Introduction
T h e S U RV I VO R ® S S T 2 l a b e l p r i n t e r i s a
high-performance, high speed industrial washdown
direct thermal and optional thermal transfer label
printer. Features include:
• Print speed of up to 8"-12" per second
(203.2mm/sec.).
• Common bar codes are resident in SST2
memory and can be printed with or without
adjacent human readable bar code
interpretations.
• Character fonts can be printed in any one of
four directions and with any one of nine
different font sizes. In addition, a resident
smooth font, called CG Triumvirate®, can be
separately selected and contain 10 different
font sizes. By using font multiplication, font
size expands vertically and horizontally up to
24 times.
• A dot-history control circuit, called SEAQTM
(Sequential Energy Adjustment for Quality),
enhances quality while printing at high
speeds. This circuit monitors the printed data
a n d a u t o m a t i c a l l y a d j u s t s t o p r ov i d e
maximum printhead performance. The 0.0049
inch print element prints high-density bar
codes and characters at a 203 dpi resolution.
In addition, the pixel size can be multiplied by
2 in the horizontal and 3 in the vertical
direction, producing larger formats.
• Connects to most computers and controllers
through either RS-232C or the Centronics®
parallel interface.
•
•
•
•
Optional memory cartridges of up to 4MB
font and 4MB Flash provide storage for fonts,
label formats and graphic images.
Optional Ethernet for network communication.
Software-selectable printhead temperature,
print speed, slew rates and form dimensions
provide the option of storing a wide variety of
parameters, thus eliminating the need for
manual adjustments. This is especially helpful
when using several different types or brands
of label stock, or when switching between
direct thermal printing and thermal transfer
printing.
Configurable for “one up” printing mode.
With the present sensor installed and enabled,
the next label is not printed until the last label
printed has been removed from the printer.
Quantities of one-at-a-time can be selected.
Introduction

2.0
General Maintenance
This section describes procedures for general
maintenance and cleaning of the SST2.
2.1
General Cleaning
During normal operation, media debris may
accumulate around the printer mechanism inside the
printer (see Figure 3-3 on page 6). This debris should
be removed regularly using a soft bristle brush and/or
vacuum cleaner.
2.2
Cleaning the Printhead
Foreign particles can collect on the printhead (see
Figure 3-2 on page 5), causing characters or bar codes
to appear light or faded. This type of problem is
evidenced by a continuous light streak which appears
in the same physical position on each printed line.
This condition should only appear after extensive
printer operation or if poor quality paper has been
used. It is recommended that Rice Lake Weighing
Systems-supplied labels are used to obtain continuous
high quality printing.
Recommended printhead cleaning intervals:
• Due to abrasion and foreign particle deposits,
direct thermal printheads should be cleaned
every 50,000 linear inches (12700m).
• Thermal transfer printheads should be cleaned at
least every 250,000 linear inches.
Printhead cleaning procedure:
1. Turn off and unplug printer from outlet.
2. Open cover. Unlock and raise printhead.
3. Gently wipe underside of printhead burn-line
area using a cotton swab moistened (not
soaked) with isopropyl alcohol. Allow to dry.
4. Lower and lock printhead.
5. Close cover. Plug in and turn on printer.
2
SURVIVOR SST2 Service Manual
2.3
Cleaning the Platen Roller
Use the following steps to clean the platen roller of the
SST2.
1. Turn off and unplug printer from outlet.
2. Open the cover. Unlock and raise the
printhead assembly.
3. Use a clean cotton swab or a lint-free cloth
dampened with isopropyl alcohol to wipe off
all debris from the platen roller. Manually
rotate the roller to clean the entire surface.
Allow to dry.
4. Lower the printhead assembly and lock into
position.
5. Close the cover. Plug in and turn on the
printer.
3.0
Parts Replacement
The following sections outline part replacement
guidelines and procedures, and list replacement parts
for the SURVIVOR® SST2 printer.
3.1
Printhead
The SST2 uses a thin film printhead that dissipates
heat faster than thick film, providing a longer head
life. Printhead warranty is 500,000 linear inches with
an expected life (using thermal transfer printing) of
2,000,000 linear inches.
3.2
Mean Time to Repair (MTTR)
Estimated MTTR the printer is less than 15 minutes. A
number of factors contribute to the ease of service.
Primarily, all electronics including the power supply
are located on a single plug-in circuit board. Most
electronic problems can be isolated and repaired with
a simple board swap.
The printhead is also designed for easy replacement.
One mounting screw and two locator pins eliminate
the mechanical head adjustments required of other
thermal label printers.
3.3
Printhead Replacement
Removal:
1. Turn the printer off and unplug from the
outlet. Open the media cover.
2. Loosen the printhead mounting screw.
Carefully unlatch the printhead assembly and
disconnect the two cables from the printhead.
Replacement:
1. Reconnect the printhead cables.
2. Position the printhead on the printhead
assembly and tighten the printhead mounting
screw.
Caution
Be sure to ground yourself to the
chassis before you remove or install the
printhead. This prevents a static
discharge from your body through the
printhead to the ground.

