Project parameter Range of settings
| | Impulse generator source
Internal generator , External source
The source of timing signals, i.e. the signals that determine when consecutive columns of a text are
printed:
- Internal generator : printing at a constant speed timed by the printer’s internal generator.
The printing speed is set with the Conveyor speed parameter.
This mode is recommended when the conveyor belt travel speed is known and steady.
- External source : printing at a speed that depends on how fast objects to be labeled move on
a factory conveyor.
Printing is timed by a rotational speed sensor (an encoder) connected to input
in the con-
trol unit.
To adjust printing speed with an encoder correctly it is required that the
Encoder constant
parameter be set.
This mode is recommended when the conveyor belt travel speed is not steady.
| | Trigger source
Internal , External, Both
Select a source of the signal that triggers printing of a project or a project part preceded by a Line
divider ‑type object :
- Internal : printing is triggered by a built‑in photodetector,
- External : printing is triggered by an external photodetector connected to input in
the control unit,
- Both : printing is triggered by both of the above‑mentioned photodetectors.
The trigger signal can be further configured with the parameters | | Trigger type and | |
Trigger signal mode .
The parameter | | Trigger source applies when the printer is not in continuous printing mode
(the value of the parameter | | Printout repetition differs from ).
| | Trigger type
Edge , Level
The Trigger type parameter defines the printer’s response after print triggering :
- Edge : when the active edge of the trigger signal occurs, the printer makes one printout con -
sisting of a defined number of reprints (the project parameter | | Printout repetition ),
and then awaits the re‑occurrence of the active edge of the trigger signal to make another
printout; the mode is dedicated to printing one printout on every object.
For examples see
Fig. 57 on page 94 and Fig. 58 on page 94 .
- Level : when the active edge of the trigger signal occurs, the printer starts making printouts
consisting of a defined number of project reprints (the project parameter | | Printout
repetition ) and continues printing the reprints as long as the object being labeled is within
reach of the photodetector selected as the source of the trigger signal; the mode is dedicated
to making many printouts on one object or to making printouts on continuous objects, e.g. on
tubes.
For examples see
Fig. 55 on page 93 and Fig. 56 on page 93 .
The parameter | | Trigger type applies when the printer is not in continuous printing mode
(the value of the parameter | | Printout repetition differs from ).
