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.

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. Ensure that the Charger is plugged into
a power source which won’t accidently be turned off if you will
be charging batteries overnight.

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 print head 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 print-out and a further
discission on how to use the configuration label as a diagnostic
tool.)
Connecting the Printer
The printer must establish communications with a host terminal
which sends the data to be printed. Communications occur in
four basic ways:
• By a cable between the printer and its host terminal
• Linking to a host terminal via Infrared (usually by means of
the industry standard IrDA protocol)
• By means of a Bluetooth™ short range radio frequency
link.
• By means of a wireless LAN (Local Area Network) per
802.11b specifications.
20 QL 420 User’s Guide
Cable Communications
CAUTION. The power should be turned off before
connecting or disconnecting the communications cable.
All QL 420 printers can communicate by cable; the specific cable supplied with your printer will vary with the host terminal. The
8- pin circular connector on your communications cable plugs
into the serial communications port on the side of the QL 420
printer, which is protected by a weather resistant flap. The connector is keyed to assure correct alignment; do not try to force
the cable if it does not plug in. The other end of the cable must
be plugged into the host terminal as shown in Figure 11, or to a
serial port on a computer (Figure 12.) Communications between
the terminal and the printer are controlled by the applications
running on the terminal and the printer.

IR Communications
Printers equipped for infrared (IR) communications are identified by a small “IR” logo on the unit’s label. IR allows wireless
communications between the printer and the host terminal. IR
units can also communicate with a cable as detailed above, however, IR functions are disabled when the cable is plugged in. QL
420 units with the IR option can be configured to conform to the
standard IrDA communications protocol
Linking a Printer to an IrDA Host
IrDA compliant terminals will automatically initiate communications to the printer. First ensure that there is a direct line of sight
between the printer and the terminal that will be sending data.
The IR window on the front of the QL 420 must face the corresponding window on the terminal to properly send and receive
signals. An IrDA compliant terminal will seek out any linkable devices and establish communications between them, even turning
the printer on if necessary.

Wireless Communications with Bluetooth™using ZBR
Radio
The following section only applies when the Bluetooth Module (FCC ID: I28MD-BTC2-E)
is installed in the QL 420 printer (note that only one of the radio options can be installed in the printer at one time).
“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.
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 Communications with Bluetooth™using ZBR-2
Radio
The following section only applies when the Bluetooth Module (FCC ID: I28MD-BTC2TY)
is installed in the QL 420 printer (note that only one of the radio options can be installed in the printer at one time).
“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.
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.

Bluetooth™ Networking Overview
In order to exchange data, two Bluetooth enabled devices
must establish a connection. Bluetooth software is always running in the background, ready to respond to connection requests.
One device (known as the
connection with another. The second device (the
server
) then accepts or rejects the connection. A Bluetooth en-
master
or the
client)
must request a
slave
or the
abled QL 420 will normally act as a slave, but in theory any Bluetooth device can be either a master or a slave. This miniature
network is sometimes referred to as a “piconet” and can consist
of several Bluetooth enabled devices.
Each Bluetooth QL 420 has a unique Bluetooth Device Address
(BDA) loaded into its QuickLink module when manufactured.
For the most part, communications using the Bluetooth protocol
are initiated and processed without any operator intervention,
much like the IrDA system described previously.

Preventive Maintenance
Extending Battery Life
• Never expose 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.
• Choose the media that is easiest to “burn.” 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 pre-printed label.
• Choose the correct print darkness, and print speed for
your media.
• Use software handshaking (XON/XOFF) whenever possible.
• Select Tear-Off mode whenever possible (Peel-Off mode
uses more power).
• If your printer has the optional LCD display, use the display backlight only when necessary. Turn it off whenever
it is not needed.
• Pull the battery out of the printer if the printer 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.
• Don’t print while the LI 72 Wall Charger is plugged into the
unit. Unreliable battery charging can result.

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 on pg. 40.
2. At the end of 2nd diagnostics report, the printer will print:
“Press FEED key to enter DUMP mode”.
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.
Calling the Help Desk
If the printer fails to print the configuration label, or you encounter problems not covered in the Troubleshooting Guide, contact
the Help Desk. Help Desk addresses and phone numbers for
your area can be found in Appendix D of this manual. The Help
Desk will need the following information:
• Model number/type (e.g. QL 420)
• Unit serial number (Found on the large label on the back
of the printer, also found in the configuration label printout.
Refer to Figures 19 and 19a)
• Product Configuration Code (PCC) (15 digit number found
on the small label on the back of the unit)
