KeysThere are two keys on the console: key 1, on the left and key 2, on the right. Their functionsare as follows:

KEY 1 Forces a document insertion from the top.

With the document inserted, advances the document by one line feed.

KEY 2 Forces a document insertion from the front.

With the document inserted, advances the document by one line feed.

Holding this key down for a few seconds expels the form that is present.

Keys 1 and 2 also have other functions (see chapter on SETUP from the OperatorConsole)

LED IndicatorsThere are five LED indicators on the console, indicating respectively:

LED 1 - ON Lit, indicates printer powered electrically.

LED 2 -error

Lit, indicates printer locked.Flashing, indicates a mechanical error or paper jam.(*)

LED 3 Lit, indicates a document was inserted from the top.Flashing, indicates that the top feeder is active.

LED 4 Lit, indicates a document was inserted from the front.Flashing, indicates that the bottom feeder is active.

LED 5 Flashing, indicates a document ejected from the print area.

(*) See also the section Console Diagnostics , which illustrates the error or failuresignals provided by the LEDs and proposes suitable remedial action.

SETUP from the Operator Console 3-1

3. SETUP from the Operator Console

IntroductionThe printer’s setup is used to access the factory configuration parameter settings. Theseparameters are already scheduled according to some predefined values (or those already setat factory level) and are used to provide special applications on the machine or the optionwhich has already been installed. The parameters used in the printer setup may be altered inorder to print according to user needs.

In order to avoid printer malfunction, when you prepare to change the parameters using thesetup, make sure that you are fully aware of all consequences of the changes you intend tomake. Call the technical support service only if absolutely necessary.

How to Access the Setup

Simply, you can access the setup mode tur ning on theprinter with the Key 2 pressed.

The printer is now in setup mode and therefore prints, on the slip paper, some data includingthe list of the setup parameters and the values which were previously set (not necessarily theinitial ones), the description of keys 1 and 2, and the first of the four menus available (if theprinter communication port is the serial port).

HT Horizontal tab

Hexadecimal code: 09

Moves the print position to the next horizontal tab position. This command is ignored unless the nexthorizontal tab position has been set.

LF Print and line feed

Hexadecimal code: 0A

Prints the data in the print buffer and feeds one line.

The amount of paper fed per line is based on the value set using the line spacing command.

The default setting is 1/6 inch.

FF Print and eject slip paper

Hexadecimal code: 0C

Prints the data in the print buffer and ejects the slip paper.

Notes: - The command is enabled only when slip paper is selected for printing.

- Paper ejection continues until the paper is completely ejected. When the slip ejectionlength has been set by ESC C, the specified length is ejected, regardless of the slipejection sensor.

- After the slip is ejected, the printer selects the default paper type for ESC c 0 .

- The slip is ejected in the direction specified by ESC F.

CR Carriage return

Hexadecimal code: 0D

When auto line feed is enabled, CR functions in the same way as LF.

When auto line feed is disabled, CR prints the data in the print buffer and does not feed the paper.

With a serial interface, auto line feed is disabled.

With a parallel interface, whether enabling or disabling the auto line feed can be selected by the SETUP

CAN Cancels print data in page mode


In page mode, deletes all the print data in the current printable area.


DLE EOT n Real-time status transmission

Hexadecimal code: 10 04 n

Range: n =1, 2, 3, 5

Transmits the selected printer status specified by n in real time, according to the following parameters:

n=1 Transmit printer statusn=2 Transmit off-line statusn=3 Transmit error statusn=5 Transmit slip paper status

This command is ignored during a process of transmitting the check paper reading result (only with theMICR reader).

With a serial interface model, this command is executed even when the printer is off-line, the receivebuffer is full, or an error occurs.

With a parallel interface model, this command is not executed in the following status, because theprinter is busy and unable to receive data from the host computer:

• Receive buffer is full when DIP switch 2-1 is set to ON.

• Printer is off-line, an error occurs, or receive buffer is full when DIP switch 2-1 is set to OFF.

