QLn320 Technology
The QLn320 uses several technologies made popular in oth-
er Zebra Mobile Printer product lines.
Smart Battery
The QLn320 battery pack is a high capacity, smart Lithium Ion bat-
tery that contains electronics which allow the printer to monitor its
operating parameters. Among these are the number of charge cycles
it has undergone and its date of manufacture. Using these parameters,
the QLn320’s software can monitor the battery’s condition and alert
the user when to recharge or remove the battery from service.
Operating Temperature Charging Temperature Storage Temperature
-200C to +500C 00C to +400C -250C to +650C
The QLn320 printer will only function properly with genuine Zebra
smart battery packs.
The smart battery’s health has three states: GOOD, REPLACE, and
POOR. The battery health factor determines whether or not the print-
er can operate and what is communicated to the user via the display.
# of Charge Cycles Health Power-up Message
<300 GOOD None
<550 but >/=300 REPLACE “Battery Capacity Diminished-Consider
Replacing” *
>/=550 but <600 REPLACE “Warning-Battery is Past its Useful Life” **
>/=600 POOR “Please Replace Battery Before Proceeding-
Shutting Down” ***
* Warning accompanied by three beeps in rapid succession.
** Warning accompanied by a series of three double beeps in rapid
succession.
*** Warning will ash on and o and be accompanied by beeping at
a rate of once per second. After 30 seconds the printer will shut down.

QLn Series User Guide
Printing Technology
The QLn320 uses the Direct Thermal method to print human read-
ible text, graphics and barcodes. It incorporates a sophisticated print
engine for optimal printing under all operational conditions.
Direct Thermal
Direct thermal printing uses heat to cause a chemical reaction on
specially treated media. This reaction creates a dark mark wherever
a heated element on the printhead comes in contact with the media.
Since the printing elements are arranged very densely at 203 d.p.i.
(dots per inch) horizontal and 200 d.p.i. vertical, highly legible char-
acters and graphic elements may be created a row at a time as the
media is advanced past the printhead. This technology has the ad-
vantage of simplicity, as there is no requirement for consumable sup-
plies such as ink or toner. However, since the media is sensitive to
heat, it will gradually loose legibility over long periods of time, espe-
cially if exposed to environments with relatively high temperatures.

Getting Ready to Print
Battery
Installing the Battery
Important • Batteries are shipped partially charged. Remove
protective shrink-wrap and labels from new battery packs prior to use.
1. Locate the battery compartment on the bottom of the printer.
2. Insert the battery into the printer as shown in Figure 2. (It is not
possible to insert the pack in an incorrect orientation.)
3. Rock the battery into the compartment 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 which indicates the
battery is not fully charged (see “Charging the Battery” below
and “Operator Controls”).
You must charge the batteries fully before using them for
the first time. To ensure maximum battery capacity, new bat-
teries should go through two or three complete charge/dis-
charge cycles when first put into service.

The UCLI72-4 Quad Charger is designed to charge up to four
QLn320 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 5, noting the
orientation of the battery pack. Slide the battery pack into
the charging bay until it stops and then rock the battery
pack back until it snaps into place. The amber indicator di-
rectly under the battery being charged will turn on if the
battery is properly inserted.

Quad Charger Cycle Times :
Battery Status QLn320
Battery 80% Charged 1.5 Hrs.
Battery Fully Charged 3 Hrs.
Note • 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.
The UCLI72-4 Quad Charger has a safety feature which stops charging
a battery after six hours regardless of its charge state. If not fully
charged, it might be indicative of a battery that needs to be replaced.
Battery Safety
Caution • 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 re.
Important • Always refer to the Important Safety Information data
sheet shipped with each printer and the Technical Bulletin shipped
with each battery pack. These documents detail procedures to
ensure maximum reliability and safety while using this printer.
Important • Always dispose of used batteries properly. Refer to
Appendix E for more battery recycling information.
Caution • Use of any charger not approved specically by Zebra for
use with its batteries could cause damage to the battery pack or the
printer and will void the warranty.
Caution • Do not incinerate, disassemble, short circuit, or expose to
temperatures higher than 60oC (140oF).

Bluetooth, and is solid when link is established. This icon
appears only on printers with the Bluetooth wireless op-
tion installed.

radio network via 802.11 protocols. The antenna icon will
blink with no parentheses when looking for an access

The Error icon will be displayed and blink if an error
condition exists. The icon will not be displayed if no print-
er error exists. Since there are separate icons for Media
Out and Head Latch Open, these two alerts do not apply
to the Error icon.
The Battery Charge Level icon indicates the report-
ed state of charge from the battery pack. In a non-charg-
ing state, four (4) bars indicates the battery level is great-
er than 80%. Three (3) bars indicates if the battery level is
less than or equal to 80% but greater than 60%. Two (2)
bars indicates if the level is less than or equal to 60% but
greater than 40%. One (1) bar indicates if the battery level
is less than or equal to 40% but greater than 20%. And
zero (0) bars indicates if the level is less than or equal to
20%.
While the battery is charging, a lightning bolt will appear in the
battery icon to indicate that charging is taking place.
When the battery is charging and fully charged, four bars will be
displayed. When the battery is charging and the level is greater
than 80%, the battery icon will alternate between four bars and
three bars. When the battery is charging and the level is less than
or equal to 80% but greater than 60%, the icon will alternate be-
tween three bars and two bars. When the battery is charging and
the level is less than or equal to 60% but greater than 40%, the
icon will alternate between two bars and one bar. When the bat-
tery is charging and the level is less than or equal to 40% the icon
will alternate between one bar and zero bars.
