1. Important Notes
1.1 Overview
The 720 is a fully automatic print and apply machine. Handling is very easy and can be learned
with a minimum of training. For operation, only a few adjustments are necessary. The machine
is controlled by a microprocessor and because of its programmable functions it can be used in
many applications.
Except of cleaning the print head, rollers and the different sensor’s there is no periodical
maintenance necessary.
This manual should help you to operate the 720. In chapter 2 the machine is described and
many expressions are explained. For normal operating chapters 3 and 4 are important. All
other chapters give additional details of the machine.
The ALX 720 is available in a right- or a left-hand version. The expression right or left is related
to the direction of product transport. In the following, a right hand machine is explained. For the
left hand version all explanations have to be mirrored.

2. Description
This chapter explains the structure and the function of the 720 dispenser part. The expressions
used are explained here.
CAUTION! - The machine is connected to mains. Only authorised
personnel may open the cover. Operation without this cover is not
allowed.
2.1 Mechanics
The label material is unwound from roller (003). The maximum diameter of the label roll is 300
mm. Max. width is 100 mm. The material roll is guided by 2 removable plates (002). The guide
plate in front has to be pressed against the label roll. Behind the cap (004) of unwind mandrel
(003) an adjustment screw for the brake is located. The unwind brake avoids after run of the
label roll when the label drive stops. The dancer arm (011) keeps the material tight and the
acceleration forces low. The deviator roller (008) makes sure that the material is guided
correctly.
Note: For labels longer than 100 mm and in "side labelling applications" it is
recommended to use the optional available kit dancer arm controlled unwind brake.
This device avoids uncontrolled after run of label material. The brake should not be
fixed too tight, otherwise the motor may stall or the material web gets broken.
Behind the deviator roller (009) the material is guided to the printer unit. First it passes the both
opposite holder for the label sensor. The sensor could be positioned across the whole label to
get the optimised position. In one of the two red guides a sensor to detect end of material is
mounted. Behind the print unit the material is hold in a loop buffer. The loop is controlled by the
position of the dancer arm. If the loop is not filled, the printer starts to fill the loop again. At a
adjustable position all further starts of the dispenser are ignored. Behind the loop the material is
guided to the dispensing edge. The brush (006) keeps the material tight without disturbing the
movement. At the dispensing edge (010) the label sensor (007) is mounted. The label sensor
detects the gaps between labels. The label sensor comprises of a light source and a light
receiver. The sensitivity can be adjusted by the operators panel.
At the dispensing edge (010) the label is separated from the backing paper. By means of a soft
(005) roller the label is applied on to the product. Roller (012) makes sure that the material is
always guided properly around the dispensing edge. Drive roller (001) keeps the transport
speed of the material constant. Deviator rollers (012) guide the backing material around the
drive roller (001). The pressure mechanics (013) press the backing paper against the drive
roller (001).

With the handle (015) you may open and close the pressure mechanics (013). When inserting
the material the pressure roller has to be opened. Dispensing is only possible when the handle
(015) is in the closed position. Via the deviator roller (016) the backing paper is guided to the

rewind mandrel (017). The cone between the 4 pins can be pulled out to allow the reward
backing paper to be removed.
Except for the drive roller (001) and the material brush (006) the 720 has no wearing parts. The
operator panel (019) is described in the next chapter.
A threading diagram is affixed to the front of the 720 which shows how the label material should
be threaded through the machine.
Screw (014) secures the position of the pressure roller (013) in a lateral direction. In order to
achieve a reliable run of the label web position, adjust the roller to the centre of the label web.

The 4 soft keys have following functions:
FEED By pressing this key one label will be dispensed. When the machine
displays INIT pressing this key will start initialisation of the machine. An
initialisation has to be made each time a new material is used. If the FEED key is
pressed and held as the machine is turned on then the machine carries out an
automatic initialisation of the label parameters "CONT" and "LPIT".
PRIOR This key moves up the menu or increases the value of a (Prior
function) parameter. If the up arrow key is pressed and held as the machine is
turned on the product menu is selected.
NEXT This key moves down the menu or decreases the value of a (Next
function) parameter. If the down arrow key is pressed and held as the machine is
turned on the standard menu is selected.

3. Preparing the machine
3.1 Installation
3.1.1 Unpacking of the unit
y Before removing the unit off the box, don’t hold the machine on the dispensing edge, printer
unit to prevent disadjustment off the machine.
y For mounting the machine, a complete system of holding tools is available. Ask your Avery
representative.
y Take care that the machine is safe and stable mounted.
y There are rotating parts on the machine. Do the necessary actions to prevent that anybody
can be caught from these parts.
3.1.2 Connection of the machine
Before connecting the machine to the mains, check the correct setting of the line voltage. For
the connection of sensor, applicators e.g. see the chapter connections. Fix all cables to prevent
accidents and damaging of cables. Have also a look to the EMI chapter for proper machine
operation.
For checking of correct operation of sensors, applicators use the check functions SCHK, I_CH
and O_CH.
3.1.3 General setting
Normally the setting is done, but before operation check and note the general dispenser
configuration: dispenser direction, machine type, applicator mode, and APSF function.
The printer function IFAC / PORT has to be set to RS23.

