About this Manual
This manual is intended for use by service technicians responsible for installing SP2200 ticket printers. The
manual is organized based on the procedures you will likely follow when setting up and using your printer.
This manual applies to printers using Version 1.2 of the SP2200 software.
Some procedures described in this manual require removal of the printer covers.
These procedures are to be performed by qualified service personnel only.
1.0 Introduction
The SP2200 Ticket Printer is a bidirectional dot matrix printer designed for use in electronic weighing, point-
of-sale, and industrial applications. The SP2200 is available in 115 VAC, and 230 VAC models.
1.1 Operating Modes
The SP2200 uses two principal operating modes, weight extraction mode and standard input mode, to process
and print the data sent by the host device. These modes are selected using a DIP switch on the back of the
SP2200. A third mode, called monitor mode, is a diagnostic mode associated with the printer self-test func-
tion.
1.1.1 Weight Extraction Mode
Weight extraction mode is used to extract weight information from the serial outputs of weighing devices.
Used in weight extraction mode, the SP2200 extracts weight, units, and status information from the scale
output and sends the data to the printer buffer in the format shown below. Note: The format of the printed
output depends on the SP2200 configuration.
WWWWWWW UU HH:MM xM MM/DD/YY CCCCCCCC
where:
•WWWWWWW is the weight
•UU is the units (lb or kg)
•HH:MM xM is the time (If US format is used, xM is the am/pm indicator. If international format is
used, time is shown as HH:MM using a 24-hour clock.)
•MM/DD/YY is the date (If US format is used. If international format is used, the date is shown in the
format DD/MM/YY.)
•CCCCCCCC is the ID code
The SP2200 must be configured for weight extraction mode when connected to devices sending data as
continuous output.
1.1.2 Standard Input Mode
Standard input mode is used to print data exactly as received from the sending device. In standard input mode,
the host device controls the content and formatting of the information printed.

1.1.3 Self-Test and Monitor Mode
The self-test function and monitor mode are used to test the SP2200 and installed options. The self-test
function provides a dot firing test, an ASCII character dump routine, and a list of installed options and DIP
switch settings. Monitor mode is a test state entered once the self-test is complete. In monitor mode, the
SP2200 prints characters and control codes sent to it without interpreting the data.
See Section 2.3 for more information about using the SP2200 self-test and monitor mode.
1.2 Optional Equipment
The following sections describe optional equipment available for the SP2200 ticket printer. If you ordered
your printer with one or more of the options listed below, the option was installed at the factory. For informa-
tion about installing the options, see Section 2.4, Installing Optional Equipment.
1.2.1 20mA Current Loop Interface
The 20mA current loop interface is a current-based serial interface, capable of data rates of 300 to 19200 bits
per second over a cable length of up to 1000 feet (300 meters). The 20mA interface is used to connect the
SP2200 printer to host devices using that interface rather than the standard RS-232C interface.
1.2.2 RS-422A Interface
The RS-422A interface is a differential voltage-based serial interface capable of transmitting data over
distances of up to 4000 feet (1200 meters) at data rates of up to 10 Mbps. RS-422 can be configured for multi-
drop communications with as many as ten receivers.
1.2.3 Parallel Interface
The parallel interface option is used to connect the SP2200 printer to host devices with parallel data ports.
Many personal computers and ASCII terminals use parallel ports for printer connection.
1.2.4 Switch Module
The switch module option provides the SP2200 printer with a number of capabilities that may be required for
some applications. The switch module option lets you:
• Enter ID codes to be printed with weight information
• Set time and date without an attached serial sending device (requires time and date module)
• Request printing using the PRINT button on the SP2200 switch module
1.2.5 Time and Date
The time and date option provides time and date stamping for tickets printed by the SP2200. The time and
date module can be programmed using the optional switch module or a serial sending device.
1.3 Front Panel Indicators
The three LEDs on the front panel of the SP2200 are used as follows:
POWER (green LED) Indicates that the printer is connected to a power source and the rear panel
power switch is on.
FORM OUT (red LED) Indicates that there is no ticket in the printer. This indicator is active only if
the paper sensor is set on. See Section 4.3.7 for more information.
FAULT (amber LED) Indicates that the time and date or ID code information being entered is either
incomplete or invalid. The FAULT LED is normally lit when using the
switch module to enter this information. When the entry is complete, the
LED turns off.

