Getting Ready to Print
Battery
Battery Safety
The Battery Packs used on Zebra Mobile Printers contain a
great deal of energy and can cause personal injury or start a
fire if used improperly or carelessly. Please observe the following safety practices:
Avoid accidental short circuiting of any battery. Allowing battery
terminals to contact conductive material will create a short circuit
which could cause burns and other injuries or could start a fire.
Batteries can explode or catch fire if improperly charged or
exposed to high temperatures or fire.
Do not disassemble, crush or expose batteries to water.
CAUTION: Use of any charger not approved specifically by Zebra for use
with its batteries could cause damage to the battery pack or the printer
and will void the warranty.
Installing the Battery
NOTE: Batteries are shipped uncharged. Remove protective shrink-wrap and labels
from new battery packs prior to use.
1. Rotate the Belt Clip to allow access to the Battery compartment.
2. Insert the battery into the printer as shown in Figure 2,
3. Rock the Battery into the printer as shown until it locks in
place.
When the battery is first installed, the Control Panel indicators may briefly turn on and then go off, indicating the battery
is not fully charged (see “Charging the Battery” below and
“Operator Controls.”)
Charging the Battery
Model LI 72 Single Battery Charger
Refer to Figure 3. Your battery charger may look slightly different from the one illustrated.
1. Plug the Charger into the appropriate A.C. wall receptacle.
Then insert the charge cable into the battery charger jack.
2. The charger LED will indicate the status of the charger as
follows:
• A steady light indicates the battery is undergoing a fast
charge.
• A slow blinking light indicates the charger is in trickle
mode. The battery is ready for use.
11
RW 420 User Guide
• A rapidly blinking light indicates a problem with the battery. The battery may have an internal short, or its charge
monitoring circuitry may be malfunctioning. The battery
should not be used any further.
Note: While the LI 72 Charger allows Battery Packs to be charged
when installed in the printer, best results are obtained with the battery
removed.
Do not attempt to print while charging batteries with the LI 72 charger.
Attempting to print while charging can result in improperly charged
batteries.
Model UCLI72-4 Quad Charger
Charger Safety
Use care in locating the Quad Charger. Do not place it in locations
where liquids or metallic objects may be dropped into the charging
bays. Do not block the ventilating slots on the top and bottom covers.
Ensure that the Charger is plugged into a power source which won’t
accidently be turned off if you will be charging batteries overnight.
The UCLI72-4 Quad Charger is designed to charge up to four
RW Series battery packs simultaneously. Batteries must be
removed from the printer to be charged in the Quad Charger.
1. Ensure that the charger has been installed properly per
the Quad Charger instruction manual. Ensure that the power
indicator on the front panel is on.
2. Remove any protective shrink-wrap and labels from all
battery packs prior to use. Plug a battery pack into any one
of the four charging bays as shown in Figure 4, noting the orientation of the battery pack. Slide the battery pack into the
charging bay until it stops. Then rock the battery pack back
until it snaps into place. The amber indicator directly under
the battery being charged will turn on if the battery is properly
inserted.

RW 420 User Guide
Verify the Printer Is Working
Before you connect the printer to your computer or portable
data terminal, make sure that the printer is in proper working
order. You can do this by printing a configuration label using
the “two key reset” method. If you can’t get this label to print,
refer to “Troubleshooting.”
Printing a Configuration Label
1. Turn the printer off. Load the media compartment with
journal media (media with no black bars printed on the
back)
2. Press and hold the Feed Button.
3. Press and release the Power button and keep the Feed
button pressed. When printing starts, release the Feed
button.
The unit will print a line of interlocking “x” characters to
ensure all elements of the printhead are working, print out the
version of software loaded in the printer and then print two reports.
The first report indicates model, ROM version, serial number, baud rate, etc. The second report prints out more detailed information on the printer’s configuration and parameter
settings. If no second report appears, there is no application
loaded. (See the Troubleshooting Section for a sample printout and a further discussion on how to use the configuration
label as a diagnostic tool.)
22
RW 420 User Guide
Connecting the Printer
The printer must establish communications with a host terminal which sends the data to be printed. Communications
occur in three basic ways:
• By a cable between the printer and its host terminal using
either RS232C or USB protocols.
• By means of a Bluetooth short-range radio frequency link.
• By means of a wireless LAN (Local Area Network) per
802.11b specifications.
While the RW 420 can be equipped with both a Bluetooth radio and a 802.11b radio
they cannot be operated concurrently.

CAUTION. The power should be turned off before connecting or
disconnecting the communications cable.
All RW 420 printers can communicate by cable; the specific
cable supplied with your printer will vary with the host terminal. The 10- pin modular connector on your communications
cable plugs into the serial (RS232C) communications port on
the side of the printer. Plug the connector into the RS232C
port and ensure the locking device has clicked into position.
Then press the Locking Plug into the opening around the connector, aligning its locking features with the cutouts on the RW
420 case. Turn the Locking Plug clockwise one-quarter turn to
secure it in place.
The other end of the cable must be plugged into the host
terminal as shown in Figure 12, or to a serial port on a com23

puter as shown in Figure 13. Communications between the
terminal and the printer are controlled by the applications running on the terminal and the printer.
USB
RW 420 Printers also can communicate by cable via the USB
protocol. The USB port is a USB Mini-AB type connector located directly above the 10- pin modular connector used for
RS232C communications. (Refer to Figure 11)
The RW 420 is configured with the USB Open HCI interface
driver allowing it to communicate with Windows® based devices. (USB drivers are included in the Zebra Universal Driver

