Chapter 1: Outline

The SCP700 Series combines both a quick, quiet and highly reliable thermal
receipt printer with an impact dot slip printer, enabling printing on single or
multiple sheets of slip paper of an unspecified size.

The thermal printer enables receipt printing without a thermal ribbon and makes
paper insertion extremely easy.

The biggest advantage of combining the two printer mechanisms into one unit
is that less space, only one power supply and only one port are necessary,
compared with using a slip printer which is separate from a thermal receipt
printer, each requiring space and a power supply.

Thermal printing on receipt paper is quiet and fast.

For improvement purposes, the descriptions and specifications in this
manual are subject to change without notice.

Chapter 2: DIP Switch Settings

The printer’s DIP switches let you change communications parameters, thermal
printing density, interface type, 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.

❏

Open the printer cover.

❏

Use a Phillips head screwdriver to remove the two screws that secure the

❏

document table in place.

3

Carefully work the document table loose and slide it to the left of the

❏

printer out of the way. It is not necessary to remove the document table
complete, just move it enough so you can get at the DIP switches inside.

❏

After the document table is opened sufficiently, use a thin flat-blade
screwdriver or some other similar object to change DIP switch settings.

❏

Carefully return the document table to its original position and secure it in
place with the two screws.

Available DIP switch settings

There are two DIP switches inside the printer, named DIP Switch 1 and DIP
Switch 2. DIP Switch 1 controls data communication parameters, while DIP
Switch 2 controls other settings.

Buttons

The following table describes the function of the two control buttons of the

Producing a test print

The following procedure can be used at any time to test the receipt printer and
the slip printer.

Turn on the printer and insert a piece of paper into the slip printer. Also

❏

make sure that roll paper is loaded for the receipt printer.

Note:

If you want to produce a test print on the receipt printer only, simply don’t
insert paper into the slip printer.

❏

Turn off printer power.

❏

While holding down the RECEIPT button, turn printer back on. Keep

RECEIPT depressed for a few moments until the printer beeps and the

receipt printer test print starts.
After the receipt test print is complete, the slip printer will produce a test

print on the paper you inserted in the first step of this procedure. The slip
printer test will continue until it reaches the end of the paper.

Press to feed the thermal paper. Holding down this button feeds paper
at high speed.

1. Press this button to release or engage slip paper from the slip
printer. (Switching from releasing to engaging is only possible if
slip paper is inserted.)

2. Press this button to clear the errors of the slip printer and receipt
printer.

Note:

The slip printer momentarily releases the slip paper when you turn printer
power back on. If you are using a lar g e piece of paper, it may fall out of the slip
printer when this happens, causing the slip printer test to be skipped. Because
of this, it is a good idea to keep hold of the paper in the slip printer when you
turn power back on.

Adjusting the slip printer’s 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

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.

Execute the test print

❏

When the slip printer produce the test print, hold down the control panel’s

❏

RECEIPT and SLIP/RESUME buttons, to enter the Dot Alignment

Adjust Mode. The POWER indicator flashes slowly to indicate this mode.

Entering the Dot Alignment Adjust Mode causes seven blocks of characters to
be printed as shown below. An asterisk to the left of the blocks indicates which
setting is currently selected. Use the RECEIPT button to specify which block
has the best aligned characters. Press RECEIPT once to specify the first block,
twice to specify the second block, and so on up to seven times to specify the
seventh block. Pressing the RECEIPT button more than seven times specifies
the seventh block, no matter how many times it is pressed.

Note:

To exit this mode, press the SLIP/RESUME button. The dot alignment adjust
mode setting is stored in the memory, a pattern using the selected setting,
followed by “Adjust Completed” is printed, and the printer ejects the slip paper.

If you press the
after entering the Dot Alignment Adjust Mode, the printer assumes that you do
not want make any settings, so it prints the message “Adjust Complete!” and
exits the mode.
If a paper feed error occurs during this mode, the printer ejects the paper and
this mode is cancelled.

button

Hexadecimal dump

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.

Make sure that roll paper is loaded in the receipt printer.

❏

Turn off the printer.

❏

While holding down the control panel’s SLIP/RESUME button, turn the

❏

printer back on to enter this mode. The printer beeps once to indicate in this
mode.

The printer will now print out the hexadecimal values of any data that is

❏

subsequently sent to it from your computer. The last line buffer should be
flushed by pressing the RECEIPT button.

To exit this mode, turn the printer off.

❏

Errors

There are three types of errors: automatic recovery errors that clear
automatically after some condition is attained, recoverable errors that require
some action by you before they clear, and non-recoverable errors that require
servicing by an authorized dealer. If a slip printer error occurs, the SLIP
indicator flashes quickly. If a receipt printer error occurs, the RECEIPT
indicator flashes quickly.

Data Data Data

Buffer full Buffer empty

Immediately after power on (provided that no error occurs), the printer sets DTR
to “SPACE” to indicate that it is ready to receive data. When the host detects
that DTR is in “SPACE” condition, it begins sending text data over the RXD
line.

When the printer’s remaining buffer space falls to *256 bytes or less, the printer
sets DTR to “MARK.” The host responds by halting the data transfer. However,
note that the printer remains capable of receiving data until the buffer becomes
full.

