Procedure of Memory Switch Setting

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.

2. Open the front cover of printer.
3. Take out the old ribbon cassette if there is one.
4. Insert the new ribbon cassette as shown and pay particular attention to the placement of the ribbon behind the Printer Head.
5. During inserting the ribbon cassette, turn the knob clockwise again to make sure the ribbon moves freely in the cassette.
6. Close front cover of printer.

NOTES
Malfunctions and other problems may arise if other than specified ribbon cassettes are used in the printer. The Warranty may be void if other than specified ribbon cassettes are used. Contact your dealer or place of purchase for more information about proper ribbon cassettes.

Roll Paper Installation

1. To prevent data loss, make sure that the printer is not receiving data.
2. Open the rear cover by pushing the open button.
3. Remove the used paper roll core if there is one.
4. Insert the paper roll as shown.
5. Be sure to note the correct direction that the paper should come off the paper roll.
6. Pull out small amount of paper as shown. Then close the cover and tear off the extra paper by pulling it toward the front of the printer.

CAUTION
Do not touch the auto cutter blade when you open rear cover.

Changing the Paper Width

1. Open the rear cover.
2. Remove the frame paper control by loosing the two screws(3×6).
3. Reattach the frame paper control in you want. (Insert and tighten two screws(3×6) to reattach.)
4. Close the rear cover.
5. Change the Memory Switch setting for changing paper roll width. (See the instructions “Setting the Memory Switches”(3.1) in Chapter 3.)

Installing the Wall Mount (Option)

1. Turn the Set over and attach the Bracket hanger to the Frame base then tighten four screws.
2. Attach the Bracket mount to the wall firmly with the eight screws. Be sure that the Bracket attached properly to match the direction of arrow as shown. And the Bracket mount should be always fixed vertically.
3. Insert the Bracket hanger of Set to the Bracket mount as shown.

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 setting 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.

Hexadecimal Dumping

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. (A period (.) is printed for each code that has no ASCII equivalent.)
5. When the printing finishes, turn off the printer.

Appendix – Troubleshooting

This chapter gives solutions to some printer problems you may have.
ERROR LED Blinking Pattern
The printer stops all printer operations for the selected paper section, goes off line, and the ERROR LED blinks when an error is detected.
Errors that Automatically Recover

NOTES
These conditions are selected by MSW8-5, 8-8. When MSW8-5 (mapping of the cover open status) is off, the error hasn’t occurred but there is a “paper end error” instead. I MSW8-8 is off, this error is handled as an automatically recoverable error.
Print head temperature error is not abnormal.
Recoverable Errors
When a recoverable error occurs, after the cause of the error is removed, the printer can recover from the error by receiving an error recovery command without turning off the power.

NOTES
These conditions are selected by MSW8-5, 8-8. When MSW8-5 (mapping of the cover open status) is off, the error hasn’t occurred but there is a “paper end error” instead. If MSW8-8 is off, this error is handled as an automatically recoverable error.

Errors that are Impossible to Recover

NOTES
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.
The Printer does not Start Printing

1. Are any of the operation panel lights on, If no operation panel lights are on, check the following:
   • Make sure that the printer is turned on.
   • Make sure that the power supply cable is correctly plugged into the printer and to the power outlet.
2. If any of the lights are on, please check the following:
   • If the POWER LED is blinking, the printer is not ready yet.
   • Wait until the light quits blinking and the printer is ready to use.
   • If the ERROR LED is on (but not blinking), the printer is off line. Check to see that the covers are closed and check the paper state. See Chapter 5 for instructions on installing or replacing the paper roll.
   • If the ERROR LED is blinking, there is an error. In this case, turn off the printer for a few seconds and then turn it back on. If the light is still blinking, call your supervisor or service person.
   • If the PAPER OUT LED is on, check the paper roll in the printer. See Chapter 5 for instruction on installing the paper roll.

The Printer Stops Printing

• If the ERROR LED is on (but not blinking), the printer is off line. Check to see that the covers are closed and check the paper state. See Chapter 5 for instructions on installing or replacing the paper roll.
• If the ERROR LED is blinking, there is an error. In this case, turn off the printer for a few seconds and then turn it back on. If the LED is still blinking, call your supervisor or a service person.
• Turn off the printer and check for a paper jam. To clear paper jam, follow the steps below:
  • Turn off the printer and open the rear cover of the printer.
  • Remove the jammed paper and reload the paper roll as described in Chapter 5.

You want to Check the Operation of the Printer by Itself
Self test
Try to run the self test to check that the printer works properly. See the self test instructions in Chapter 8 to run the self test. If the self test does not work, contact your supervisor or a service person. If the self test works properly, check the following:

1. Check the connection at both ends of the interface cable between the printer and the computer. Also make sure that this cable meets the specifications for both the printer and the computer.
2. The data transmission settings may be different between the printer and computer. Make sure that the printer’s DIP Switch settings for data transmission are the same as the computer’s. You can see the printer’s interface settings on your self test printout.

NOTES
If the printer still does not print, contact your dealer or a qualified service person.
Printing is Poor
Check the state of ribbon cassette. If the ribbon cassette life ends, replace the ribbon cassette as described in Chapter 4.
NOTES
If the printer is still poor, contact your dealer or a qualified service person.
