PLU Pricing Modes
PLU Pricing Modes
11BBy-Weight PLU
PLU is an abbreviation for Price Look Up. The PLU is a reference number assigned to a
product's record including fields such as the description, price, tare, etc.
Different PLU's will have different pricing modes. Meat is normally sold "By Weight" by
the pound or kilogram. Many bakery products are sold "By Count". Other products may
be sold in a standard package that all weigh the same (or assumes all weight is the
same or a minimum value). The different pricing modes are as follows –
Examples of products sold By Weight are meats, cheese, poultry, and produce. ByWeight items can be priced in three ways:
Priced "Per Pound/kilo" - Typically weighed items are priced per pound. The weight
multiplied by the unit price equals the total price of the product.
Priced "Per Fraction of a Pound/100g" (fractional) - The item may also be priced
by the fraction of the pound (where legal and desired). Pricing per 1/4 pound and
per 1/2 pound are available. Kilos are not interchangeable for pounds in this
mode.
12BBy-Count PLU
13BStandard Pack PLU
"Pounds/kilos for price" - The PLU may be sold with a pounds-for-price (rather
than price per pound). For example, “2 pounds for $1.00” rather than
“$0.50/pound.”
Examples of items sold by the count are cookies, donuts, rolls, bread, etc. Example: 4
Apples for $0.69. The By-Count PLU allows the operator to use the scale to print labels.
Pricing is entered as a certain quantity of items for a set price. If the total weight for the
items is needed, a weight field can be configured on the label to print the weight of the
items in addition to the By-Count information.
Examples of items sold by Standard Pack include whole chickens, sheet cakes, bread,
etc. The Standard Pack PLU is similar to By-Count and also allows the operator to print
labels. These labels indicate the net weight and total price of the item. These types of
items all weigh the same (or are assumed to weigh the same or of a minimum value).

PLU Screens
The PLU screen will vary based on the type of PLU that is being displayed: By Weight,
By Count or Standard Pack.
On the PLU screen, if a value field has a border it can be changed for that transaction.
Override the values by touching the box and selecting/entering new values. Note: this is
only a temporary override for this transaction only and the values will revert to the
original the next time the PLU is called.
If the field has no border the value cannot be changed, as determined by Setup

Calling Up PLUs
Calling Up PLUs
When the Impact S® is in Service Mode, the operator screen will display the active
department’s Preset Pages and Preset PLUs.
Note: “Service Mode” is normally the default on the PLU Edit screen. After the product
has been weighed, a label has been printed, and the item has been removed from the
scale, the PLU will clear and the scale will return to the home screen, ready for the next
item.
To begin a transaction, place the item on the weighing tray (can be done after a PLU is
called up).
Call up the PLU (Price Look Up) Record. To do this, find the Preset PLU related to the
product, it may be a By Weight, By Count or Standard Pack item(s). You may also
directly enter the PLU number in order to bring a particular PLU’s data to the screen.
Note: Remember some PLU buttons can link into another page of related items, so you
may need to drill down to find your item’s PLU. Or check that the scale is displaying the
right Preset Page or category for desired PLU. These Preset Page buttons are along the
bottom of the screen and represent PLUs grouped into categories or departments. The
current Preset Page shows a black button, along the bottom. Switch Preset Pages by
touching the desired button.
Once you locate the PLU button touch it to get a detailed PLU screen. The screen will
vary slightly in appearance depending on whether it is By Weight, By Count or Standard
Pack.
Depending on how the PLU has been set up you may be able to edit some of the values
for this current selection. If allowed change items such as Shelf Life, Tare, etc by using a
Temporary Override (see this chapter’s Temporary Override section for details).

Temporary Overrides
Chapter 2: Operating Instructions
Temporary Overrides
Temporary Overrides are certain values can be adjusted for the current transaction only
from within the PLU screen. The changes are temporary and will not be retained in the
original PLU.
If a value can be changed a button will appear around the value. This indicates that the
value can be changed during a transaction.
In the PLU screen above, the Unit Price ($/lb), Tare, Mode, Pack Date, and Shelf Life,
have buttons, indicating they can be changed. The Total Price field does not have a
button and cannot be changed. There is also a button graphic around the Touch to Zero
field, but that does not indicate a changeable field, but rather an interactive one.
To change a value, touch the field. Then depending on the field: enter a numeric value
in the pop-up window using the keypad, toggling to a different within the selected field,
or if there are multiple choices, a new screen will appear and a selection can be made
from that screen.
As always, additional overrides can be found by pressing the OPER button on the
keypad.