Available buffer space increases as the printer prints the buffered data. When
the printer has cleared all but the last *256 bytes of data, it sets DTR back to
“SPACE” to indicate that it is ready to receive more data.

Power ON

The output timing conditions for X-ON and X-OFF are set using Memory Switch
4-C. If memory switch 4-C is set to 0 (factory setting), 1 byte is output for the X­ON signal when switching from Off-line (Printer Busy) to On-line (Printer
Ready), while 1 byte is output for the X-OFF signal when switching from On-line
(Printer Ready) to Off-line (Printer Busy). If Memory Switch 4-C is set to 1, the
X-ON signals are output every three seconds.

Immediately after power on (provided that no error occurs), the printer informs
the host that it is ready to receive data by outputting the X-ON signal (control code
DC1; valve = 11H) over the TXD line. If necessary the printer repeats the signal
every three seconds until the host begins sending text data over the RXD line.

When the printer’s remaining buffer space falls to *256 bytes or less, the printer
begins to output X-OFF signals (DC3, value = 13H) over the TXD line. The host
responds by halting the data transfer. Note that the printer remains capable of
receiving data until the buffer becomes full. If Memory Switch 4-C is set to 1,
the X-OFF signal is output each time 1 byte of data is received.

Available buffer space increases as the printer prints the buffered data. When the
printer has cleared all but the last *256 bytes of data, it again outputs the X-ON signal.

(1B)H (6E)H

Select page mode
Switches from line mode (default) to page mode.
This code is only valid when it is entered at the beginning of the line.
The page mode is suitable even though data is printed in the
rotational direction specified by <ESC> “T” n and in the page
coordinate range specified by <ESC> “*” •••, and though paper with
a horizontal length of a check, etc. is rotated 90 or 270 and printing
is carried out in all modes.
In page mode, since OR is applied to the data in the print area,
characters and bit images can be printed overlapping each other and
each character can be rotated and oriented independently.
In page mode, if printing data and a command such as <CR> or
<LF> are sent in the same way as in line mode, there is an automatic
rotation to the printer side.
All printing of data in the print area is performed according to <LF>.
After printing according to <FF>, the printer returns to line mode. In
addition, if <ESC> “!”, <ESC> “@” or <CAN> are specified,
printing is not performed and the printer leaves page mode and
returns to line mode.
While returning to line mode, the data in the printer buffer, the area
coordinates and the rotation directions are all cleared.
This command is only valid with the slip printer.

The following restrictions exist in page mode.

1) In page mode, half-dot characters cannot be printed since
printing is carried out in normal dot units.
When entering page mode, the ANK font is automatically set to
a 5 × 9 (2 pulses = 1 dot) font.
Since the 7 × 9 font and 5 × 9 (3 pulses = 1 dot) font commands
cannot be executed in page mode, they are executed after the
printer returns to line mode.
High density printing of graphics is ignored.

67

2) Paper feed command
In paper mode, the paper feed command and carriage return are
executed in units of dots. A 1/72-inch (0.353-mm) paper feed is
considered 1 dot. Since a 1-dot pitch in the horizontal direction
is 0.30 mm and a 1-dot pitch in the vertical direction is 0.353
mm, the paper amount that is fed while printing using a 90 or
270 rotation is less when compared with a 0 or 150 rotation.
As a result, when printing using a 90 or 270 rotation, execute a
test print, check the horizontal and vertical dot alignment, then
adjust the alignment as necessary.

3) The following commands are not executed in page mode, but
are stored and executed when the printer returns to line mode.

1B 2A XL XH YL YH dXL dXH dYL dYH

Setting print area in page mode
The coordinates of the current position at the moment that page
mode is entered are (0,0). The starting point of the print area is
defined by XL, XH, YL and YH. In addition, the length DX in the X
direction is specified by dXL and dXH, and the length DY in the Y
direction is specified by dYL and dYH.

Current position (0,0)

(X0,Y0)

Paper feed direction

Starting point X

0 = XL + (XH × 256) dots

Starting point Y0 = YL + (YH × 256) dots
Length in horizontal direction DX = dXL + (dXH × 256) dots
Length in vertical direction DY = dYL + (dYH × 256) dots

The values of XL, YL, dXL and dYL are between 0 and 255, and the
values of XH, YH, dXH and dYH are between 0 and 1.
However, dXL = dXH = 0 and dYL = dYH = 0 are not included.
In addition, since the maximum range in the X direction (XO + DX)
is 210 dots and the maximum range in the Y direction (YO + DY) is
720 dots, each parameter should be specified to satisfy these ranges.
When the power is turned on, XL = XH = YL = YH = 0 (XO,YO =
0,0)

dXL = 210, dXH = 0 (DX = 210) and
dYL = 64, dYH = 2 (DY = 576).

This command is stored, even in line mode, and the position at the
time that page mode is entered is used as the standard point (0,0).
Since the bottom of the character is used as the baseline, a minimum
print area of 8 dots are necessary in the character height direction to
print data in the page. (When printing a magnified character height,
the paper must be fed before printing.)

This command is only valid with the slip printer.

Print in page mode (only valid when in page mode)
This command can only activate the slip printer. In page mode, all
page data in the page area is printed, then the printer returns to line
mode. After all the page data is printed, the data in the page, the page
print area and the print direction are all initialized.
In addition, this command has no function in line mode.
