RW 420 User Guide
Introduction to the RW 420
Thank you for choosing our Zebra RW 420 Mobile Printer. It
is one of a series of rugged printers that are sure to become
productive and efficient additions to your workplace thanks to
their innovative design. Because the RW 420 is made by Zebra
Technologies, you’re assured of world-class support for all of
your bar code printers, software, and supplies.
• This User’s Guide gives you the information you’ll need to
operate and maintain your RW 420 printer.
• The RW 420 uses the CPCL programming language. To
create and print receipts and labels using the CPCL
language, refer to our Label Vista™ label creation pro
gram or the Mobile Printing Systems CPCL Programming Manual which is available on our Web site at:
http://www.zebra.com/manuals .
• The RW 420 includes interpreters for the ZPL II® programming language (up to Version 30.8.4) and the EPL programming language. Manuals for the ZPL and EPL label
design programming languages are available on our Web
site at: http://www.zebra.com/manuals.
Unpacking and Inspection
Inspect the printer for possible shipping damage:
• Check all exterior surfaces for damage.
• Open the media cover (refer to “Loading the Media” in
the Getting Ready to Print section) and inspect the media
compartment for damage.
In case return shipping is required, save the carton and all
packing material.
Reporting Damage
If you discover shipping damage:
• Immediately notify and file a damage report with the ship
ping company. Zebra Technologies Corporation is not
responsible for any damage incurred during shipment of

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
9
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
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.
The indicators under the battery will allow you to monitor
the charging process per the table below:

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
Battery Fully Charged 5 Hrs.
NOTE: These times are for completely discharged batteries.
Partially discharged Battery Packs will take less time to
reach their charged state. Battery Packs which have reached
80% of their charge capacity may be used, however, it is recommended that you allow the batteries to reach a full charge
to maintain maximum battery life.
The UCLI72-4 Quad Charger’s safety features will stop
charging a battery after six hours regardless of its charge
state.

Loading the Media
The RW 420 printer is designed to print either continuous
(journal) media or label stock.
Loading Media in the RW 420 Printer
1. Open the printer: Refer to Figure 5.
• Press the latch release button on the side of the printer as
shown at “1” below. The media cover will open automatically

Loading Media From An Internal Supply
• Refer to Figure 6. Pull the media supports apart, insert
the roll of media between them, and let the media supports close. Ensure that the media pulls off the core in
the direction shown in Figure 6. The supports will adjust
themselves to the width of the media, and the roll of media should be able to spin freely on the supports.

RW 420 User Guide
Loading Media From An External Supply
Refer to Figure 7. The RW 420 configured with the Ex-
ternal Media option has a loading slot in the rear of the
media compartment allowing you to use standard 4 in.
(101.6 mm) wide fanfold media from an external supply.
The external supply must be designed such that it does
not exert excessive drag as media is fed through the
printer, which could result in distorted printing.
Zebra offers a series of vehicle cradles for the RW 420
(p/ns AK17463-003 and AK17463-004) which incorporate
provisions for installation of an external media supply bin.
• Pull the media supports apart, insert a Media Spacer
(Zebra part number BA16625-1) between them, and let
the media supports close. Insert the media from the
external supply through the rear feed slot, between the
media guides and up through the media compartment as
shown. Make sure the side of the media you will be printing on faces the printhead.
