1-6. Using the control panel

Control panel

Power (LED)

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.

This indicator light is on when the power is turned on.
It blinks when the printer is in the self test printing stanby state.
Always wait until this indicator light stops blinking before you start using
the printer and before you turn it off.

Error (LED)

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 is blinking, there is an error. If you see this light is 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.

Cartridge (LED)

The right indicator is for the right cartridge and the left indicator for the left
cartridge. If the printer is a single color printer, the left cartridge indicator will be
used. In the most cases, the left cartridge is back, and the right is a color.
This indicator light (LH/RH) blinks when the cartridge is almost out of ink and
stays on when the cartridge (s) is removed.

Clean (BUTTON)

Use this button to clean the printer head.
(See the instructions “Printing is poor” (2-4) in chapter 2 for Cleaning
The Printer Head.)

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” (2-5) in chapter 2 for hexadecimal
dump mode.)

1-7. Self test

The self test lets you know if your printer is operating properly.
It checks the control circuits, printer mechanisms, print quality,
ROM version, and DIP switch settings.

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.

2-1. The printer does not start printing.

Are any of the control panel lights on?
If no control panel lights are on, check the following:

This chapter gives solutions to some printer problems you may have.

Running the self test

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

2) Turn on the printer, while holding down the Feed button, and then

continue to hold until the paper begins to feed.

3) Press the Feed button. The self test prints the printer settings

and then cuts the paper, and pauses. (The power light blinks.)

4) Press the Feed button to continue printing.

The printer prints rolling ASC II pattern, nozzle pattern,
receipt pattern, NV bit image.

5) The self test automatically enters the hexadecimal dump mode.

6) Power off to terminate self mode.

4) If the printing quality has not improved, repeat this process 2-3 more times.
If the printing quality has not still improved, replace the ink cartridge.
If, after the new ink cartridge has been installed, the printing quality has not still
improved, call your supervisor or a service person.

2-3. 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 1 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:

If the printer still does not print, contact your dealer or a qualified service person.

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.

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 front cover of the printer.

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

3) Close the front cover.

4) Run any software program that sends data to the printer. The printer prints
“Hexadecimal Dump” and then all the codes it receives 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.

5) When the printing finishes, turn off the printer.

A period(.) is printed for each code that has no ASCII equivalent.

3-1. Setting the DIP switches

DIP switch functions

DIP - SW1

Your printer has two sets of DIP switches.
The functions of the switches are shown in the following table.

EPSON-KP(EPSON Kitchen Printer mode)

HT

[Name] Horizontal tab

[Format] ASCII HT

Hex 09
Decimal 10

[Description] Moves the print position to the next horizontal tab position.

[Notes]

This command is ignored unless the next horizontal tab position
has been set.

Horizontal tab positions are set with ESC D.

The default tab positions are at intervals of 8 characters
(columns 9, 17, 25..) for the font B (12 x 12).

[Reference] ESC D

LF

[Name] Print and line feed

[Format] ASCII LF

Hex 0A
Decimal 10

[Description] Prints the data in the print buffer and feeds one line based on the

current line spacing.

[Note] This command sets the print position to the beginning of the line.

[Reference] ESC 2, ESC 3

CR

[Name] Print and carriage return

[Format] ASCII CR

Hex 0D
Decimal 13

[Description] This command prints the data in the print buffer and does not feed the paper.

[Note] Sets the print starting position to the beginning of the line

[Reference] LF

DLE EOT n

[Name] Real-time status transmission

[Format] ASCII DLE EOT n

Hex 10 04 n
Decimal 16 4 n

[Range] 1 ≤ n ≤ 4

[Description] Transmits the selected printer status specified by n in real time,

according to the following parameters:
n = 1: Transmit printer status
n = 2: Transmit off-line status
n = 3: Transmit error status
n = 4: Transmit paper roll sensor status

[Notes]

This command should not be used within the data sequence of
another command that consists of 2 or more bytes. For example,
If you attempt to transmit ESC 3 n to the printer, but DTR (DSR
for the host computer) goes to MARK before n is transmitted
and then DLE EOT 3 interrupts before n is received, the code
<10>H for DLE EOT 3 is processed as the code for ESC 3
<10>H.

DLE ENQ n

[Name] Real-time request to printer

[Format] ASCII DLE ENQ n

Hex 10 05 n
Decimal 16 5 n

[Range] n = 0, n = 2

[Description] The printer responds to a request from the host specified by n.

n = 0: Recovers to on-line state.
n = 2: Recovers from an error after clearing the receive and print buffers.

[Notes]

This command should not be used within the data sequence of
another command that consists of two or more bytes. For example,

If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the
host computer) goes to MARK before n is transmitted, and DLE ENQ 2
interrupts before n is received, the code <10>H for DLE ENQ 2 is
processed as the code for ESC 3 <10>H.

This command n = 2 is valid only when a mechanical error or an
auto-cutter error has occurred.

