How to Configure the Printer

CLARiTY Configuration Manager

As coding and labelling equipment have become increasingly versatile
and flexible with a wide range of applications, the number of variables
that can be configured within a printer has become very large. Although
printers are pre-programmed with default values, as the extent of the
application increases, it becomes less likely that the default configuration
is ideal. This can lead to a large and cumbersome menu tree on the
printer’s controller that users have to work with.

Videojet 8520 Service Manual

Most printer variables are set during the installation process. The
variables are set to values that tailor the printer to the application. Once
set, these variables only need to be changed when the application for the
printer changes. As such, there is no need to make these installation
parameters available in the printer interface. They are set through a
configuration programme called CLARiTY Configuration Manager.

Rev AA How to Configure the Printer 4-3

Videojet 8520 Service Manual

Figure 4-2: CLARiTY Configuration Manager

The CLARiTY Configuration Manager (Figure 4-2) is a PC software
program, that provides the following basic features:

• Setting of the printer variables

• Saving/retrieving a set of variable values to a PC file for later/
repeated use

• Downloading a set of variables to the printer's CLARiTY controller for
non-volatile (permanent) memory storage in the printer

• Uploading a set of variables from the printer for review/comparison/
modification

• Updating the system software

• Saving/retrieving language files

• Saving/retrieving job, font, and graphics files

• Snapshot of CLARiTY screens

4-4 How to Configure the Printer Rev AA

Videojet 8520 Service Manual

As a result, the CLARiTY controller retains the availability of a small
number of operating variables for the user to change. Apart from making
the CLARiTY control system more simple and user-friendly, it also
provides an increased level of printer system integrity, because the
configuration variables cannot be accessed from the printer itself, but from
a connected PC.

If the printer is installed to run in a standalone mode (i.e., the printer is not
networked), the PC is only linked briefly (via the RS232 serial or ethernet
port) for the period of upload/download of the variables (a few seconds).
The PC would then be removed.

In a networked environment, system administrators could have direct
access to the printer, while line operators are limited to accessing only the
operating variables that are relevant to them.

How to Install the CLARiTY Configuration Manager

CLARiTY Configuration Manager is available in the USB with the
Operator Manual. To operate the USB, the system requires Windows 7.0
or later operating system with minimum 5 MB capacity and ethernet or
serial port. The installation routine commences automatically.

Do the following tasks to install:

1 Insert the Operator Manual USB.
2 Click on the USB drive.
3 Click on CLARiTY Configuration Manager in the home page.
4 Run the CLARiTYConfig.exe file.

Follow the on-screen instructions to install the software. The software
is installed in the PC and is ready for use.

Purging Options

Note: Purging features are optional and they are in disabled mode by default.

Timed Purging

Purging of the cartridge is carried out at timed intervals when the
printhead is powered on but not printing.

Timed Purging is set up using CLARiTY
can set the length of purge and the time interval for timed printing.

If the printhead is powered on and has not been printing, the printhead
will purge once it reaches the inactivity period of time defined by the user.
The function can be turned ON or OFF. When there is no sufficient time to
complete the purge, purging will be aborted.

Note: The purge length varies as per the ink used and hence you can enter the
purge length as required.

Product Detect Purging

Purging of the cartridge occurs when print is triggered prior to printing if
the timer has expired. The timer is reset.

This purging is a user configurable timer. It can be turned ON or OFF.
When the printer is in ONLINE state, ‘Product Detect Purging’ will be
active. The print resets the timer. The length of purge is defined by the
user. The timer must have elapsed for a purge to be triggered before the
next print. Once elapsed, purging occurs before the next print, triggered

To ensure the correct stitching together of the image or job, it is necessary
to tell the printer, the distance between the first line of each individual
printhead.

How to Configure the Job Settings in CLARiSOFT

The job is set up in CLARiSOFT. The settings are made specific to the
active print job only (.CIFF file).

Note: All the dimensions are in millimeters (mm).

Size & Resolution

Printheads

When a new file is created in CLARiSOFT, the corresponding number of
print fields is defined by the user. One printhead corresponds to one print
field. The job can be user-defined within this print field (no restrictions in
terms of numbers of lines, etc.). Only the maximum print heights are
predefined.

