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 fol-
lowing 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 com-
partment.
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 indica-
tors 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 dif-
ferent 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.

10
RW 420 User Guide
mode. The battery is ready for use.
• A rapidly blinking light indicates a problem with the bat-
tery. 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
Note: A fault condition is caused by a problem with the battery.
The charger may indicate a fault because the battery is too
hot or cold to charge reliably. Try to charge the battery again
when it returns to the room’s ambient temperature. If the Amber
indicator starts flashing on the second attempt, the battery
should be discarded.
Quad Charger Cycle Times for RW 420
Battery Status Time
Battery 80% Charged 2.5 Hrs

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 num-
ber, baud rate, etc. The second report prints out more de-
tailed 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 print-
out and a further discussion on how to use the configuration
label as a diagnostic tool.)
21
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.
Figure 11: Communications Port
Cable Communications
Serial (RS232C)
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 termi-
nal. 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 con-
nector, 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.

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 interfer-
ence 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 an-
other. The second device (the slave or the server) then accepts
or rejects the connection. A Bluetooth enabled RW 420 print-
er 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 initi-
ated 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
vices. (USB drivers are included in the Zebra Universal Driver
which can be downloaded from www.zebra.com/drivers.) Other
terminals or communications devices may require the installa-
tion of special drivers to use the USB connection. Consult the
factory for further details.
24
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.

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: http://www.zebra.com/SD/product _ LabelVista.htm
28
RW 420 User Guide
Setting Up the Software
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 Pro-
gramming Manual”, available on-line from Zebra’s Web site at:
http://www.zebra.com/manuals
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 package.

Card Reader Options
The RW 420 can be equipped with optional Magnetic Stripe
and Smart Card readers. The magnetic stripe card reader al-
lows 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.

Cradle
The RW 420 can be used in conjunction with a vehicle
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 is provided power by a
12 VDC power source from a power take-off point in a vehicle.
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
of the printer, and retain it for future use. (Refer to Figure
20.)
• Place the bottom of the printer over the two pins in the
Cradle.
• Rock the top of the Printer into the Cradle and press
firmly until it latches in place.
• Ensure the Cradle power indicator is lit and turn the
printer on.
You can load media (including media from an external sup-
ply) and perform cleaning operations normally when the
RW 420 Printer is installed in the Cradle .
The RW 420 will allow the four display lines on the control
panel to be rotated 180º when the printer is docked. This
allows for easier reading of the display when the Cradle is
mounted vertically. Refer to Figure 19.

Preventive Maintenance
Extending Battery Life
• Avoid exposing the battery to direct sunlight or tempera-
tures 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, con-
sider using a preprinted label.
• Choose the correct print darkness, and print speed for
your media.
• Use software handshaking (XON/XOFF) whenever pos-
sible.
• If your printer has the optional LCD display, use the dis-
play 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 bat-
tery disposal.
• Don’t print while the LI 72 Wall Charger is plugged into
the unit. Unreliable battery charging can result.

erator 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 soft-
ware 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 set-
tings
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.”
43
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 re-
turn the printer to normal operations:
1. Turn the printer OFF.
2. Wait 5 seconds.