DLE ENQ 2 enables the printer to recover from an error after clearing
the data in the receive buffer and the print buffer.
The printer retains the settings (by ESC !, ESC 3, etc.) in effect when
the error occurred. The printer can be initialized completely by using
this command and ESC @. This command is enabled only for errors
that have the possibility of recovery

ESC & y c1 c2 [x1 d1...d(y x x1)]...[ xk d1... d(y x xk)]

[Name] Define user-defined characters

[Format] ASCII ESC & y c1 c2 [x1 d1...d(y x x1)]...[ xk d1... d(y x xk)]

Hex 1B 26 y c1 c2 [x1 d1...d(y x x1)]...[ xk d1... d(y x xk)]
Decimal 27 38 y c1 c2 [x1 d1...d(y x x1)]...[ xk d1... d(y x xk)]

[Range] y = 2

32 ≤ c1 ≤ c2 ≤ 255
0 ≤ x ≤ 14 (Font A)
0 ≤ x ≤ 12 (Font B)
0 ≤ d1 ... d(y x x) ≤ 255

[Description] Defines user-defined characters.

y specifies the number of bytes in the vertical direction.

c1 specifies the beginning character code for the definition, and c2
specifies the final code. When only one character is desired, use c1 = c2.

x specifies the number of dots in the horizontal direction.

[Notes]

Consecutive character codes for multiple characters can be defined in
one definition. When specifying only one character, specify c1 = c2.

"d" is definition data that indicates the pattern for " x" dots in the horizontal
direction starting from the left edge. If " x" does not satisfy the number of
dots in the character configuration pattern, the remaining dots on the right
are spaces.

The number of bytes required to download a character definition for one
character is " y" x " x".

In the definition data, a "1" represents a dot that is to be printed, and a "0"
represents a dot that is not to be printed.

Independent downloaded character definitions are possible for each font.
The font is selected by the "ESC !" command.

The defined downloaded characters are cleared in the following
circumstances:

1) When "ESC @" is executed

2) When deleted by "ESC ?"

3) When the printer is reset or turned off

[Default] The internal character set

ESC * m nL nH d1...dk

[Name] Select bit-image mode
[Format] ASCII ESC * m nL nH d1...dk

Hex 1B 2A m nL nH d1...dk
Decimal 27 42 m nL nH d1...dk

[Range] m = 0, 1

0 ≤ nL ≤ 255
0 ≤ nH ≤ 3
0 ≤ d ≤ 255

[Description] Selects a bit-image mode using m for the number of dots specified

by nL and nH

Divide the number of dots to be printed by 256. The interger answer is
nH and the remainder is nL. Therefore, the number of dots in the
horizontal direction is calculated by nL + 256 x nH.

If the bit-image data input exceeds the number of dots to be printed on
a line, the excess data is ignored.

d indicates the bit-image data. Set a corresponding bit to 1 to print a dot
or to 0 to not print a dot.

The bit-image modes selectable by m are as follows.

[Notes]

If the values of m and nH are out of the specified range, the following

data is processed as normal data.

After printing a bit image, the printer returns to normal data processing
mode.

The relationship between the image data and the dots to be printed is
as follows.

Hex 1B 44 n1...nk 00
Decimal 27 68 n1...nk 0

[Range] 1 ≤ d ≤ 255

0 ≤ k ≤ 32

[Description] Sets horizontal tab positions.

n specifies the column number (counted from the beginning of the line)
for setting a horizontal tab position.

k indicates the total number of horizontal tab positions to be set.

[Notes]

The tab position is set at [character width x n] from the beginning
of the line. The character width includes the right-side space of the
character, and is twice the normal value when double-width is specified.

This command deletes horizontal tab positions that have already
been set.

When "n = 8" has been set for the horizontal tab position,
the printing position moves to the ninth digit when HT is executed.

Up to 32 tab positions can be set. Data exceeding 32 tab positions
is processed as normal data. Input <n>k in ascending order and place
a NUL code <00>H at the end when <n>k is less than or equal to the
preceding value <n>k-1, tab setting is finished and the following data
is processed as normal data.

ESC D NUL cancels all horizontal tab positions.

The previously specified horizontal tab positions do not change,
even if the character width changes.

[Default] The default tab positions are at intervals of 8 characters

(columns 9, 17, 25, ...) for the font B (12 x 14).

[Description] Turns upside-down printing mode on or off.

When the LSB of n is 0, upside-down printing mode is turned off.

When the LSB of n is 1, upside-down printing mode is turned on.

[Notes]

Only the lowest bit of n is effective.

This command is enabled only when input at the beginning of a line.

In upside-down printing mode, the printer rotates the line to be
printed by 180° and then prints it.

[Default] n = 0

[Notes]

Even if only one of the statuses is enabled, the status is sent when
this command is executed. Subsequently, whenever the state of a
valid status changes, that status is sent. In this case, because the
current state is shown for each status, there is a possibility of a
state change for a status for which ASB is not enabled.

If all statuses are disabled, the Automatic Status Back (ASB)
function is disabled.

When transmitting a status, the printer transmits only four bytes.

Four bytes of status data must be consecutive, except for XOFF code.

This command is executed when the data in the receive buffer is
developed. Therefore, there may be a time lag between receiving
this command and transmitting the status, depending on the
receive buffer status.

When the printer is disabled by ESC = (Select peripheral device),
this command is disabled but ASB is not disabled.

The status to be transmitted are as follows:
