Chapter 1: DIP Switch Settings
The printer’s DIP switches let you change communications parameters, input
buffer size, and emulation. This chapter explains the settings you can make and
tells you how to actually change DIP switch settings.
Accessing the DIP switches
The DIP switches are located inside the printer, underneath the document table.
Use the following procedure to remove the document table so you can operate
the DIP switches.
Make sure that the printer is turned off and unplugged from its wall outlet.
❏
Remove the printer cover.
❏
While using a screwdriver or other similar instrument to press down at the
❏
location marked (a) in the illustration below, carefully slide the document
table in the direction indicated by the arrow until it is out of the way.

If the document table seems to be getting caught on the rollers, it means that
you are not pressing down at point (a) enough. Pressing at point (a) should
separate the rollers to the document table can slide freely.
❏
After the document table is opened sufficiently, use a thin flat-blade
screwdriver or some other similar object to change DIP switch settings.
See the following section for details on available DIP switch settings.
After making the settings you want, slide the document table back into
❏
place while pressing down at point (a). Make sure that the document table
is correctly seated in place before releasing point (a).
❏
Replace the printer cover.

Feeds the slip paper back, toward the front of the printer. One press
feeds one line, holding down performs continuous feed.
Activates the printer's paper release (the paper is not held in place by
the paper feed roller).
Clears recoverable errors.
Producing a test print
The following procedure can be used at any time to test the printer.
Turn on the printer and insert a piece of paper (page 6, 11).
❏
Turn off printer power.
❏
While holding down RELEASE , turn printer back on. Keep RELEASE
❏
depressed for a few moments until the printer beeps and the printer test
print starts.
The printer test will continue until it reaches the end of the paper.
Adjusting the dot alignment
You may never have to use the procedure described in this section, but after you
have been using your printer for some time you may find that the dots of some
graphics do not align correctly. For example, what should look like:
may come out looking like one of the following:
or like this
8
This is caused when mechanical parts of the printer get out of alignment. This
happens only rarely and you may never experience it at all throughout the life
of the printer. If you do have problems, use the following procedure to correct it.
Turn on the printer and insert a piece of paper.
❏
Turn off printer power.
❏
While holding down the control panel’s FORWARD and REVERSE
❏
buttons, turn the printer back on to enter the Dot Alignment Adjust Mode,
which is indicator by a flashing POWER indicator flashes.
Entering the Dot Alignment Adjust Mode causes seven blocks to be printed,
each of which indicates a dot alignment setting, as shown below. An asterisk
to the left of the blocks indicates which block is currently selected.
Use FORWARD to specify the block that appears to have the best aligned
❏
characters. Press FORWARD once to specify the first block, twice to
specify the second block, and so on up to seven times to specify the sev enth
block.
Warning beep will sound if you press FORWARD more than seven times.
❏
After specifying a block, press REVERSE to register your selection and
exit the Dot Alignment Adjust Mode.
The dots alignment adjustment setting you selected is stored in printer memory
and a pattern is printed using the selected setting followed by the message
“Adjust Complete!” The printer ejects the paper after printing is complete.
Note:
You setting is not registered if you turn off printer power before pressing
REVERSE to exit the Dot Alignment Adjust Mode.
If a paper feed error occurs during this mode, the printer ejects the paper and
this mode is cancelled.
Hexadecimal dump
9
Note:
This procedure prints in hexadecimal format all codes (character codes and
control codes) that are sent to the printer by the computer. The printer does not
execute any control codes (such as 0A - linefeed), it just prints them out. The
hexadecimal dump is useful when you are writing programs for printer control.
❏
Turn on the printer and insert a piece of paper.
❏
Turn off printer power.
❏
While holding down the control panel’s FORWARD buttons, turn the
printer back on to enter the Hex Dump Mode.
❏
To exit the Hex Dump Mode, turn the printer off.
The printer will not responde to any commands you send it while it is in the
Hex Dump Mode.

Errors
There are three types of errors: recoverable errors that require some action by
you before they clear, non-recoverable errors that require servicing by an
authorized service provider, and a data receive error. Errors are indicated by and
audible buzzer and the indicators.