3.2 Preparing the Dispenser
3.2.1 Inserting material
Insert your label material in the machine to follow the instructions in the chapter Operation /
Threading.
3.2.2 Defining label data
For correct dispenser operation, you have to tell the machine the length of the label and adjust
the label sensor. Normally this is done automatically. For this follow the instructions in chapter
Operation / Initialise material. For initialisation of the dispenser set the printer to OFF.
There are some reasons the automatic initialisation is not possible:
y Using another then the standard optical label sensor
y Label material with a low contrast ratio between label and backing paper
y Labels with holes inside the label
In this case you have to set one or both of the parameter manually. Activate the extended
standard menu to do the settings by:
y Pressing both keys NEXT and PRIOR simultaneously
Display: CODE
y Password CODE entering:
1 time pressing the key PRIOR FUNCTION
2 times pressing the key NEXT FUNCTION
3 times pressing the key ENTER
Display: LPIT
y Setting the label length
Enter the LPIT function by pressing ENTER. Measure the distance from one label edge to
the edge of the next label. Enter the value in mm by using the function keys. Press ENTER
to leave the function. See also the information below.
y Change the setting of the label sensor
If another label sensor then the Wenglor type will be used, call the CONT function and set
the value to any M006.
If the contrast ratio is low, follow the instructions to adjust manually contrast.
y To store the setting permanent leaves the menu with the quit function. If you power off the
machine without quit all modification are lost.
y By pressing the key FEED one label can be dispensed if you are in the parameter selection.
Setting LPIT manually
To initialise labels with cut outs such as the one shown below - the "LPIT" parameter should be
used to enter the label pitch of the label web.
All other label edges seen by the label sensor will be ignored until the distance adjusted in the
"LPIT" parameter has been fed through the label sensor.

y Remove a label from the backing paper and slide it inside the sensor.
y Reduce the value with the PRIOR key until the LED switched on.
y Press the key NEXT until the LED switched off. If there are marks on the backing paper do
the measurement on this position.
y Note the value GAP xxx
y Slide the backing paper including label inside the sensor. Use the lightest position on the
label for the adjustment.
y Increase with the NEXT key the value until LED lights again. Note the second value GAP

y Calculate the contrast value by the formula (xxx + yyy) / 2 and set it.
y Manual adjustment is completed.
With a difference of less than 20 an operation with this kind of sensor is not possible
(sometimes two or more labels are dispensed).
3.2.3 Label guide
On some of the axles there are guiding clamps. Adjust the clamps near the machine so all have
the same distance to the front plate (31.5 mm). The outer clamps should be mounted that the
guide but not bend the label material.
The front of the dispensing edge has a rot, which can be adjusted for straighten the material
guiding. Switch the printer to OFF and spend several labels by pressing the dispenser FEED
key. If the material guiding is running out of the guiding way, adjust the rot by loosing two
screws at the dispensing edge.
4/09 Page 19 Preparing the machine
Operators Manual
ALX 720
3.3 Dispenser Setup
For adjusting the dispenser function, set the printer to OFF.
3.3.1 Stop position
The first step is to adjust the stop position. This is the basic adjustment of the dispense
process. Also in case of problems with the machine check if the stop position is okay.
Figure 7 Stop position
The stop position should be adjusted so that the label stops at the dispensing edge or up to 3
mm behind.
For a correct operation of the automatic label compensation, they will compensate a missing
label on the web, first the distance between label sensor and dispensing edge has to be
defined. Do this by calling the DIST function in the configuration menu. Check the setting by
removing a label before the label sensor from the web. Give a start signal to the machine by
triggering the start sensor (not the FEED key) and see if the compensation is done on the right
position. Do the fine adjustment with the STOD function.
3.3.2 Fixed dispensing speed
The second step is to adjust the dispense speed. If an APSF sensor is used see 3.3.3.
If an applicator is used, the dispense speed has no influence to the dispense process. Continue
with 3.3.4.
Set POS to the distance between start sensor and dispensing edge. If installed remove the
roller to press the label onto the product. Now try to dispenser one product. If the label has
wrinkles reduce the speed VELO. If the product peels out the label, so the stop position of the
next label is before the last position increase the speed. Normally your dispense speed should
be a little bit higher then your product speed.
3.3.3 Automatic dispensing speed (APSF)
With an connected rotary encoder the dispensing speed follows the measured product speed.
To adjust the speed use the EGRA function located in the extended standard menu. The
measured speed will be displayed in the VELO function. Do the adjustment in the same way
described for fixed speed.
4/09 Page 20 Preparing the machine
Operators Manual
ALX 720
3.3.4 Label position on the product
At least adjust the position of the label on the product with the POS function or with the STAD
function, if an applicator is in use.
3.3.5 Product data bank
Save your setting in one of the product data banks. If different products and / or labels are in
use up to nine different combinations could be stored. Define and store the different product
data. The select the product data bank mode by holding the PRIOR key during power on.
Switch back to normal mode by holding the NEXT key.
3.4 Preparing Printing
3.4.1 Adjustment of foil unwind / rewind tension
Insert the print foil according the instruction in the Operation chapter.
The torque of foil unwind-and rewind mandrels are adjustable by means of the red hexagon pin.
The foil should run free of wrinkles respectively should not be stretched (especially at drum
section) over the whole run from roll to roll.
Increase of torque at unwind/rewind mandrel Foil must not be stretched
Decrease of torque at unwind/rewind mandrel Foil must not have wrinkle
The factory adjustment covers a wide range of foil width which is the main factor for
the torque. Use of very narrow and very wide foil however may need a readjustment.

3.4.2 Positioning of full size gap sensor
The unit is equipped with a full size gap sensor. From the minimum label width (25,4 mm) to the
maximum the sensor can be moved to the wanted position.
As shown on the pictures below, the sensor can be moved in two parts – the lower side and the
upper side. Both should match so the beam can run from the diode to the transistor! If that is
not adjusted properly the sensor can not work!

y Switch printer to OFFLINE mode and lift print head by brief pressing of the FEED key. Open
front cover.
y Hang document material in reel holder in a way to ensure unwinding that label in the printer
section is on the top. Put outer guide disk onto mandrel. The 2 guide plates keep the label
roll reliably in position on the unwind mandrel.
y Guide material around the dancer arm.
y Press the red lift lever at the right, outer end of the print module in order to lift the pressure
rolls of the feed roller and insert material below the print head. Adjust both pressure roll
units symmetric to material width so that material moves smoothly.
y Labels behind the dispensing edge should be removed. The material brush has to be
positioned in a way, that the material is kept tight. From time to time it is recommended to
reverse the mounting of the brush while you are loading a new label roll.
y Adjust the pressure roller before the rewind, so that it is right in the middle of the material.
Close the pressure roll and turn the roll 2 or 3 times, so that the material is threaded. Check
that the material is guided straight.

