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.

RW 420 User Guide
mode. The battery is ready for use.
• 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

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.

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 computer 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)

Wireless Communications
Wireless Communications with Bluetooth®
The following section only applies when the ZBR3 Bluetooth Radio
(FCC ID: I28MD-BTC2TY2) is 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 Blue
tooth 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
-
23
RW 420 User Guide
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.

RW 420 User Guide
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.
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 420 printers
will vary with each WLAN application. General information on
establishing WLAN communications can be found in either the
“Mobile Printing Systems CPCL Programming Manual” or the
“Quick Start Guide for Mobile Wireless Printers.” Both docu
ments are available on-line at:
http://www.zebra.com/manuals
-
More information and WLAN 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 at:
Setting Up the Software
http://www.zebra.com/SD/product _ LabelVista.htm
RW 420 printers use Zebra’s CPCL Programming language
which was designed for mobile printing applications. CPCL
is fully described in the ”Mobile Printing Systems CPCL Programming Manual”, available on-line from Zebra’s Web site at:
http://www.zebra.com/manuals
27
RW 420 User Guide
You can also use Label Vista™, Zebra’s Windows™
based label creation program which uses a graphical in
terface to create and edit labels in the CPCL language.
Label Vista is available on-line from Zebra’s Web site at:
http://www.zebra.com/SD/product _ LabelVista.htm
RW 420 printers also support an interpreter for ZPL II®, or
EPL programming languages. To use ZPL II or EPL, refer to
the appropriate Programming Guides available on-line from
Zebra’s Web site. If you choose to use a third party label prep
aration system, follow the installation instructions included in

The RW 420 can be equipped with optional Magnetic Stripe
and Smart Card readers. The magnetic stripe card reader allows the user to swipe magnetic stripe cards such as credit
cards through a slot in the printer and then read and process
the data contained in the card.
In a similar manner the Smart Card reader can read the in
formation written in the microchip embedded in Smart Cards,
and process the information in the chip in a variety of ways
depending on the printer’s application.

RW 420 User Guide
The MSR is used as follows:
1. When the reader is enabled, place the card into the
reader slot as shown. The magnetic stripe (typically on
the back of the card) must face the bottom of the printer,
and be inserted into the bottom of the card reader slot as
shown in Figure 15.
2. Slide the card through the slot. The card will be read
if slid in either direction. Depending on the application
software, the printer will sound one chime when a scan is
successful .
3. If the card did not read, slide it back through the slot in
the opposite direction.

Smart Card Reader
The optional Smart Card reader is used as follows:
1. The LCD will display “RDR” to indicate the Smart Card
reader is active. (Some reader applications may flash the
display backlight and/or chime three times to indicate the
reader status is “ready.”) At this time, the Printer is acting
only as a Smart Card reader connected to the host terminal; all other printer functions are suspended.
2. Insert the card into the reader slot as shown in Figure 16.
The microchip imbedded in the card must be oriented
facing the bottom of the printer and must be completely
inserted into the Reader Slot to scan successfully .

The RW 420 can be used in conjunction with a docking
Cradle. When the printer is “docked” the Cradle will charge
the printer’s battery and allow the printer to print, receive and
transmit data as usual. The Cradle can provide power from
a 12 VDC power supply either from a power take-off point in
a vehicle or from an external power supply running off A.C.
power. Refer to the documentation supplied with the Cradle
for more information.
Installing the Printer in the Cradle
It is recommended as a safety precaution that the
adjustable shoulder strap be removed prior to docking the
Printer. This precaution ensures the strap will not interfere with
proper operation of the vehicle.
• Remove the Docking Connector Cover from the bottom

Preventive Maintenance
Extending Battery Life
• Avoid exposing the battery to direct sunlight or temperatures over 104° F (40° C).
• Always use a Zebra charger designed specifically for
Lithium-Ion batteries. Use of any other kind of charger
may damage the battery.
• Use the correct media for your printing requirements. An
authorized Zebra re-seller can help you determine the
optimum media for your application.
• If you print the same text or graphic on every label, consider using a preprinted label.
• Choose the correct print darkness, and print speed for
your media.
• Use software handshaking (XON/XOFF) whenever possible.
• If your printer has the optional LCD display, use the display backlight only when necessary. Turn it off whenever
it is not needed.
• Remove the battery from the printer if it won’t be used for
a day or more and you’re not performing a maintenance
charge.
• Consider purchasing an extra battery.
• Remember that any rechargeable battery will lose its
ability to maintain a charge over time. It can only be
recharged a finite number of times before it must be
replaced. Always dispose of used batteries properly.
Refer to Appendix D for more information on proper battery disposal.
• Don’t print while the LI 72 Wall Charger is plugged into
the unit. Unreliable battery charging can result.
