1.1 Introduction
Thank you for purchasing the CAS LP-2 price computing electronic printing scale. We have
designed this equipment with many advanced features, high quality construction, and user-friendly
menu driven programming. We are confid ent that you will find the CAS LP-2 scale will meet all of your
most demanding needs.
Sales data is easily acquired through many of the available reports which are quickly accessible
through the on- screen menus. Also available: 4 inch per second printing speed, 53 preset keys (106
using the SHIFT key), and several operation modes that enable you to control & limit access to the scale.
For larger operations, there is an in-store network that can have up to 32 scales. Another
powerful feature is RS-232 port, which can tie a scale to a personal computer (P.C.) for exporting or
importing program data. Because PLU and all other data files are kept locally in each scale’s RAM
memory, the scale’s speed is the same in a Network setting or as a stand-alone unit.
The LP-2 can be easily used with a wide variety of industry standard thermal labels. By simply
entering a label’s length and width dimensions, you can use practically any of them on the LP-2! You
can also use continuous strip labels or even thermal paper. You also can print logos, templates, NutriFacts panels, ingredient messages, advertisement lines, and more.
Remember, for proper installation and maintenance please refer to the LP-2 Service Manual. A
wide variety of supplies, accessories, and expansion options are available through CAS (USA)
Corporation for whatever your new and increasing demands may require. Before attempting any
repairs or servicing please look over this manual careful or contact CAS (USA) Corp.
The LP-2 also comes with a trial version the SP-2 software package. This software runs on any PC
using the Windows 95/98/2000 operating system. You can use the SP-2 program for as long as you
would like. You can design your own label formats on your computer screen and save them to your
hard drive. With this WYSIWYG interface, the labels you see on-screen appear exactly “as they will
print.” You can also manage all of the LP-2’s programs and options like pricing, PLU programming, etc.
You can upload data from an LP-2 or download data, perfect as an emergency backup system. All this
and many more features are packed into the SP-2 software package. The full version of the SP -2 system
will allow you to transmit and receive data from the scales. This makes the SP -2 software package an
indispensable commodity for your business as.

2.2 Assembly of Display Column
1) You must follow the instructions in this section in order to assemble the Display Assembly properly.
To begin the installation, make sure that the scale is unplugged from any electrical source. Your
scale body has a display column bracket in the rear that the display column slides into. (See
fig.)
2) Hold the display assembly in front of you such that the display assembly forms the figure “7”.
Next, with the scale’s keyboard facing you, insert the display column into the display bracket.
When the display column reaches the bottom of the display bracket, you will “feel” the
connectors “snap” together. (See fig.)
3) Underneath the display bracket you will find 2 screw holes for the display assembly screws. Insert
and fasten the 2 display assembly screws. Yo u are done! (See fig.)

3.1 Environmental Considerations & Safety
1) Please avoid the following hostile conditions:
§ Temperatures below or exceeding:
-10º C ~ 40º C (14º F ~ 104º F)
§ Excessive vibration § Unstable or flimsy surface
§ Wind or fans functioning in direct
contact with weighing platform.
§ Direct sunlight § Dust or dirt
§ High humidity § Poor ventilation
2) Environmental Protection: The scale should be installed in a dry and liquid free environment. When
the scale is installed in a high humidity or wet-type environment, be sure to avoid spilling or spraying
directly on any surface of the scale.
3) Personal Safety: It is extremely important to be aware of personal safety whenever maintaining or
operating this equipment. Wherever possible, we have tried to place warning labels and other
indicators at the actual location on the equipment where the danger is most likely to occur. However, it
is not always possible to fo resee all dangerous situations. Warnings and cautions that are necessary for
the safe operation of the scale are contained in this manual. Please, make sure to carefully read ALL
warnings and cautions before operating the scale.
4) Observe the follow ing safety precautions:
§ Shut the scale OFF and unplug the scale whenever you are changing the label
roll or whenever working in the printer bay.
§ The outlet that the scale is plugged into, should be properly grounded.
§ Whenever connecting or disconnecting ANY cables from the scale, be sure to
hold the cables by the end connector. Failure to do so may cause a short
circuit.
§ Maintain a static free work area.
§ Never use any other equipment on the same line: it should be a dedicated line.
§ The outlet used must have the proper voltage ratings.
§ Ungrounded electrical outlet
§ Shared electrical outlet