installed in a RW 420. The antenna used for this transmitter must not be co-located or must not operate in
conjunction with any other antenna.
“Bluetooth” is a worldwide standard for the exchange of
data between two devices via radio frequencies. Bluetooth
radios are relatively low powered to help prevent interference with other devices running at similar radio frequencies.
This limits the range of a Bluetooth device to about 10 meters
(about 32 feet).
Both the printer and the device it communicates with must
follow the Bluetooth standard.
Bluetooth Networking Overview
Bluetooth software is always running in the background,
ready to respond to connection requests. One device (known
as the master or the client) must request a connection with another. The second device (the slave or the server) then accepts
or rejects the connection. A Bluetooth enabled RW 420 printer will normally act as a slave creating a miniature network
with the terminal sometimes referred to as a “piconet.”
For the most part, communications using Bluetooth are initiated and processed without any operator intervention.
Each Bluetooth enabled RW 420 printer has a unique
Bluetooth Device Address (BDA) loaded into its radio module
when manufactured.

Exposure to Radio Frequency Radiation
The radiated output power of this internal Bluetooth radio is far below
the FCC radio frequency exposure limits. Nevertheless, this Bluetooth
radio must be used in such a manner that the antenna is 2.5 cm. or
further from the human body.
The radio and antenna are mounted internally in this printer such that
when the printer is worn with the back of the printer against the body
and the front of the printer (where paper exits) away from the body,
then the 2.5 cm distance between the antenna and the users body will
be met. Do not use the printer in an unauthorized manner.
The internal Bluetooth radio operates within guidelines found in radio
frequency safety standards and recommendations. The level of energy
emitted is far less than the electromagnetic energy emitted by other
wireless devices such as mobile phones.

Wireless Local Area Network Overview
RW 420 printers can be equipped with several radio options
which use the industry standard 802.11b protocol.
• RW 420 printers with a Compact Flash (CF) radio module
can be identified by the FCC ID number “I28MD-RW4137”
and other regulatory information on the serial number label on the back of the unit.
• RW 420 printers with a Zebra 802.11b radio module can
be identified by the FCC ID number “I28MD-ZLAN11B”
and other regulatory information on the serial number label on the back of the unit.
Printers so equipped allow wireless communication as a
node within a Wireless Local Area Network (WLAN) and its
wireless capabilities allow communications from any point
within the WLAN’s perimeter.
Methods of establishing communications to RW series printers will vary with each LAN application. General information
on establishing WLAN communications can be found in either
the ”CPCL Programmers Manual” or the “Quick Start Guide
for Mobile Wireless Printers” both available on-line. More information and LAN configuration utilities may also be found
in Zebra’s Label Vista™ program (version 2.8 and later). Label
Vista may be downloaded from the Zebra Web site.

printer and can be read with the module installed.
WARNING: Use of a RW 420 printer with the radio module marked
with “FCC ID: I28MD-RW4137” meets the FCC requirements for
radio frequency (RF) radiation exposure in the standard body worn
configuration with no minimum separation. In this configuration, which
applies whether the belt clip or shoulder strap is used, the face of the
printer from which paper is transported is facing away from the user’s
body. The standard configuration must always be used when the printer
is body worn.
RW 420 printers with this radio option have been SAR tested. The
maximum SAR value measured for each model was 0.062 W/kg
averaged over 1 gram.

Performing a Forced Shutdown
It the printer has locked up and is not responding to any operator inputs or external commands, from either a connected
terminal or a linked LAN, you can perform a forced shutdown.
• If the printer software locks up during normal operation,
force the printer to shut down by pressing and holding
the Power Button for 3 seconds.
• If you try to turn the printer off normally and the software locks up, the printer will automatically shut itself off
after a 10 second delay.
• If you try to turn the printer off and it does not respond,
you can force an immediate shut down by pressing and
holding the Power Button again within 10 seconds.
A forced shutdown will preserve the printer’s data and settings
Communications Diagnostics
If there’s a problem transferring data between the computer
and the printer, try putting the printer in the Communications
Diagnostics Mode (also referred to as the “DUMP” mode). The
printer will print the ASCII characters and their and their text
representation (or the period ‘.’, if not a printable character) for
any data received from the host computer
To enter Communications Diagnostics Mode:
1. Print a configuration label as described above.
2. At the end of 2nd diagnostics report, the printer will print:
“Press FEED key to enter DUMP mode.”
46
RW 420 User Guide
3. Press the FEED key. The printer will print: “Entering
DUMP mode.”
NOTE: If the FEED key is not pressed within 3 seconds, the printer will print “DUMP mode
not entered” and will resume normal operation.
4. At this point, the printer is in DUMP mode and will print
the ASCII hex codes of any data sent to it, and their text
representation (or “.” if not a printable character).
Additionally, a file with a “.dmp” extension containing the
ASCII information will be created and stored in the printer’s
memory. It can be viewed, “cloned” or deleted using the Label
Vista application. (Refer the Label Vista documentation for
more information.)
To terminate the Communications Diagnostics Mode and return the printer to normal operations:
1. Turn the printer OFF.
2. Wait 5 seconds.
3. Turn the printer ON.
