executed. This is the same

operation as the LF operation.

Start of line

The start of line state satisfies the following condition:

There is no print data (including spaces and portions of data skipped due to HT) currently in

the print buffer.

Printable area The maximum range within which printing is possible under the printer specifications.

Inch A unit of length. One inch is 25.4mm.

MSB Most Significant Bit

LSB Least Significant Bit

▌4.3 Exception processing

• Undefined codes

This term refers to the codes ranging from 00H to 1FH in the character code table. If a code in this range

that is not defined as a command is input, that code (one byte) is read in and discarded, and subsequent

data is processed as normal data.

Example : 30H, 31H, 03H, 32H, 0AH, 33H

If the above data string is input, the printer reads in and discards "03H" as an undefined code.

Note that 0AH is defined as a command (LF). As a result, the data string that is actually processed is: 30H,

31H, 32H, 0AH, 33H

• Undefined commands

If the data following ESC (1BH) or GS (1DH) is not defined as a command, then the two bytes (ESC/GS and

the code that follows) are read in and discarded.

Example : 30H, 1BH, 22H, 31H, 32H

If the above data string is input, the printer discards the data 1BH and 22H as undefined commands.

As a result, the data string that is actually processed is: 30H, 31H, 32H

• Settings outside the defined range

If a value outside of the defined range is input for a command that takes parameters, that command is

ignored and the previous value for that setting remains unchanged. In the case of a command that takes

multiple parameters, command processing is halted the moment that a value outside of the defined range is

input and subsequent values are processed as normal data.

Example : 1BH, 52H, 15H

If the above data string is input, 1BH and 52H are defined as a command (ESC R), but the parameter 15H is

outside of the defined range. As a result, the printer reads in and discards the data string 1BH, 52H, 15H.

Accordingly, the previously set international character set is not changed.