Memory Mode
Memory Mode
When the user processes a Memory Mode transaction, he presses the MEM key instead
of the Print key. This will store the transaction data into Memory Mode and return the
user to the Home screen.
If a PLU is added to MEMORY that already exists in MEMORY, it is treated as a separate
entry. This means that it is possible to have multiple transactions associated with the
same PLU.
Making use of items stored via Memory function is simple. Begin with the scale at the
home screen and press the MEM key to bring up a dedicated MEM array. The user will
find Subtotal, RemoveItem and ClearMEM keys available.
In order to make use of data, the user will need to press the Subtotal key. From there,
they will select their MEM entry and press Print when ready.
NOTE: When a PLU is added to MEMORY, the word MEM will display on the main
screen alerting the operator to the presence of data in the MEMORY queue.

you would like to set up on-scale security features.
Most of the functionality of the Security menu exists within the first of the two buttons.
After making any changes, remember to press the Enter key to save.
Users – visit this button to add or edit the specifics of various user profiles. There are
four levels of user than can be defined:
1.) Operator – has access to transaction screens only. No permission to access
setup menu when security is enabled
2.) Supervisor – has access to transactions and item database setup menus.
No permission to access weights and measures significant parameters.
3.) Manager – has access to all supervisor-class screens/menus as well as
scale setup menus.
4.) Technician – has access to all screens, including full setup and calibration
menus.
Security – this field is a toggle that switches between “Enabled” and “Disabled” for the
scale. Only Managers and Technicians can change this state.
Users may take advantage of/edit/create at any level of the system that is equal to or
lower than their own. For example, a Technician can modify anything a Manager,
Supervisor or normal Operator can, but a Supervisor may only modify his own set of

Label Requirements
Label Paper
The purpose of this section is to specify the requirements of thermal labels to be used in
Mettler Toledo retail scale and pre-pack thermal printers.
This document includes dimensional requirements for labels and label rolls, as well as
general requirements for label paper, thermal coatings, preprinting inks and adhesives.
Use of label materials and designs which meet with these requirements is necessary to
ensure operation of the printers in compliance with their respective functional specifications
and satisfactory performance of the label in the end-use environment. Labels which do not
comply with all of the requirements of this document may function with limitations, but
would need to be tested by the customer to insure adequate performance in their
application. Customer specified (COD) software is not covered under this specification.
DESCRIPTION, PRICE LABEL: Premium white color, black imaging, with protective
coating
DESCRIPTION, DAY-GLO LABEL: Red orange fluorescent, black imaging, with protective
coating
• HIGH SPEED: Initial 66°C (151°F); Optimum 77°C (170°F) – for highest
speed printing
•HOT BOX: Initial 83°C (181°F); Optimum 91°C (195°F) - for use on food
items which are kept warm
SURFACE SMOOTHNESS: The surface of the finished coated paper must be smooth to
prevent premature printhead failure. Smoothness must be 40 Sheffield units or
smoother.
ION CONTENT: Ions such as sodium (Na) and chlorine (Cl) can cause premature failure
of the glass overcoat of a thermal printhead. Paper manufactured specifically for thermal
printing with low ion content must be used.
STORAGE LIFE: 18 months minimum when stored at less than 85% relative humidity
and less than 35°C (95°F).
Label must adhere to product with a surface temperature of -15° C (5° F) minimum.
Bond strength must remain permanent over a temperature range of 2°C to 35°C (35°F
to 95° F).

RELEASE LINER
DESCRIPTION: White semi-bleached supercalendered Kraft paper with silicone release
coating
BASIS WEIGHT: 68 ± 3 gram/square meter
THICKNESS: 67 ± 7 μ METER (0.0026 INCH)
TOTAL THICKNESS LABEL + ADHESIVE + LINER
159 ± 17 μ METER (0.0056 to 0.0069 inch)
LIGHT TRANSMISSION FOR GAP SENSOR OPERATION:
(SEE OPTICAL DENSITY DEFINITION)
Light transmission at a wavelength of 800 to 900 NM through the liner ONLY must be
at least three times the transmission through the liner and label together. This means
that the transmission optical density of the liner must be at least 0.48 less than the that
of the liner and label together
Light transmission at 800 to 900 NM wave length through the liner and label together
must be at least 2% of incident light. This corresponds to an optical density of 1.7.
Label Stripping
Finished Label Roll
Requirements
Labels must strip from the liner over a temperature range of 2°C (26°F) at 50% RH to
43°C (110°F) at 85% RH.
CORE AND METHOD OF LABEL ATTACHMENT
The label stock must not be permanently attached to the cardboard core. The liner must
separate cleanly from the core with 1.0 pound pull tangent to the core as shown in Figure
1. No core material, tape, or adhesive is to remain on the label or liner after separation.
Material, especially hot-melt adhesive, remaining on the label can damage the printhead.