Attach empty foil core onto mandrel on left-hand side.
y Insert foil end diagonally from the front under print-head holder and print head holder with
open hinge drive mechanism. If foil is changed during a print job, lift print head by short
depression of the FEED key.
y Pull foil upward and simultaneously move it towards printer.
y Guide foil around feed roller and attach it to foil core in anticlockwise direction (foil may be
folded so that adhesive part at start of foil can be used).
By simultaneous depression of the (ON/OFFLINE)-and (FEED)-keys, material and foil can be
advanced until perfect unwinding of foil is warranted.
Note: Sometimes it is helpful to release the head and rotate the head to insert foil
into the printer! As well rotating the head means that the wires connected to the
head can be to short – then please disconnect the wires – only if the printer is
switched OFF ! Do not forget to connect again – and check if the connectors are
properly mounted!

4.3 Initialise new label material for dispenser
The 720 requires data of the label material in use i.e. label length and opacity of the label and
backing material. In most cases those parameters can be scanned during automatic
initialisation. This is not always possible.
During initialisation the 720 uses its label sensor to determine where the labels are on the label
web and the distance between the leading edge of labels (the label pitch) so that they can be
positioned correctly.
There are several modes of initialisation which will be explained later, but in most cases
initialisation should be executed in fully automatic mode. For fully automatic initialisation the
"LPIT" and "CONT" parameters should be set to "AUTO". Initialisation can be executed by
pressing the <FEED key> whenever the message "INIT" is displayed by the machine.
The message "INIT" is displayed in the following cases:
a) if the <FEED> key is pressed and held during power up
b) on return to the standard menu after the "CONT" or "LPIT" parameters have been changed
to automatic mode
c) on return to the standard menu after the configuration menu has been used
d) after clearing the error messages E__0 or E__1 in the standard menu. (If the feed key is
pressed while another parameter is displayed, the data from the last initialisation is held
and the first label edge detected is simply moved to the position defined by the "STOD"
parameter)
To start initialisation simply press the <FEED> key when "INIT" is displayed.
The machine will slowly feed the label web while it searches for the gaps between labels and
measures the label pitch. When the machine has determined this information it will move the
first label edge found during the initialisation process to the position that has been adjusted with
the "STOD" parameter. After initialisation has been completed successfully ("ON") is displayed.
Initialisation can only take place in the standard menu; it is not required in the product menu
since all label data is already stored in the machine's memory. After a E__0 or E__1 message
has been cleared whilst in the product menu the first label edge detected at the next press of
the <FEED> key will be moved to the position defined by the "STOD" value stored in the
machine's memory.
However, when changing to a new product bank or changing label rolls the FEED key should
be pressed once so that the label sensor can find the next leading label edge and move if to the
correct dispense position previously defined by the STOD parameter

If you do not press a panel key while turning on the machine the same menu is active that has
been used before the machine was switched off.
Function Display message
4.4.2 Missing label function and web breaks
The missing label function stops the label web in the correct position even when a label is
missing from the label web. If there are more than 3 missing labels from the web then the
machine will stop and give the correct message E_1.
If the label web has broken or come to an end then the machine will no longer be able to find
the next leading label edge and so after more than 3 signals from the product sensor the error
message E_1 will also be generated.
4.4.3 Display and data input
The operation of the machine is controlled by the operator panel. Data can be displayed and
changed. The displays have different meanings:
y Parameter selection:
In the display a parameter is shown, e.g. POS, STAD, or PD02 (product menu no. 02).
By pressing the keys FUNCTION another parameter can be selected. By pressing the
key ENTER the data is displayed.
y Data display:
The display shows the values of the parameters (e.g. 0123) or possible adjustments
e.g. (AUTO). The data value is changed by pressing the FUNCTION keys. By pressing
the key ENTER the data input is completed and a new parameter is shown.

y Error display:
If the display shows e.g. E__XX, the 720 (dispenser) has recognised an error. A
warning is shown by W_XX. As soon as the error has been corrected, you may erase
the message by pressing the key ENTER and you will get back to the status the
machine was in before the error was indicated.
Note: Data entered in the standard menu are not stored, if the 720 is switched off. If
you need to store data you have to use the extended menu. Please check if it is of
help for you using the product menu in your application.

The labelling position is also changed by variation of the product speed. In this case first control
you product speed and the dispense speed VELO. Only if both speed matches adjust the
position with the POS function.
Figure 14 Label position
Stop position ___________________________________________________ STOD
The stopping position (STOD) defines the position where the label stops after it has passed the
label sensor. The value represents 1/10 mm. In the example 0760 has to be adjusted by
pressing the FUNCTION keys. If an increased value is chosen, the label is advanced further, in
case of decreased values the position is closer to the label sensor.

