4.4.4.10. Monitoring
In the main MEN item and then the HV VALUE,PHOTO,SHAFT,AirP state
item.
In the
print
mode, the START PRINT command is followed by the application of high voltage ( HV ) to
the head. HV is needed to deflect a jet of ink drops. The actual voltage value is displayed on the
terminal with the HV VALUE,PHOTO,SHAFT,AirP state command. The command helps diagnose
some faults resulting from poor print quality and high voltage errors.
If the printer is not in the
print
mode, the
HV VALUE,PHOTO,SHAFT,AirP state
command results in
displaying the figure 0.00 .

4.4.4.11. Defining Some Print Parameters by Measuring Conveyor Travel
Speed
In the main MENU select the fo
CONVEYER MEASUREMENTS .
Place two objects on a factory conveyor at the distance of one meter ( 1m ) from each other and let
them move in front of the photo detector after the comm CONVEYER MEASUREMENTS and has
been selected. The results of measurements of the following parameters are displayed on the
terminal:
´
Travel speed (a number of metres/minute [ m/min ]) at which objects move in front of the print
head. The figure can be utilised directly or used to determine the setting for the Cnv spd m/min
print parameter,
´
Number of pulses generated by the external encoder per distance unit (pulses/ metre, p/m ). It is
called the encoder constant. The figure can be utilised directly or used to determine the setting for
the
Enc const p/m print parameter.
NOTE:
•
In order to determine the encoder constant properly, the Generator print parameter needs to
be set to SHAFT and the encoder axle needs to rotate while a measurement is taken.
•
If the Generator print parameter is set to GEN , the encoder constant is 0 (zero).
•
Objects can be placed on the conveyor at smalle or greater a distance than 1 m. Then the
figure displayed on the terminal needs to be divided by a multiple of 1 metre. For example, if
the distance between the objects is 0.2 m, then the resulting encoder constant is five times
greater than that indicated on the terminal.
