Introduction
Thank you for choosing our Zebra QL 420 Mobile Printer. This
rugged printer is sure to become a productive and efficient addition to your workplace thanks to its innovative design. Because
it’s made by Zebra Technologies Corporation, you’re assured of
world-class support for all of your bar code printers, software,
and supplies.
• This user’s guide gives you all the information you’ll need
to operate the QL 420 printer.
• The QL 420 uses the CPL programming language. To create and print labels using the CPL language, refer to the
Mobile Printer Programming Guide (available on our website at:
Label Vista™ label creation program.
• The QL 420 has an optional interpreter for the ZPL II
gramming Language which interprets commands up to X.8
firmware. The printer must be equipped with the optional

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 which indicates the battery is
not fully charged (see “Charging the Battery” below and “Operator Controls”).
Charging the Battery
If you are using the LI 72 single battery charger:
Refer to Figure 3. Your battery charger may look slightly different from the ones illustrated.
1. Install the battery in the printer and 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.
•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.
• Battery Packs may be charged either when installed in the
printer or when removed.
Do not attempt to charge batteries with the LI 72 while
printing. Attempting to print while charging can result in
improperly charged batteries.

If you are using the Quad Charger:
The UCLI72-4 Quad Charger is designed to charge up to four
QL 420 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:
Amber Green Battery Status
On Off Charging
On Flashing 80% charged (O.K. to use)
Off On Completely Charged
Flashing Off Fault
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 QL 420 Batteries:
Battery 80% Charged 2.5 Hrs.
Battery Fully Charged 5 hrs.
These times are for completely discharged batteries.
Battery packs which are only partially discharged will
take less time to reach their charged state. Batteries
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.

4: Q
UAD CHARGER
The UCLI72-4 Quad Charger has a safety feature which
stops charging a battery after six hours regardless of its
charge state.
Battery Safety
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.
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.
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. Insure that the Charger is plugged into
a power source which won’t accidently be turned off if you will
be charging batteries overnight.
QL 420 User’s Guide 11
Loading the Media
You can operate this printer in one of two different modes:
Tear-Off or Peel-Off. Tear-Off mode allows you to tear off each
label (or a strip of labels) after it is printed. In Peel-Off mode, the
backing material is peeled away from the label as it is printed.
After you remove this label, the next one is printed.
Installing the Media
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 latch assembly will flip open automatically
• Pull up on the latch assembly as shown at “2” to unlatch
the Media Cover.
• Rotate the media Cover back as shown at “3”, exposing
the media compartment and the adjustable media supports.

2A. Load the media (continued):
Loading media from an external supply. Refer to Figure 7.
The QL 420 has a loading slot in the rear of the media compartment which allows you to use standard 4” (101.6 mm) wide
fan-fold 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.
• 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 print head.
