Memory Switch setting for Epson(ESC/POS) mode

This printer has “Memory Switch” set which is software switches. Memory Switch set has “MSW 2”, “MSW 8”,
“Customize value”, “Serial communication condition”. “Memory Switch setting utility” can change the Memory
Switch set to ON or OFF as shown in the table below (default: all OFF):

NOTES
The Memory Switch is available to be changed by three methods:
- Memory Switch setting utility
- Memory Switch setup mode (there are limitations on what can be changed)
- Control from ESC/POS command
- Some Memory Switch settings can be changed by the “Memory Switch setting mode”. See “Procedure of
Memory Switch setting”.

Settings of the Memory Switch are stored in the NV memory; therefore, even if the printer is turned off, the
settings are maintained. When you replace a SRP-270 with a SRP-275, you should adjust the MSW 8-5 to
OFF.

[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.

White/black inverted printing (1 Pass)
 White/black inversion (7 × 9 font print) + enhancing (2 passes)
 Upper line + Underline + enhancing (2 passes)
 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.
 “4”: Red (white/black inversion) printing
 “5”: Red (white/black inversion) printing cancelled.
When using  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  “-” 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.

8. 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.

9. 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.

Hexadecimal Dump
To terminate hexadecimal dump
Press FEED button three times

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

11. Appendix - Troubleshooting
This chapter gives solutions to some printer problems you may have.
11-1 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

cools.

NOTES
(*1) 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.
(*2) 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.

11-3 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:
1) Turn off the printer and open the rear cover of the printer.
2) Remove the jammed paper and reload the paper roll as described in Chapter 5.
3) Close the rear cover.
4) Turn on the printer.

11-4 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.

11-5 Printing is poor
Check the state of ribbon cassette. If the ribbon cassette life ends, replace the ribbon cassette as
described in Chapter 4.