Preprinted Labels
Chapter 4: Labels
Preprinted Labels
To ensure trouble free operation of the printer gap sensor, and to achieve normal print
head life, no pre printing should be placed on the label in the gap sensor path or in
areas which will be printed by the scale printer. See Figure 7. However, since
preprinting is commonly used by many customers the following guidelines must be
followed.
1. Inks used for preprinting must be specially formulated for use in thermal printers. If
proper inks are not used they can adhere to the print head. This ink build up on the
print head will interfere with heat transfer from the print head to the paper and cause
printing elements to burn out. Another problem with inks not formulated for thermal
printing is that they can contain chemicals which will cause the glass overcoat to chip
off of the print head, causing failure to print in the chipped areas.
2. If black ink is used in preprinting in the gap sensor path shown in Figure 7, a dense
black stripe will have to be printed on the back of the liner, as shown in Figure 8, to
prevent the gap sensor from being affected by the black preprinting. (Colors other than
black might also be a problem and should be tested by the customer) The black stripe
must have gaps which correspond to the label gaps. The black stripe on the liner must
have a minimum transmission optical density of 2.3 and must be uniform. (see optical
density – page 8) In addition, the gap sensor circuit will need to be adjusted for
operation with the black stripe as explained in the product service manual. This
adjustment will need to be checked any time label paper is changed, for example when
labels are procured from a new supplier.
3. If an optical density of at least 2.3 cannot be achieved in the black stripe on the
back of the liner, the liner width should be increased (as shown in Figure 9) so that the
preprinted label is not in the gap sensor path. For the Impact S, the sensor path in the
center of the label must be free of black preprinting.

Special Shaped Labels
Some examples of oddly-shaped labels
that will require the black stripe for
optical measure.
Labels with shapes other than rectangular will cause gap detection errors if the gap
dimension (in the gap sensor path) is outside the limits given in this document, or if the
edge of the label shape crosses into and out of the sensor path as shown below. For
these cases the black stripe will have to be printed on the back of the liner as shown
previously. Tests will be needed to determine if the stripe will be adequate or if
additional liner width will be required. The safe approach is to use the black stripe
configuration shown previously on all odd shaped labels.
Optical Densities
Definition of Transmission of Optical Density
Transmission optical density is defined as:
Optical Density = log
transmission)
Transmission optical density can be measured with a transmission densitometer that
meets ANSI standards. Examples are the Macbeth model TD903 and TD932.
If liner paper transmits 2% of the light which is incident on it, the optical density is log10
(100/2) = 1.7
If the light transmitted through the liner is 3 times the light transmitted through the liner
and label, the relative optical densities are:
Black Stripe Optical

Optical Density of Liner + Label = log
Optical Density of Liner Only = log

10
(0.3333X)
10
0.3333 + log10 (X)
10
(X) – 0.48
10
Therefore, if the liner must transmit 3 times the light that the liner and label transmits,
the transmission optical density of the liner must be 0.48 less than the transmission
optical density of the liner and label.
If only 0.5 % of incident light is transmitted through the black stripe, the optical density
is:
log
(100 / 0.5) = log10 (200) = 2.3
10
The purpose of specifying a transmission optical density of at least 2.3 for the printed
black stripe on the back of the label is to minimize any variation in light transmission as
a result of black pre-printing on the front of the label. This variation due to black
preprinting can cause the gap sensor to give gap detection errors.

Chapter 5: Maintenance
Printer Cleaning
When doing regular maintenance, or when changing a label roll, check for any buildup
on the Printer Roller (located under the tear strip).
When the printer is pulled out and before the new label roll is installed, rotate the labels.
And then use the Cleaning Pen to get rid of excess buildup.
If dirt and dust have gotten built up on the rubber portion of the printer roller, it also can
be cleaned with alcohol and a cotton swab.
Again use the Stage Label button to rotate the roller and wipe the Roller with an alcoholmoistened cotton swab. Rotate the roller again and repeat the above procedure until the
roller is clean.
WARNING
FOR SAFETY: Do NOT touch Rollers with your fingers while
the Rollers are in motion.