Operators Manual
ALX 720
Dispense speed __________________________________________________VELO
The speed value VELO displays the dispensing speed in 0.1 m/min. The product conveyor
speed has to be constant to assure accurate labelling. A change of the product speed causes a
different position of the label on the product. In case of inaccurate labelling, it should be
verified, if the speed of 720 and your product match together. This is done automatically if the
optional automatic speed follower (APSF) is installed.
If the 720 is equipped with an applicator, two parameters in the standard menu can be
changed. The delay time which specifies the moment when the applicator must put the label
onto the product and the blow time - how long the applying of the label should take.
Start delay ______________________________________________________STAD
By the aid of the parameter STAD the period of time between the recognition by the product
sensor and the dispensing of the label onto the product is determined. The time units are ms,
the time is adjusted by the keys FUNCTION.
Blow on time ___________________________________________________ BLOW
The labelling time BLOW indicates, for how long the applicator should apply the label onto the
product. This time is displayed in ms also. BLOW is equivalent to APT2 which is found in the
extended menu.
Product menu____________________________________________________ PD0n
This menu can be used for storing data for different labels and products. 9 different sets of
product data can be programmed.
If you want to switch to another product, select the respective product number by pressing
NEXT and PRIOR, then press ENTER. Now the new product data are activated.
To change the labelling parameters you can call the extended menu. After leaving this menu
your product data will be automatically updated.
720 carries out the labelling of your products completely automatically.
Check now and then:
y if there is still enough labelling material on the unwind roll
y if an error has been displayed and 720 no longer effects labelling
y if the label is placed correctly onto the product. If this is not the case, correct the respective
parameter in the standard menu.
Control is even more simple if you use an OD-control, which measures the diameter of the
material roll and indicates a warning message W__5 as the label roll diameter gets too small,
i.e. there are only a few labels left on the label roll. To the warning output you may connect an
alarm indicator, an optical or acoustic signal can be triggered.

4.6 Maintenance
Clean print head and feeding roller with cleaning liquor from paper, adhesive and ink deposits
at regular intervals.
4.6.1 Cleaning print head
CAUTION! - The print head is an electronic module and highly sensitive to
static impacts. For that reason discharge your static potential before going in
contact with the print head by gripping the base plate of the printer. Do not
y Disconnect unit and pull off the mains plug.
y Remove material and foil.
y Loosen socket screw at centre of print head axle, until the print head can be rotated
upwards.
remove plugs from the print head.
Note: If print head is readjusted at axle mark it’s position accordingly.
y Clean print roller with dust-free cloth and cleansing liquor only.
CAUTION! - Never use knives or objects with sharp edges for cleaning. Metal
objects must never get in contact with the dot line.
y Put print head to former position and fix screw again.
Note: The screw enters a non visible gap at the axle, which ensure the correct
position of the print head. Factory adjustment is flash with the inner black plastic
bushing.
CAUTION! - Before switch on the unit, check that both connectors of print
head are still plugged on correctly. Reconnect if necessary.
4.6.2 Cleaning of Print Roller
y Disconnect unit and pull off the mains plug.
y Remove material and foil.
y Loosen screw at centre of print head axle - until the print head fixation can be rotated
clockwise.
Note: Do not remove plugs form the print head. If print head is readjusted at axle
mark its position accordingly.
y After performance of this step, the feed roller as well as the print roller is accessible from
above.

ALX 720
y Clean print roller with dust-free cloth and cleansing liquor only.
y Rotate roller stepwise for complete cleaning.
CAUTION! - Never use knives or objects with sharp edges for cleaning.
y The feed roller and the friction rollers are also to be cleaning from time to time. Avoiding any
type of contamination in the printing area generally increases performance of the printer and
particularly the print head.
y In addition, neat printing results are preferable to poor ones in any case.
y Put print head to former position and fix screw again.
Note: The screw enters a non visible gap at the axle, which ensures the correct
position of the print head. Factory adjustment is flash with the inner black plastic
bushing.
y Before switch on the unit, check that both connectors of print head are still plugged on
correctly. Reconnect if necessary.
4.6.3 Cleaning of foil guiding parts
Adhesive residues are to be removed at regular intervals upon processing of self-adhesive
material to ensure perfect print quality. Clean parts with dust-free cloth and cleansing liquor
only. Contaminated parts affect the feed of the foil and will reduce the print quality.
4.6.4 Dispenser maintenance
720 can be easily maintained and has only a few wear parts. If you change the material, note if
any glue or waste labels are stuck on the rolls or dispensing edge. In this case you have to
clean the respective parts. The machine has to be cleaned at least once a week. Glue and
waste labels have to be removed from the rollers, the dispensing edge, the material brush, and
possibly from the applicator. All rollers have to be cleaned from any grease. We will supply a
special cleaning set for this. The material label sensor has to be cleaned from dust regularly.
The material brush should be turned around whenever the material is changed. Any glue has to
be removed from the brush. If there is a soft roller at the dispensing edge for applying the label
to the product, check if the roller is damaged or dirty. Replace it if necessary.
The unwind has to operate in such a way, that the dancer arm does not bounce to its end
position. If this is not the case, the friction mechanism has to checked.
If the backing paper is not wound up accurately, the belts have to be tightened.
CAUTION! - Check the electrical connections, especially the mains cable for
unreliable connection.

5. Dispenser adjustment
The touch panel keys or the optional interface can change labeller parameters. The last
entered parameters are the actual ones the machine works with. Programming via the interface
is described in chapter Serial interface.
There are 2 levels for parameter adjustments. The first one is for parameter selection. With the
keys FUNCTION a parameter is selected. By pressing the keys ENTER the second level can
be reached. Pressing the keys FUNCTION can change the parameter values. By pressing
ENTER you quit the parameter adjustment and the next menu point is shown. For some
functions the change of values is effected immediately, for others when leaving the menu point.
Details in the menu functions.
There are 4 different menu structures:
• Standard menu
This menu is used for normal operation. The most important parameters for the production
can be changed here. The adjustments are lost after turning off the machine.
• Extended standard menu
This menu offers additional parameters and functions to those in the standard menu. Any
adjustments made in the extended menu are stored on quitting the menu and are
maintained even if the machine is then turned off.
• Product menu
If data banks are stored in the extended menu, the product menu can be activated. In this
menu, programmed data banks only can be selected. Changing parameters in this menu is
not possible. When storing data in a new data bank, the current adjustments are saved to
the new product data bank. You may change data values of a stored data bank by loading
the data from the extended standard menu, modifying them and resaving them in a data
bank.
• Configuration menu
In this menu, you configure the machine according to your applications. Additionally you
have access to service test functions. This menu is mainly dedicated to service technicians.
All current parameter settings are stored on quitting the configuration menu and are
maintained if the machine is then turned off.