One printhead = maximum print height 12.7 mm (0.5”)
Two printheads = maximum print height 25.4 mm (1”)
Three printheads = maximum print height 38.1 mm (1.5”)
Four printheads = maximum print height is 50.8 mm (2”)

On selecting the number printheads, the grouping will also be
determined.

Note: Printing requirements must be understood to set up the message and
controller parameters correctly.

Examples:

• All individually: Each head prints different data within a job. If this
setting is selected, whenever you create a new job you will be given
exactly the number of print fields that were set in Number of printheads.

• All like head 1: All the printheads print the same data as head 1. In
this setting, only one print field is made available. The text entered for
head 1 applies automatically to all the heads which were predefined
for this job under Number of printheads.

• Heads 3/4 like heads 1/2: Heads 3 and 4 print the same data as heads
1 and 2 (example: two-sided carton printing). In this case only two
fields will be available for entering the print data. The text entered
there applies equally to heads 1/2 and 3/4.

Note: Two groups of two printheads printing the same data.

Nozzle Rows

The ink cartridge has two nozzle rows. The printer can be set up to print
with both nozzle rows or only one nozzle row (left/right). This is set up
during commissioning. With this setting, you can select vertical resolution
between 300 dpi and 600 dpi. This has an influence on the density value of
the printed text and the ink consumption of the CLARiTY.

Note: With a single nozzle row, the printed text is printed vertically with 300
dpi, and with two nozzle rows, it is printed with 600 dpi.

dpi = dots per inch (1 inch = 25.4 mm)

Printing examples:

Resolution

The resolution of the print job is set up in CLARiSOFT. This sets the
horizontal resolution. This setting specifies the number of dpi used for
printing in the direction of movement of the product.

The resolution value depends on the speed of product and the ink
cartridge used.

Note: You can choose a vertical resolution of 300 or 600 dpi and a horizontal
resolution of 60, 75, 100, 120, 150, 180, 200, 240, 300, 360, 450 or 600 dpi.

DataMatrix Optimisation for different print resolutions.

DataMatrix codes should be dimensionally as square as possible. Codes
where either the x (length) or y (height) dimension are unequal can result
in less-than-optimal bar code grading scores due to axial non-uniformity.

Due to the range of potential module sizes and the inherent ability to print
in different vertical and horizontal resolutions, it is possible for a given
combination of module size and resolution to result in a sub-optimal score
due to axial non-uniformity. While the printer attempts to preserve the
vertical height of the code, it can happen that depending on the selected
resolution, it is possible that the optimal module size would require a
fractional drop of ink. As this is not possible, the printer will round up to
the next amount of complete drops.

The following table summarizes the recommended DataMatrix module
sizes for a given combination of vertical and horizontal resolutions to
prevent the unintended difference in DataMatrix length and height as
described above.

Print Allocation

Some coding applications demand strict control of batch sizes for example
controlled pharmaceutical products.

To work in such production situations it is useful to set the coder so that it
only prints a precise number of codes before shutting down and waiting
for the next batch instruction.

This is called a Print Allocation and it is administered by another
computer or line controller.

When the production control PLC or PC authorises a new production
batch, a special message can be sent to the printer using the External Serial
Interface. This message selects the Job to print, any variable data in the job,
and the allocation count, which is the production batch size. These
messages can be stored in a queue in the printer and the size of the
permitted queue is configurable.

The printer prints the current job until the number of products printed
equals the allocation count sent by the controller, at which point it stops.
When one allocation batch has been completed, the next job is
automatically selected by the printer if there is a pending job in the queue.
If there is no pending job in the queue the printer will not execute any
further printing operations until a new allocation is sent to it.

Setup of the allocation operation for the printer is performed via the
CLARiTY configuration manager, where the following parameter can be
set:

• Maximum Queue Length: Defines how many jobs are permitted to be
in the Job queue.

The configurable inputs and outputs also can be setup to trigger on
certain events related to Print Allocations.

• Clear Print Queue (Input) - Resets the print job queue and deletes all
jobs in the queue.

• Job allocation has completed (Output): The current allocation of prints
has been completed.

• Job Update queue is full (Output): The maximum permitted number
of jobs in the queue has been reached.

• Job Update Queue is not full (Output): The maximum permitted
number of jobs in the queue has not been reached.

• New Job allocation is received (Output): A new job allocation message
has been received by the printer.

