Flexibility
• The ELF-20’s standard one-
button teach product and label
sensors can be effortlessly
adjusted for various labeling
applications. And, with the
manual position setting, your
labels are placed accurately on
the product, each and every time.
• It’s easytoupgradetheELF-20to
activate hot-foil printer controls.
This integrated feature simplifies
label customization and allows
the hot-foil printer to work in
sync with the labeler to ensure
accurate codeplacement.
• Thanks to the user-friendly
operating interface, changing to
differentlabelingapplicationsfor
various product sizes and types
canbedonesimplyandquickly.
Productivity
• A production preset function
means the machine
automatically stopsoncethe
predetermined quantity of
productshasbeenlabeled.
• Thelabel countfeatureletsyou
precisely track progress at any
point during the productionrun.
• The container/production run
counter lets you see the exact
production numberfor the day.
• The ELF-20 features a battery-free
microprocessor control system
that maintains default settings and
memory even after the machine
sits idle for a long period of time.
Up to five settings can be stored
for future use, so you don’t have
to waste time re-entering the
necessaryinformation.
Accuracy
• The ELF-20’s stepper motor
essentially counts the “steps”
necessary to reach the next
label, ensuring fast, accurate
label delivery.
• The ELF-20’s controls are fully
synchronized, ensuring that all
components run at the same
speed.
Practicality
• The ELF-20 can be easily and
conveniently moved to other
production areas, allowing for
changesinproductionorproducts.
• The ELF-20 is easy to work on
andto adjust, putting everything
you need at your fingertips with
theremovalofjustafewscrews.
• All Pack Leader USA labelers
are made of 304 stainlesssteel
and anodized aluminum. This
extremely durable metal is
speciallytreatedtoguardagainst
rusting and other effects from
harsherenvironments.
Compliance
• AllPackLeaderUSAlabelersare
manufacturedincompliancewith
Good Manufacturing Practices
(GMP) standards and meet the
strict ISO 9001 quality control
procedures. So, you can have
confidence undergoing required
quarterly inspections from
industry complianceauditors.

LABELAPPLICATOR
Follow these instructions to insert the labels into the label applicator.
WITH PRINTER WITHOUT PRINTER
Place the label roll on the supply plate and pass the
labels around the tension roller to control over rotation
of theroll.
Securethelabelsbyaddingtensiontothelabelpress
pad. Thiswillpreventthe labelsfromrunningloosely.
Ifaprinterisinstalled, passthelabelsbetween theprint
head and the print pad of the printer.
It is important for the labels to pass through the forks of
the label sensor and make contact with one side. The
label sensor controls the dispensing ofthe labels.

SENSITIVITY ADJUSTING OF LABEL SENSOR
Remove a label from the backing substrate before the sensor.
Onthe control panel, hold down “LENGTH SET” (Figure 1)
until the backing substrate only is positioned in the sensor
(Figure 2).
On the label sensor, hold down the “NORMAL” button until
the green LEDflashes andthen turns solid (Figure 3).
Again, hold down “LENGTH SET” on the control panel until

OBJECT SENSOR
Theobject sensorisafiber opticinfra-red sensorusetodetect the presence ofbottle onthe labeling zone.If
the sensor is not able to detect a bottle, adjust the intensity of the amplifier until the sensor is able to trigger
the applicator to applya label.
Ifsensormoves too far right, the label will come out too
late and will not be applied to the bottle.
If sensor moves too far left, the label will come out too
early and possibly cause vertical wrinkles.
The proper position of the sensor is to make sure the
labelisdispensedandappliestotheapexofthebottles'
surface.
NOTE: The label position can be controlled through the control panel using the label position function.