Data protocol
Outline of DTR/DSR mode operations
❏
This communication mode is set when dip switches 1 to 6 are set at ON.
The DTR signal shakes hands with the DSR signal (DSR signal: ESC/POS
mode only) and performs communications. The DTR signal is assumed as the
BUSY signal and then the control for the printer’s data receiving operations
are carreied out, and a “space” means that the printer is to receive the data, and
a “mark” means that the printer is not to receive the data.
RXD
DTR
Printing
Power ON
Data Data Data
Buffer full Buffer empty
The DTR signal line is set a “space” when the power supply is switched on and
no error occurs with the printer. The host confirms that the DTR signal line is
set at “space”, and then transmits the text data to the RXD signal line.
The printer sets the DTR signal line at “mark” when the empty area in the data
buffer is less that the prescribed number of bytes (*1: nearly full buffer
condition.) The host confirms that the DTR signal line is set at “mark” and
suspends text data transmission, but it is possible for the printer to continue
receiving data for the amount of space remaining in the data buffer’s empty area
at this point. If the DTR signal is ignored and data transmitted, the data that
exceeds the amount of space available in the empty area will be discarded. The
empty area in the data buffer will increase as printing is carried out, and the
DTR signal line will be set at “space” if the amount of empty space in the data
buffer is more than the prescribed number of bytes (*2: near empty condition.)
In addition to this, the host will confirm that receiving is possible (DSR signal
= “space”) and transmit the data only when memory switches 4 and 5 are set
at 0 during printer status transmission in the ESC/POS mode’s DTR/DSR
communication mode. (With the exception of certain status transmission
commands. Also, dip switches 1 to 9 must be at OFF when the DSR signal is
confirmed.)
*1 Refer to the nearly full buffer conditions for details on nearly full buffer conditions.
*2 Refer to the nearly empty buffer conditions for details on nearly empty buffer
conditions.

❏ Outline of X-ON/X-OFF mode operations
This communication mode is set when dip switches 1 to 6 are set at OFF.
This mode notifies the host of X-0N (DC1) data when receiving is possible
and X-OFF (DC3) data when printing is not possible with the TXD signal.
The timing conditions for the output of X-ON and X-ON in the STAR mode
are set with the 4-C memory switch. When memory switch 4-C = 0 (set when
the unit is shipped from the factory,) only one byte is output by X-ON during
fluctuations from on-line (printer BUSY) to on-line (printer READY), and
only one byte is output by X-OFF during fluctuations from on-line (printer
READY) to on-line (printer BUSY). The same functions as above occur when
in the ESC/POS mode regardless of the 4-C memory switch setting.
When memory switch 4-C = 1, X-ON is output at regular three-second
intervals.
X–ON X–OFF X–ON X–OFF X–ON
TXD
RXD
Printing
Data Data Data
X-ON (DC1 with the control code name and 11H with hexadecimal display)
is output by the TXD signal line when the power supply is switched on and no
error occurs with the printer. The text data is transmitted to the RSD signal line
after the host has received X-ON.
X-OFF (DC3, 13H) is output when the empty area in the data buffer is less that
the prescribed number of bytes (*1: nearly full buffer condition.) Also, if
memory switch 4-C = 1, X-OFF is output for every byte of data received. The
host that receives X-OFF suspends text data transmission, but it is possible for
the printer to continue receiving data for the amount of space remaining in the
data buffer’s empty area at this point. If data that exceeds the amount of space
available in the empty area is transmitted, it will be discarded.
The empty area in the data buffer will increase as printing is carried out, and X-
ON is output if the amount of empty space in the data buffer is more than the
prescribed number of bytes (*2: near empty condition.)

Signals when data is ready to be read. Signal goes from HIGH to LOW (for at
least 0.5 microsec.) when the data is available.
These signals provide the information of the first to eighth bits of parallel data.
Each signal is at HIGH level for a logical 1 and at a LOW level for a logical 0.
When this signal goes to LOW, the printer is ready to accept data. When the
printer is in one of the conditions below, “HIGH” is set.
1. Data is being entered
2. Off line
3. Error condition
This signal indicates the status of the paper sensor.
[In Star mode]
This signal goes to HIGH when either the TOF or the BOF sensor detects that
there is no paper. The signal will go to LOW when both the TOF and BOF
sensor detect that there is paper installed.
[In the ESC/POS mode]
This signal outputs the status of the sensor selected using the <ESC> “c3”
command.

This becomes a reset signal when DIP switch 1 is set to ON. (See page 4 for
details.) When this signal goes to LOW (for at least 0.5 microsec.), the printer is
reset to its power-on condition.
This signal is normally HIGH. This signal goes to LOW to signal that the printer
cannot print due to an error condition.
