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.

❏
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.

DIP Switch 1
The following table shows all the possible settings for DIP Switch 1. This
switch sets the transmission parameters of the Standard Serial Interface. All
switch settings, except for 1-7 and 1-8, are ON when the printer is shipped from
the factory.
DIP Switch 2
The following table shows all the possible settings for DIP Switch 2. The
factory default setting for this switch is all ON.

Chapter 3: Memory Switch Settings
Each memory switch is a 16-bit word store in EEPROM. For details on the
functions and settings of memory switches, refer to “Chapter 9”.
The table below shows the factory settings for the memory switches.

Chapter 4: Control Panel Operations
The control panel gives you some push-button control over the printer’s receipt
and slip printer operations. It also includes indicator lights, which tell you the
current status of the printer at a glance.
Indicator lights
The following table describes the meaning of indicator lights when it is on, off,
or flashing.
* All indicators flash to indicate a non-recoverable error.

Buttons
The following table describes the function of the two control buttons of the
control panel.
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.
Note:
The slip printer momentarily releases the slip paper when you turn printer
power back on. If you are using a large 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.
Button Description
RECEIPT
Press to feed the thermal paper. Holding down this button feeds paper
at high speed.
SLIP/RESUME
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.