2.0 Installation and Setup
2.1 Unpacking and Inspecting
Immediately after unpacking, perform a visual inspection of the SP2200. Notify the shipper and Rice Lake
Weighing Systems immediately if any damage occurred during transportation.
Replace all packing materials, including the plastic bag and the cardboard insert, in the shipping carton. Store
the carton in a safe place so that it will available if the printer is relocated or returned for service.
Factory installation of some printer options, such as the switch module and the parallel interface, can be
verified by visual inspection. For other options, such as the time and date module and the 20mA current loop
interface, use the self-test procedure described in Section 2.3 to verify installation.
2.2 Setup
Initial setup of the SP2200 consists of installing the print ribbon, setting the head gap, and running the printer
self-test. See Section 2.4 for information about installing optional equipment.
Before connecting the printer to a power source, check the operating voltage shown on the back panel of the
printer. Verify that the source voltage is within the operating range of the printer.
2.2.1 Installing the Print Ribbon
Use the following procedure to install print ribbon cartridges:
1. Turn off the printer. Open the print mechanism cover.
2. Use a pencil to pull a few extra inches of ribbon out of the ribbon cartridge (see Figure 2-1).
Figure 2-1. Use a pencil to pull extra ribbon from the cartridge before installing

3. Snap the cartridge into place, fitting the hole in the ribbon take-up knob over the ribbon drive gear. If
necessary, adjust the ribbon take-up knob to align the cartridge gear with the ribbon drive gear.
4. Use a pencil to loop the ribbon over the left ribbon guide (see Figure 2-3).
5. Thread the ribbon between the ribbon deflector and the printhead.
6. Loop the ribbon over the right ribbon guide.

7. Turn the cartridge knob to take up slack in the ribbon.
8. Slide the printhead back and forth several times to ensure that the ribbon is being fed as the printhead
moves.
9. Switch printer power on.

2.2.2 Setting the Head Gap
The SP2200 is designed to accept forms up to a thickness of .024 inches (0.609 mm). The head gap adjust-
ment lever (Figure 2-4) can be set to print up to 5-part forms. The six detents allow a head gap range of .004
to .024 inches in .004-inch increments. Move the adjustment lever toward the back of the printer to increase
the head gap.
Figure 2-4. Head gap adjustment lever, located on left side of the print mechanism
2.3 Printer Self-Test
The SP2200 self-test function is used to verify the operation of the printer. The self test should be run before
using the printer when first installed and after installing any optional equipment. The SP2200 self-test pro-
vides the following information:
• Software revision number
• Dot firing test
• Printout of ASCII character set
• Configured baud rate
• List of installed options
• DIP switch settings
Figure 2-5 shows an example of a ticket printed using the SP2200
self test.
Figure 2-5. Printer self-test ticket

2.3.1 Self-Test Procedure
To run the SP2200 self-test, do the following:
1. Turn off the printer.
2. Set DIP switch 3-7 on. This switch puts the printer in self-test/monitor mode.
3. Insert a form into the printer.
4. Turn on the printer to print the self-test information.
To test the serial port, you must use a test plug for the loop-back test. Running the self-test with a test plug
connected to the serial port checks the configured baud rate and verifies that serial communications is opera-
tional. When the serial port is configured correctly, the self-test ticket includes the statement SERIAL BAUD
RATE CHECKS GOOD (see Figure 2-5); if the port is incorrectly configured, the ticket reads SERIAL BAUD
RATE IS HUNG.
A test plug can be easily fabricated using a male DB-25 connector. Figures 2-6a, 2-6b, and 2-6c show test
plugs for RS-232, 20mA current loop, and RS-422A interfaces.
Notes:
1. You must use a separate test plug for each of the interfaces used by the SP2200. A test plug wired for
both RS-232 and 20mA current loop will not verify operation of the 20mA circuit.
2. RS-232 communications is disabled if either of the other serial communications options is installed.
See Section 2.4 for instructions on installing or removing communications options.
2.3.2 Using Monitor Mode
Once the printer self-test has run, the SP2200 goes into a diagnostic state called monitor mode. In monitor
mode, the SP2200 prints any data sent to it without interpreting the data. The SP2200 remains in monitor
mode until DIP switch 3-7 is turned off and the printer is turned off and on again.
You can use monitor mode to determine exactly what information is being sent to the SP2200 by the indicator
or other host device. The full ASCII character set, including the SP2200 control codes (ASCII values 0–31
decimal, 0–1F hexadecimal), are printed without formatting.
Control codes are shown with a caret (^) symbol followed by a second ASCII character that indicates the
specific control code. For example, a carriage return (ASCII value CR, 13 decimal, 0D hex) is shown as ^M; a
line feed (ASCII value LF, 10 decimal, 0A hex) is shown as ^J. See Sections 5.0 and 5.1 for more informa-
tion and a complete list of SP2200 control codes.
