Change parameters of a message in production
The fields in this dialog box are described below. The Scrolling action, Transparency
printing and Inverse printing parameters cannot be changed to an existing message.
They must be set prior to creating a message.
Change message parameters
Message editing/Parameters/Message
This dialog box contains all the settings you need to adapt the message to the production line. These settings are specific to each message.
Default parameter values
The default message parameters are common to all messages and are configured in the Printer preparation/Parameters/Message menu.

Scrolling action
The setting for this parameter depends on how your printer is set up on the production line and on the results you want to achieve from the printing operation.
The key shows the direction of travel of the object. Press tab key a second time to enlarge the image.
Press the and arrow keys to change the scrolling action displayed.
This parameter can be used in conjunction with the Transparency printing and Inverse
printing parameters to read the message in various different ways.
Transparency printing
Check this box to apply transparency printing to the message.
Inverse printing
Check this box to apply inverse printing to the message.
DIN characters
Check this box to obtain a message written like this:
If you have selected a "chimney" font in the function ( Message editing/Font/Select font), printing output will be like this:

Printing repetition
This parameter is used in object set-off mode (Set off field set to OBJECT) to repeat printing at a pre-set number of times regardless of the length of the object be marked. Enter a value between 0 and 255.
Example:
Printing repetition: 1 means that a single message is printed and is not repeated. Printing repetition: 2 means that two messages are printed for every DTOP received.
Print speed
If the product travels at a constant speed (Speed measurement field set to CONSTANT SPEED), enter the speed value in millimeters per second.
Tacho division
This field is only applicable if tacho mode is selected (Speed measurement field set to TACHO)
Enter a number between 1 and 255. Increase or decrease this value according to adjust the printed character width obtained when printing.
Algo
Choose an algorithm or allow the printer to select the most appropriate one for the programmed print speed automatically (AUTO).
The printer will suggest a selection of suitable fonts in the function ( Message editing/Font/Select font) on the basis of the setting made.
The message editing fonts and available print lines are determined by the algorithm chosen.

REMINDER New algorithm or print speed settings cannot be made on messages that have already been created.
The content of the message has to be deleted first if you want to change these parameter settings.
Forward margin
Enter a forward margin value (in millimeters).
This parameter represents the space between the point where the object is detected and the point where the message starts to be printed if the printed message starts from the first character.
Return margin
Enter a return margin value (in millimeters).
This parameter represents the space between the point where the object is detected and the point where the message starts to be printed if the printed message starts from the final character.
Interval
Enter an interval value (in millimeters).
This parameter represents the space between two print operations in repetitive set-off mode (Set off field set to REPETITIVE) or if "Printing repetition" is active.
Top filter
Enter a time value (in s).
This parameter is the minimum time value that the object detection signal has to reach to be taken into account by the printer. You can increase this time value if you have noticed that messages have been printed at the wrong time.
Set off
To determine how printing is to be set off. Options:
MANUAL OBJECT or MANUAL AUTO: If you want to perform manual print tests. . MANUAL OBJECT: Printing is triggered when you press the spacebar on your keyboard. Printing is performed every time the spacebar is pressed.
. MANUAL AUTO: Printing is triggered when you press the spacebar and is repeated until you press the spacebar again.
This means that you can print out the same message automatically several times between each time you press the spacebar manually.

Options:
OBJECT or REPETITIVE when the system is in operation.
. OBJECT: Printing is triggered when the DTOP signal is receive by the printer. You print one message for each object detected.
. REPETITIVE: Printing is triggered when tDTOP signal is received and remains constant, printing continues for as long as the DTOP signal is activated or until the specified number of repeat print operations is reached.
Speed measurement
Specify speed measurement method: CONSTANT SPEED
Speed not measured - speed assumed to be constant. A printing speed needs to be entered in mm/s
TACHO
Select this field if you want to use a tachometer (tachometer pulse generator/Encoder). This speed detection device is used to synchronize the printer print speed continuously with the speed at which the objects to be printed travel along the production line. It is particularly useful when the object travel speed is not constant.
See "Input/Output connections" section contained in this manual for further information on connecting the photocells and the tachometer.
Specify print resolution
Printer preparation/Initialization/Message/Horizontal resolution Enter horizontal resolution value according to the head used:
G head: 2.8 dots/mm. M head: 4.5 dots/mm. P head: 7.0 dots/mm.