Product length ___________________________________________________PRDL
Function: The product length avoids multi labelling in case of difficult products. Normally it is set
to AUTO. This means that the product length is set to the label length.
After the product sensor has detected the edge of the product all signals that might be triggered
while the product is passing the product sensor are inhibited. This function can be helpful in
cases where the product is transparent or has several detection marks or edges. Such a case
is shown below.
The product sensor supplies several signals while the product passes the product sensor. If the
PRDL is not adjusted according to the dimension of the actual product the warning W_0 may
be given of false multiple product detection signals. The defined product length suppresses all
signals after the first product sensor signal has been received.
By pressing the keys FUNCTION the parameter PRDL is selected. The data input is selected
by pressing the key ENTER.
If an applicator is fitted to the labeller, the product length is not defined as a distance but as the
time that the product needs to pass the product sensor. The time is adjustable between 5 and
9999 ms.

Start delay_______________________________________________________STAD
Function: Delay time for the dispensing by means of an applicator after the product has passed
the product sensor. This value influences the position of the label on the product.
Only available if applicator is used.
Range: 1 to 9999 ms
Dispensing speed ________________________________________________VELO
Function: The labelling speed may be adjusted with the parameter VELO. Values between 0.2
and 30.0 m/min are possible. The speed has to be adjusted so that it matches the product
speed.
When an applicator is fitted to the machine, this parameter defines how fast the label will be
dispensed on to the applicator.
EGRA value check ________________________________________________ STST
Use this function to adjust the EGRA value. If the drive-roller speed is higher than that of the
conveyor then increase the EGRA value, if it is lower decrease the EGRA value so that the
conveyor speed and drive-roller speed match.
Slew speed _____________________________________________________ SLEW
Function: For some situations the labeller can run with a different, higher speed. This occurs
during compensation of a missing label on the web, positioning the label at the dispensing
edge during initialisation or after pressing the feed button if the APSF-mode is selected. The
resulting speed depends on the selection (FAST or SLOW) and the APSF-mode.
SLEW setting FAST SLOW
APSF off Max speed VELO
APSF on Max speed 12 m/min
Electronic gear ratio adjustment ___________________________________ EGRA
The parameter EGRA appears in the extended menu only after the APSF function has been
switched on.
The range of the EGRA parameter is 100 to 500, representing from 1 to 5 encoder pulses per
millimetre of conveyor movement. The full EGRA range can be used up to 30 m/min conveyor
speed.
With an applicator there is no realistic limit to the conveyor speed and at very high-speeds an
EGRA value at the lower end of the range should be used.
Dwell time _______________________________________________________ APT1
Function: Only used when an EP- applicator is necessary. It defines for how long the pneumatic
cylinder is switched on.
Available only with applicator.
Range: 1 ... 7500 ms
4/09 Page 51 Dispenser adjustment
Operators Manual
ALX 720
Blow on time ____________________________________________________ APT2
Function: Only used when an applicator is necessary. It defines for how long the label is blown
onto the product.
Available only with applicator.
Range: 1 ... 7500 ms
Restart delay ____________________________________________________ APT3
Function: This parameter defines the time for a next label dispense after the applicator cycling
is completed.
Available only with applicator.
Range: 0 ... 5000 ms
Time constant compensation _______________________________________ APT4
Used to control the labelling position when using an applicator in conjunction with APSF.
The parameter APT4 is set to the time that the label takes to reach the product from the start of
the applicator cycle. For blow applicators this will probably be less than 25 ms, for EP (aircylinder) applicators the time will be much more - possible 60 ms to 100 ms depending on the
length of the air cylinder.
To calculate the correct value proceed as follows:
Set APT4 to 1. Run the conveyor at a fairly low speed such as 10 m/min and note the label
position on the product. Now run the conveyor at a much higher speed such as 25 m/min and
note how far the label position has shifted back.
Use the following formula to calculate the correct value for APT4...
(LABEL SHIFT (mm) x 60) / (Vhigh - Vlow) = APT4
Vhigh represents the higher conveyor speed used (in m/min)
Vlow represents the lower conveyor speed used (in m/min)
eg. If the shift is 3mm and the conveyor speeds 10 m/min and 25 m/min are used the correct
value for APT4 is:
(3 x 60) / (25 - 10) = 180 / 15 = 12
The calculated value should then be tested by running the conveyor at a high and a low speed
and checking that the placement position does not change. If the label position moves back
slightly at higher speed then increase APT4 a little, if it moves forward at higher speed then
decrease APT4 a little.
Note: The EGRA parameter must be set correctly as well as the APT4 parameter
for correct label positioning on the product.

5.5 Menu functions
The menu functions are explained in detail here.
Permanent test___________________________________________________ DTST
The permanent test makes a test run without using labels. In the display the numbers of
dispense cycles is shown (see description LABC). Immediately after starting the function, the
machine runs in a self-test. The test run works with all adjusted parameters. The test can be
stopped by pressing the key ENTER.
Polarity of the product sensor ______________________________________ P_S_
The machine requires a start signal for each product to be labelled. After the start delay (STAD)
the labelling starts. The signal is usually created by a light sensor at the conveyor. A PLC can
also supply this signal. The light sensor supplies a signal when the light beam is interrupted by
the product. By means of the function P_S_ it will be selected whether the leading edge or the
trailing edge of the product should trigger the signal.
Usually the trailing edge of a product is used. Reasons for detecting the leading edge can be:
- shape of product (your should avoid detecting a radius or a declined edge)
In case of using other than the standard product sensor’s, the meaning of the display can be
reversed. The adjustment you need you may change with the keys NEXT or PRIOR.
Factory adjustment: LEDG
Machine type ___________________________________________________ MACH
The software is identical for several different machines. Choice the correct type.
Factory setting: The last setting remains after a factory reset.
Dispensing direction ______________________________________________ MDIR
The machine is available in a right and left-hand version. In the right hand version the product
transport is from left to right when you look to the front of the machine. The adjustment is done
in the factory and should not be changed.
Factory setting: The last setting remains after a factory reset.
Handling of missing label _________________________________________ MLAB
There are several condition the dispenser is not able to dispense a product:
y the distance between products is too close
y an additional printer is not fast enough
y the loop in the ALX720 is empty (end of job, printer error)