When allocations are enabled, it is possible to view the job queue at the
CLARiTY panel in two different ways.

Repeat Print Mode

The Repeat Print Mode function allows the print material to be printed

material and for the multiple printing of a single carton or other kind of
print material.

If Repeat Print Mode is not selected, the photoelectric cell will trigger a print
every time it detects new print material. This is the most commonly used
setting for the printing of unit loads (example: cartons).

Figure 4-28 shows the signal level caused by a carton edge.

This uses inhibit print function (input). This enables continuous auto print
until the product is no longer there.

Variable Mode

The variable mode is an advanced feature which is used to supply variable
fields with data from an external source (serialization of the print data).

The user can set on which type of variable fields printing is to be effected.

Two modes are available for serialization of the print data.

In Once mode, each data record is printed only once. If no more data are in
the print buffer, the CLARiTY goes in WAIT mode until new data is
transferred into the print buffer.

In Continuous mode, a data record is printed repeatedly, until a new data
record is transferred or the CLARiTY is stopped.

How to Set up Counters

Counters will be set up in CLARiSOFT (example: consecutive numbering).

Counters

Counter status

Counter status defines the starting value for the counter. The starting
value can be entered as variable data by the user. As a standard, the
counter value will be remembered as long as the job is selected. To reset
counter to starting value, you must reselect the job. The counter value can
be default or user-entered value. The maximum value of the counter is

999.999.999.

Number of Series

The Number of Series is the number of products to be identified with the
same counter value. This will be set up in CLARiSOFT. It is set up as user­entered fields (variable).

Example: The first product batch is comprised of 50 packages:

Number of series 50 ƒ× The first 50 packages will be printed with the same
counter value (= batch number).

Batch Start Value

By specifying a batch start value you can adjust the size of the first batch.
Example: If the quantity in the first batch is lower (rejects in the start up of
production, etc.), this can be specified here.

The changed quantity only applies to the first batch. After this the value in
Number of batches is used as the basis. If 0 is entered, the first batch has the
full number of units.

Example, the batches are comprised of 50 packages per batch.

In the first run through, however, 10 packages are rejected before the
printing process can start up. Therefore, 40 is entered in "Batch start value"
and 50 in Number of batches (applicable for all subsequent batches).

Counter Final Value

The counter counts up or down until this value is reached. The next step is
determined by the next function Reached Final Value.

Every activated shift has a three-part field for entering the start of the shift
and the desired code. The field always begins with the name ‘Shift’ and
the ‘No.’ of the shift in front. This field cannot be altered. The following
part of the field is to enter the start of the shift, either in 24-hour or 12-hour
format depending on the hours format. The third part of the field is for
entering the desired code for the shift designation. A total of 16 characters
are available here.

Use the arrow keys to navigate within the input fields. The only time
entered for each shift is the time at which the shift begins. The duration of
the shift is derived automatically from the start of the next shift.

Updating the CLARiTY Operating System

The CLARiTY operating system can be upgraded by a process called a
‘CLARiTY Update’.

The current version of the software appears at the page Tools > Diagnostics
> Control > Versions where the software part number can be read.

The part number has the format:

Part.Version.Service Pack

For example: 402571.r01.SP1 represents part number 402571, Revision 01,
Service pack 1.

If the software is corrupted or was not installed correctly, the software
part number states “Incompatible Software Versions”. When this message
appears, a CLARiTY update must be performed immediately to correct
the situation, otherwise it results in unpredictable printer behavior.

The printer should be used only when a valid part number appears in the
part number window.

There are two ways of performing a CLARiTY Update:

1 Connecting the printer to a PC, that runs CLARiTY Configuration

manager

2 Inserting a USB memory stick containing the update file into the

printer

Before performing a CLARiTY
parameter archive is saved using CLARiTY Configuration Manager (Refer
“How to Archive the Current Parameters” on page 4-14).

CLARiTY Update via PC

It is recommended that when updating via PC, the PC-Printer connection
is done via Ethernet. This process is faster (refer “How to Connect the
CLARiTY Configuration Manager to the Printer using an Ethernet cable”
on page 4-7 for connecting a PC to the printer via Ethernet).

You must have the CLARiTY Update CAB file stored on the PC disk.
Contact your local service representative to obtain the correct file for your
printer.