3 Proper Operation
3.2 Leveling and Location
1) Location: This scale must be placed on a flat and stable surface. Please keep the scale away from
the direct path of oscillating fans, ventilation systems, or strong drafts as these air disturbances can be
picked-up by the scale’s very sensitive weighing platform and may cause incorrect weight readings.
2) Leveling: If the scale is not properly leveled, please adjust the 4 adjustable legs at the bottom of
the scale. Turn the legs clockwise or counterclockwise so as to center the bubble of the leveling gauge
inside the indicated circle. Turning the adjustable legs counter -clockwise (viewed from top of scale) will
lower that part of the scale. Turning the adjustable legs clockwise (viewed from top of scale) will raise
that part of the scale. (See Fig.)
7
3 Proper Operation
3.3 Power Outlet and Requirements
1) The LP-2 is designed to be used almost anywhere in the world! Like the many appliances of today,
the LP-2 is designed with an automatically switching power supply. This allows operation when
connected to an AC source from 85V to 240V at 50/60Hz with 5% tolerance.
Remember: a switching power supply does not imply that bad, noisy, or improperly wired power
lines will be problem free. With that in mind, please make sure that the power lines used for the LP-2
are dedicated lines with no high-noise devices (such as compressors, motors, etc) running on it.
Also, make sure that the wiring to the electrical socket is correct. If yo u are uncertain as to the
state of your business’ electrical lines, please contact a certified electrician.
2) Once you are sure as to the safety of the electrical line, make sure to ONLY plug the scale into a 3prong outlet. The third prong is a safety gr ound and an electrician should properly wire this if it is
not correct or if you are unsure. Failure to this CAN result in electrical shock from use of this or any
electronic scale.
3) Do not use any 3-prong to 2-prong adapters or break -off the third prong from the LP-2 power cord.
The third prong is necessary and must be properly connected.
4) If you have any problems or questions regarding this matter, make sure to contact the CAS USA
Service Department.
Note: Be sure to check the LP-2’s serial number plate on the back of the scale for power specifications.

5.1 Installation of the Label Roll
To install the labe l roll at ANY time you must follow the directions in this section:
1) Press the ON/OFF key and make sure that the display is completely off. Open the printer’s sideaccess panel. As you can see, there is a detailed diagram affixed onto the inside of the side-access
panel. Use this diagram (or this manual) for future reference on how to properly install the label roll.
(See fig.)
2) Find and remove the Pick-Up Spool assembly and the label - roll Pin. Also, find the Print Head Release
Lever and push it in the direction indicated. The print head will be in the “UP” position. If there were
any labels previously installed please remove all the collected backing paper from the Pick-Up
Spool assembly. The Pick-Up Spool assembly automatically collapses when it is removed from the
Pick-Up shaft. This makes the removal of the backing paper very simple. Also remove the
cardboard paper roll core if there was a label roll previously installed. (See fig.)

MAKE SURE YOU HAVE DONE
THE ADJUSTMENTS AT POINTS
1, 2, AND 3 BEFORE YOU LOCK
3) Take the new roll of labels and find the ending. Peel-off and discard about one foot (12 inches) of
labels from the backing before installing the roll into the scale. Place the label in the scale as shown
and thread the backing through the appropriate places. (See fig.)
4) Please view the checkpoints on the diagram below as you read these directions to thread the labels.
• Feed the backing paper over the width-adjusting Pressure Shaft lifting the Pressure Plate in order to
place the backing between the two making sure that the width adjustment is as exact as possible
without bending the backing paper.
‚ Feed the backing paper inside the slot between the Gap sensor assembly making sure that the labels
travel under the Secondary width-adjuster.
ƒ Make sure that labels are pushed all the way to the left on the Peel -Off bar.
„ Feed the backing over the Rubber Roller and under the Print Head being careful not to touch the
underside of the Print Head.
… Continue to feed the backing paper over the Peel-off Bar.
† Continue to feed it under the Return Roller.
‡ Feed the backing under and around the Pick -Up Shaft.
ˆ Now attach the Pick Up Spool assembly onto the Pick-Up Shaft and turn it slowly counterclockwise in
order to tighten the backing paper.
5) Push the Print Head down in order to lock it back in place. You will feel and hear it lock in place.
Close the printer access panel and press the ON/OFF key. You have completed the label roll
installation. (See fig.)