With this function, you can decide how to react:
NONE Do nothing. The unlabeled product will be detected later in the line.
WARN Set the warning output and displays W__0. The production continued.
ERR1 Set the error output to stop the production line immediately and display E_10.
ERR2 The first unlabeled product generates the warning. Two unlabeled products in a
sequence set the error.
ERR3 The error condition will be set at 3 unlabeled products.
Automatic product speed follower ________________________ APSF
Under parameter APSF the automatic product speed follower function can be activated (ON /
OFF). The APSF sensor is fitted to the conveyor and supplies signals that represent the speed
of the conveyor. The installation of the sensor and the adjustment of the parameter have been
carried out according to your application and should not be changed.
The compensation steps for the current conveyor speed are constantly recalculated rather than
just when the product-sensor is triggered. This means that a change in conveyor speed
between the time that the product is detected and the time it reached the dispense position has
no effect on labelling placement accuracy.
There is no optimum EGRA setting. The compensation steps are calculated using the current
EGRA setting rather than using fixed compensation step values for a predetermined EGRA
setting and so any EGRA value works just as well.
At slow speeds the label dispense speed matches the conveyor speed exactly regardless of the
EGRA setting. For instance if the dispenser needs to make 1.236 steps per encoder pulse then
at the first four encoder pulses the dispenser will make one step but will then have fallen
4x0.236=0.944 steps behind. On the fifth encoder pulse the dispenser will make two steps and
so be (5x0.236)-1=0.18 steps behind. The dispenser will always be less than one step behind.
The dispenser thus always dispenses the correct amount of label in regard to the product
movement even when the conveyor is starting from rest or coming to rest.
Type of applicator ________________________________________________APPL
In most cases, the label is dispensed directly onto the product. If this is not possible, an
applicator has to be used. We offer a number of different applicators. In this function, the
installed applicator has to be defined. You may select the applicator type you have ordered for
your application (display shows 'ASA`,`EP`, RVEP or another applicator). In case of direct
dispensing the function direct dispense has to be chosen:
Display shows 'DIR'.
The adjustment is done in the factory and should not be changed.
RVEP (ReVerse EP) operates as an EP applicator except that once the label has been
dispensed onto the applicator the applicator cylinder is extended to wait for the next product to
arrive. This provides more accurate labelling than with EP applicators because variation in the
time it takes for the cylinder to extend does not affect the labelling position.

Additional functions in the standard menu
Depending on which parameter has been defined under APPL different menu functions are
shown in the standard menu. If an applicator is used additional times BLOW and STAD for
controlling the applicator cycling are available.
Input and sensor check____________________________________________ I_CH
To display the status of sensor’s and inputs information are grouped in 3 blocks you can select
by pressing the NEXT or PRIOR keys. The character for the inactive state is different to identify
the various blocks.
Block 1 (inactive = 0)
N = Power fail detection (only can case of malfunction)

pressing key ENTER.
Output check ___________________________________________________ O_CH
With the NEXT and PRIOR keys you can select the output you will switch on for testing. Leave
the function by pressing key ENTER.
On selecting the O_CH function the display shows "1" and the first output is active. Using the
up-arrow and down-arrow keys the user can select any one of outputs 1 to 8. Only one output
is on at a time so that the user can easily see if he has any shorted connections (any output
that is being turned on by another part of the program such as an error or ODC output will stay
on until the error or ODC input is cleared).
1 = terminal 15 = BLOWON
2 = terminal 16 = AIRSTREAM
3 = terminal 17 = CYLINDER
4 = terminal 18 = PRINT_OUT
5 = terminal 19 = WARNING

Adjustment resetting______________________________________________FACT
This menu point sets all parameters back to the factory values. All parameters will be reset, so
please note all your adjustments before. When you call this function the display shows 'NO`.
After you have left by pressing the key ENTER there is no change.
When you change with the key NEXT to YES and press ENTER all parameters are reset to
default values.
Note: This function also clears all product banks.
Interface baud rate_______________________________________________ BAUD
With this function the baud rate of the interface will be adjusted. This is an option of the
machine. If you do not have this option, the parameter has to be set to 'NONE` to protect the
interface and to avoid errors. The following baud rates are adjustable: 150, 300, 600, 2400,
4800, 9600 and 19200 baud. When calling the function FACT this parameter will be set to
`NONE`. When the machine is delivered with the interface the baud rate is set to 9600. Select
your baud rate by pressing the key NEXT or PRIOR . With the key ENTER the adjustment is
stored.
Factory adjustment: NONE
Parity bit ________________________________________________________ PARI
The function is only visible if a baudrate is selected. The parity bit is necessary to check the
data transfer. In case of wrong data transfer an error message will be given. The adjustment of
both machines has to be identical. Usually the transfer is made without parity bit.
Possible adjustments:
'NO`: Not sending or receiving a parity bit
`EVEN`: produce a parity bit so that an equal number of `1` signals is created
`ODD`: produce a parity bit so that an odd number of '1' signals is created.
`0PRT`: The parity bit is always 0
By pressing the key NEXT or PRIOR the adjustment is selected and by pressing the key
ENTER the function is finished.
Factory adjustment: NO
Number of stop bits_______________________________________________ SBIT
The function is only visible if a baudrate is selected. This parameter defines the number of stop
bits. By pressing the key function you can select between `1BIT` or `2BIT`. By pressing the key
ENTER this function will be left.
Factory adjustment: 1BIT