Communications
Using a data detection process, the interface selection occurs automatically in the printer. At power-up, the
printer begins monitoring the interface ports for activity. When the host transmits data, the printer port detecting
this data is set active and remains active as long as data flow continues. Once the incoming (received) data flow
stops and the host timeout value is exceeded, the detection process is repeated. Should the data flow stop before a
complete label format is received, the format is ignored and must be sent to the printer again.
NOTE: To change an active port immediately, cycle the printer power off and on.
4.1
Parallel Port
The parallel interface has two menu-selectable modes of operation: uni-directional or bi-directional. The
uni-directional mode supports forward channel only communication and requires Centronics® cable with a
36-pin male connector.
The bi-directional mode supports forward and reverse channel IEEE 1284 Compliant communications. Data can
be returned to the host in this mode provided it has compliant hardware, supporting software and is connected to
the printer via an IEEE 1284 Compliant cable with a Centronics 36 pin male connector.
4.2
NIC (Network Interface Card) Adapter
The optional NIC adapter has several menu-selectable modes (see Datamax® Manual, PN 75098). The following
LED indicators on the NIC adapter provide operational information:
• LINK: A green LINK LED indicates a good physical connection to the network.
• ACT: The ACT LED (activity) flashes green or red when the server is ready for use; green indicates
activity for this IP address while red indicates collisions on the network.
• 100: A green 100 LED indicates a 100 BASE-T (100 MB) network connection.
The following buttons are accessible from the back of the printer:
• TEST: Causes an NIC configuration label to print.
• ETHERNET RESET: Resets the NIC adapter.
NOTE: Following initialization, the printer indicates READY. However, the NIC adapter is not ready to receive data until
its boot-up process is completed. Depending upon the NIC adapter configuration, this process may take up to two
minutes to complete.
4.3
Serial Port
The serial interface supports RS-232C and, if equipped, RS-422 communications. The following list of serial
port settings is menu-selectable and must match the host computer’s serial port settings.
• Baud rate (serial communication speed)
• Word length
• Word parity
• Number of stop bits
• Handshaking protocol
In addition to the port settings, the serial interface cable wiring must have specific connections (pin-outs) for
proper data exchange between the host and printer. The different serial cable pin-outs and suggested applications
are shown in Figure 4-1 on page 8.

Communicating to RLWS Indicators
To communicate from an RLWS indicator directly to the SST2, a change to the standard RS-232 output is
required. The indicator must have Smart SerialTM communication or a custom serial format developed.
NOTE: The following sections do not apply to the IQ plus® 310A indicator as it does not feature Smart Serial
communication or custom serial format.
4.4.1
Serial String
To develop the correct serial string, you first need to understand the Datamax® Programming Language (DPL)
serial string. For every piece of information printed, the print format record must consist of the following three
pieces of information:
• A header that is fifteen characters long. The header specifies which font is used and where the data is
printed.
• Data to print.
• Termination character (such as a carriage return).

• If printing graphics, lines, boxes, and human-readable fonts 0 through 8,
these three characters are ignored, but they still must be sent to the printer as
000.
• For human-readable font 9, these three characters must be a number from
001 to 010 to select a font size for the CG triumvirate smooth font. Other
selections are available if downloading from RAM, flash memory modules,
ROM font modules.
• For bar code fonts, these three characters represent a bar code height
number. Numbers ranging from 001 (or 0.01 inch) to 999 (or 9.99 inches).