5.2 Menu and Data Entry System
The CAL Main Menu screen looks
like this:
Pressing ESC from this
menu will take you out of CAL
mode and effect all of the
changes that you may have
made.
Menus & Sub-Menus: Any menu or sub-menu screen that you access can be exited by pressing the ESC
key. This will take you back to any previous menu or sub -menu except if you press ESC from the CAL
Main Menu. The picture above is an example of a menu. Any menu that you access by selecting
options 1 to 5 will be a sub-menu of CAL Main Menu. Any menu that you access from a sub-menu will
be a sub menu of that menu, etc. This way you can always backtrack to the CAL Main Menu by
pressing the ESC.
Entry Screens: An example of an
entry screen is shown here. If you
access an entry screen you can
exit it without making changes by
pressing the ESC key. This will
have the effect of returning to the
previous screen, menu, or submenu, whatever be the case. If
you are on an entry screen you
can save & exit that screen by
pressing the SAVE key at any point. Pressing the ENTER key while the cursor is on the last field (bottom)
of an entry screen will have the same effect as pressing the SAVE key.
Fields (on-screen): Entry screens have fields that contain data that you can modify. This data is always
contained in brackets: [123456] or [ABCDEDG ]. To select a field, simply use the ↑ or ↓ keys to
move the cursor to that field.
• A field’s name followed by a colon will usually appear on the left side of the bracketed data. In
the Sample Entry Screen above, the word “Unit :” appears to the left of the brackets
containing the value 1. To the right of the Unit field is the options that you may select: 0 is
kilograms & 1 is pounds. These are the only two acceptable values for this field. Any values
selected outside that range will automatically replaced with values within that range.
• The Label Format Field is slightly different. This field indicates its range in parenthesis listed after
the field’s name. In this case it is 1 to 999. Also, the data that appears to the right of the entry
field brackets changes dynamically as you type. For example, if the cursor is on the Label
Format field and you press the CLEAR key you will see that the format number will change to 1
and the name of label 1 will appear on the right side of the brackets. If you press the 1 key &
then the 2 key, then the name of label 12 will appear . If you now press the 3 key then the name
of label 123 will appear.
• The Unit Price field tells you that the values are in 2 decimal place format and that this is a $
value. The right side shows “ / lb” which means that this is a $ per pound field.
Cursor: The cursor is a flashing block character that will always appear on the first (top) field of an
entry screen. In all LP-2 manuals the cursor is shown as the underscore character _ instead of the block
character for legibility.

Span Fine Adjust: Does not require weights but they are recommended for checking the Fine
Adjustment.
Gravity Constant: This is a value that causes automatic compensation for different altitudes. If the scale
is calibrated in NY and shipped to CA, you can simply enter the Gravity Constant for CA and the scale
will be calibrated for CA even though it was calibrated in NY.

• You are using 60 lb of certified weights.
• The scale has prompted you for 60 lb and not 30 kg or any other capacity.
• The weight/counts were stable throughout the calibration process (+ 5 count ∆).
• There is nothing obstructing the platter & the platter is mounted properly onto the platform.
• You are using the correct platter and/or correct dead load (IZR* is 10% of capacity.)
• Try process again 2 more times always following the onscreen directions.
v If problems persist, you may have a damaged: A/D Converter (90%).
v If problems persist, you may have a damaged: Load Cell (5%).
v Contact the CAS Service Department: Other (5%).
NOTE: Any changes made here will affect the NTEP Audit Trail counters (CAL counter only.)

7.3 Span/Zero Fine Adjust
Once at the CAL Main
Menu screen, press the 2 key. The
display will read “Checking Load
Cell…” and then the Span Fine
Adjust screen will appear as
follows:
WEIGHT: The Weight display will be shown in calibrated units (lb if you calibrated in lb, kg if you
calibrated in kg.) The weight is in 1/60,000 resolution and updates a bit more slowly than in
REG mode. You can use this mode to verify different weigh points. Remember that the REG
mode weight display will round up to the nearest 1/3000 division.
SPAN: The Span value is the measurement in counts of the full load. Increasing the span will display
a lesser weight for a given mass; decreasing the span will display a greater weight for the
same mass. After you change the span value, while the cursor is on the Span field, you need
to press the ENTER key twice in order to refresh the weight display.