Number of data bits _______________________________________________ DBIT
The function is only visible if a baudrate is selected. With this function you can select between 7
or 8 data bit protocols.
Factory adjustment: 8BIT
Recycle (simulates max labels/min) ________________________________ RECY
The Auto-recycle function, is used to determine the maximum possible cycle rate with the
current parameter settings.
It will cycle through applicator cycles automatically by internally generating a product-start the
instant a cycle has been completed and displays the average cycle rate per minute in the
display. It also operates with no applicator selected by dispensing labels at the maximum
possible rate. The maximum labelling rate for different values of PDT can be determined using
the RECY function without having to physically connect the printer.
Distance sensor to dispensing edge _________________________________ DIST
This function defines the distance between the material label sensor and the dispensing edge.
This value is shown in steps of 0.1 mm (e.g. 0456 means 45.6 mm). The measured value can
be adjusted by pressing the key FUNCTION.
If the DIST value has been adjusted correctly the first leading label edge detected at
initialisation will be moved exactly to the dispensing edge, as long as STOD is set to 0.0 (mm).
This parameter is important for the missing label compensation. If it is not correctly adjusted a
missing label on the material roll, will not be compensated correctly and the product will not be
labelled.
Value range: 10.0 .... 999.9 mm
Label counter ___________________________________________________ LABC
Each dispensed label increases the counter by 1. The capacity of the counter is for
999 999 999. The total number can be seen in 3 sections, press the keys FUNCTION as
described down below:
Mnnn Knnn .nnn
y where M represents millions
y K represents thousands
y .represents units
On entering the "LABC" parameter the units are displayed. By using the arrow keys can then
be used to change between the millions, thousands and units displays.
By pressing NEXT and PRIOR at the same time the counter is set to 0. By pressing the key
ENTER the function will be left.
Leave Menu finishing _____________________________________________ QUIT

Note: Modified parameter values are only stored if the menu is left by using the
QUIT function. If the power is switched off before leaving the menu by quit all
modifications are lost.
5.6 Product data bank
If parameters have to be changed because of different products and labels, the product menu
can be used. The machine offers a data bank in which 14 sets of data can be stored.
If you want to switch to a particular product, select one of the product numbers by pressing
NEXT or PRIOR and confirm with ENTER .The new parameters are valid now.
After switching to a new product bank the machine assumes the label roll has been changed or
that a parameter such as STOD is different and so requires an initialisation of the label position
at the dispensing edge. This is done by pressing the FEED key after loading a new product
bank at which time the machine will move the first detected label edge to the dispense position.
Note: If the FEED key is not pressed after loading a new product bank the first
detected label edge will be moved to the dispense position at the first signal from
the product sensor!
Note: The function FACT available in the configuration menu clears all the product
banks.

can be reduced particularly with long labels having small areas to be printed.
„SS.4“ 4inches/second; same for 5- 12 inches per second
Note: For print applications requiring longer computation steps (e.g. consecutive
numbering) the feeding speed is not to be selected too high to avoid heavy slowing
down to „0“ and re-acceleration to the printing speed.
When changing the print speed (PSPD) the slew speed (SSPD) will be set
automatically identical to the print speed (PSPD). If a different slew speed is
required it has to be adjusted new.
Mode of gap recognition ____________________________________________GAP
AUTO: Default adjustment, for all materials with a difference in light transmittance of more
than 2 digits at gap and label (see description of sensor check).
MAN: The range of automatically measured values for gap recognition may be defined
specific to a label material. This feature helps to feed correctly materials with high
contrast pre print areas which would be detected as false gaps. This contrast
areas should be measured before adjustment by means of the sensor check, the
corresponding adjustment value is identical or less than the value measured at the
effective gap.

Sensitivity of the label sensor _____________________________________ PUNS
Note: High sensitivity adjustment may cause the recognition of gaps which are
physically not exciting. A too high sensitivity may lead to recognition of gaps which
are effectively not available. Those could be contrasts at pre-printed areas,
changing material thickness or perforations.
„SP.1“ High sensitivity for narrow gaps or perforation
„SP.8“ Low sensitivity for clearly recognisable gaps
Foil Auto-Economy, Thermo/Thermo-Transfer Print ___________________ FMOD
The foil feed can be interrupted between printing cycles by means of the foil auto economy, by
which foil is saved particularly with long labels with small areas to be printed. The automatic
mode is to be activated with blank areas of a length from. approx. 18 mm.
Selection between thermo - transfer and thermo print is possible. This selection is necessary
for switching the FOIL END RECOGNITION.
„CONT“ Thermo-transfer print
„SAVE“ FOIL auto-economy
„NONE“ Thermo print
Note: Thermo print depends on your material. Do tests before using this mode.

Value of print head resistor _______________________________________ HRES
In order to optimise the print quality the value of the head resistor (noted at print head 11,4 dot/mm print head = 1000 - 1500 Ohm) has to be keyed in when exchanging the print
head.
CAUTION! - The machine is connected to mains. Only authorised personnel
may open the cover. Operation without this cover is not allowed.
This adjustment is not affected when performing the factory setting. Take readings of value and
key in accordingly
„XXXX“ Possible value is between „1000“ and „1500“
Lowering the head temperature _____________________________________HEAT
Printing full-surface print images inordinately heats up the print head, and therefore also the
thermal transfer ribbon. In order to ensure a uniformly good print image, the parameter HEAT is
used to decrease the power supply proportionately to the temperature of the print head.
xxHR Value range: 00 to 50; unit interval: 10; default: 00
xx = 00 No temperature reduction
xx = 10, 20, ..., 80 up to 10, 20, ..., 80 percent temperature reduction if the print
head is hot
Offset for head voltage ___________________________________________ HVOF
Here an offset value can be added to the value transmitted by the printer (#HV or #!H) to allow
for different printer properties.
Xxxx Values from -50 to +50 are possible (display -50 ... 0 ... 50)

units are set back to zero in this moment.
Routine to gap detection___________________________________________ LREP
The maximal length for not detected gaps can be varied. For difficult detection, i.e. little
differences in light transmittance from gap to label it is recommended to shorten the search
length in order to save labels when gaps are not found. During search no print is performed.
„R 0“ After a printed label a gap must be detected, otherwise an error message
interrupts the running print job. Ditto for search length up to max. = 5 x label length
after the last printed label, subsequently the error message appears.