DLE ENQ n Real-time request to printer


Range: n =1-3

Responds to a request in real time from the host computer, specified by n as shown below.

n can be set to 1 or 2 only when a recoverable error occurs.

This command is also executed to recover from a recoverable error when the printer is disabled by ESC=.

For the printer with the MICR reader, n can be set to 3 only when the printer is in the check paper orcleaning sheet insertion waiting status.

The check paper or cleaning sheet insertion waiting status can be confirmed by the DLE EOT BScommand.

During transmitting check paper reading result, this command is ignored.

When a recoverable error occurs, after removing a cause of an error, the printer can recover from anerror without turning off the power.


With a parallel interface model, this command is not executed in the following status because the

printer is busy and unable to receive data from the host computer:

• Receive buffer is full when DIP switch 2-1 is set to On.

• Printer is off-line, an error occurs, or receive buffer is full when DIP switch 2-1 is set to Off.

ESC & y c1 c2 [x1 d1...d(y × x1)]…[xk d1 … d(y × xk)] Define user-defined characters


Range: y=1c1-c2=32-126x=0-12 (for the font A)x=0-9 (for the font B)d1...d(y × xk) =0-255k = c2-c1+1

Defines user-defined characters from character code c1 to c2.

y and x are the configuration of a user-defined character.

y specifies the number of bytes in the vertical direction. x specifies the number of dots in the horizontaldirection.

Character codes from the alphanumeric characters (20H (decimal 32) to 7EH (decimal 126)) can bedefined by c1 and c2.

Data (d) specifies a bit printed to 1 and not printed to 0.

As the default, user-defined characters are not defined and the internal character set is printed.

Once the user-defined characters have been defined, they are available until ESC ?, or GS *, or ESC@ is executed; the user-defined characters are redefined; the power is turned off; or the printer is reset.

When this command is executed, the user-defined bit image is canceled.

Range: y=1c1-c2=32-126x=0-6 (5x7 font)x=0-10 (7x7 font)d1...d(y × xk) =0-255

Defines user-defined characters from character code c1 to c2.

y and x are the configuration of a user-defined character.

y specifies the number of bytes in the vertical direction. x specifies the number of dots in the horizontaldirection.

Character codes from the alphanumeric characters (20H (decimal 32) to 7EH (decimal 126)) can bedefined by c1 and c2.

Data (d) specifies a bit printed to 1 and not printed to 0. As the default, user-defined characters are notdefined and the internal character set is printed.

Once the user-defined characters have been defined, they are available until ESC @ is executed; theuser-defined characters are redefined; the power is turned off; or the printer is reset.

When this command is executed, the user-defined bit image is canceled.

Command Interpreter and Character Sets 6-1

6. Command Interpreter and Character Sets

EmulationsPrinters interpret the data they receive from the line in the form of special code sequences. If any ofthese sequences are sent, the printer performs the function that it represents. There is no commonmethod of controlling data. The leading printer manufacturers have created their own control"standards" according to the printing technology, applications to be used, etc. Other manufacturershave adapted to these standards, by making printers that behave exactly like ("emulate") the originalprinters; hence the concept of emulation.

To be compatible with various standards, a printer must be flexible and versatile. Your printer isparticularly so, as it can operate in several different emulations.

This printer operates with a set of codes divided into separate areas:

• Epson TMU 590 emulation environment

• Epson TM 295 emulation environment

The Epson TMU 590 command set is the most complete and comprises all the commands of theprinter in its full configuration.

The Epson TMU 295 emulation ensure continuity with the past, for users replacing their old EpsonTM 295 with the new TM 295.

Character SetsIn the character set, the firmware assigns a specific printable character to each byte of data. Acharacter set may contain up to 255 different characters. The first 128 characters (from code 0 to127) are standardized and represent the USA ASCII character set, which excludes all the Europeannational characters and semigraphic symbols as well.

The assignment of codes 128 to 255 varies from one country to another, from one type of hardwareto another, from one operating system to another and often according to the application programused. Before selecting a character set, read the documentation provided with your operating systemand application carefully.

The section "Printable character set tables" indicates the codes that correspond to the characters inthe resident character sets.