7. Remote programming
The machine has a serial interface according to the standard RS232C. Via this interface
parameters can be adjusted. All received commands are tested for syntax and legal value
range.
Invalid commands and parameters are ignored. An error message is not given in this case.
All commands received over the serial interface are tested for syntax and range; invalid
commands and out of range parameter values are ignored. A warning message is not given in
these cases. However in the case of framing, parity or overrun errors the warning "W__3" is
generated.
The commands are made up of sequences of ASCII characters. Each command starts with "#"
and "!" followed by a 4 character code. The reception of the "#" character indicates the start of
a new command to the machine.
The codes are similar to the parameter names shown in the display.

8.2 Dispenser Error Messages
In case of an error message the relevant output is switched. The signal can be used for
interconnection with an external machine control.
STO! Power-fail message
The message STO! appears in the display as the machine is switched off or if the mains supply
voltage has fallen below specification.
The message STO! (store) indicates that the machine has stored some parameters internally
as a power fail condition was detected. The error output is switched active and the ready output
inactive simultaneously with STO! appearing in the display.
If the mains supply voltage only experiences a drop in level and then returns to a correct level
then the ready output is restored to its previous condition but the message STO! will remain in
the display to indicate that there has been a problem with the mains supply.

9. Card plug in modules
These plug in modules are provided for the optional font and logo cards. Use PCMCIA cards up
to a size of 2 MB only. There is a maximum of 1 logo card alone or together with a font card –
as well one or two font cards are possible. Logo Cards and data bank cards are formatted by
the printer itself.
Font cards are to be programmed by supplier only.
CAUTION! - Exclusively plug in cards approved by the manufacturer must be
used. Insert, remove, or exchange card not until 60 seconds after
disconnection of unit.

9.2 Memory types
9.2.1 PROM card (Programmable Read Only Memory)
Programmable only with a special program unit (EPROM burner) – it is a on time card, normally
used to store fonts and logos witch are used again and again in the same shape size or look
like. The card will be programmed in the factory due to the customer wishes.
Memory size and capacity depends to the printer.
9.2.2 EPROM card (Erasable Programmable Read Only Memory)
Programmable only with a special program unit (EPROM burner) – it is a on time card, normally
used to store fonts and logos witch are used again and again in the same shape size or look
like. The card will be programmed in the factory due to the customer wishes. The difference
between EPROM and PROM card is that the EPROM card can be cleared by using ultra violet
light.
Is not used in our printer.
9.2.3 EEPROM or E²PROM (Electric Erasable Programmable Read Only
Memory)
The function is similar to an EPROM card – to clear the memory there is no light used, it works
with electric power. The clear procedure is very slow. The data are hold in the memory after
power down – without battery !
Is not used in our printer.
9.2.4 FLASH RAM / PROM card
A name used and defined by the company INTEL witch has used this technology first. The
memory is build similar to the EEPROM but can be cleared in single sectors. A low voltage (5V)
is enough to clear the memory and this voltage is available in the most places (PC/printer). The
clear procedure is very fast, the data’s are stored in the memory after power down – without
battery.
This card is re programmable and can be programmed in a PC with the data’s. Stored on this
card type can be fonts and logos – same as on the EPROM card. In difference it is possible to
store as well formats.
Memory size is different depending on card type and printer.
9.2.5 RAM card (Random Access Memory)
Very fast, volatile memory. Each single memory cell is programmable and readable. Using
RAM card means that a battery is used to make the memory non volatile- the data’s are still in
the memory after power is switched off, reasoned by the power of the battery.
The card type is re programmable and depending on the printer type the card can be
programmed in the printer (via down load) or at the PC. It is possible to store – similar to the
EPROM card, as well logos fonts but different to the EPROM card as well formats
Memory size is different depending on card type and printer.

10. Connections and signals
This machine has a number of inputs to connect sensor’s and a control. Outputs are available
for applicators, a printer and other purposes.
10.1 Output signals
This machine has eight outputs, which switch the output from open circuit to + 24V. The
maximum current must not exceed 500 mA. The four signals for error messages, machine
ready, low material and warnings are available for other machines in the process or additional
alarm signals. For connecting an applicator three signals are available and one additional for
the printer.
The output signals are available at terminal connector CN33 on the main board. The wiring of
the terminal is shown otherwise.
10.1.1 Error and warning output
The outputs for errors and warnings are available on the terminal CN33 and optional on the I/O
plug. The signals are switched active (+24V) if an error or warning occurs. When the error or
warning is erased, the signal becomes passive again.
10.1.2 Printer output
This machine can be connected to a printer. To use the printer the PDT parameter should be
adjusted.
A new label cannot be dispensed until the printer dwell time set in PDT is over.
10.1.3 OD-Control output
This output is switched active (+24V) if the OD-Control input is switched active during
dispensing.
10.1.4 Ready output
This output shows when the machine is ready for labelling. This output is switched inactive if
there is:
• an error message appears in the display
• the mains supply voltage has fallen below specification
• the machine requires initialisation
• in OFF condition.

10.2 Applicator modes
The machine is able to dispense the label direct on the passing product. There is also the
possibility to drive without any external control a wide range of applicators.
10.2.1 Signals for direct dispense
For direct dispensing the airstream signal can be used to control a pneumatic driven dispensing
edge. The start of the airstream signal (= motor run signal) could be behind the start of the
dispense motor, adjusted with the function APT3. The signal is switched inactive, when the
label dispense has been completed. Also the stop could be adjusted with the function ASTP to
switch inactive before or behind the dispense motor stop.
